Why Strength Training is a Game-Changer for Men

Strength training is more than just lifting heavy weights and building bigger muscles; it is a cornerstone of long-term health and vitality for men. The benefits extend far beyond the mirror, impacting everything from your metabolism to your mental well-being. Committing to a consistent strength training program is one of the best investments you can make in your physical and mental health.

One of the most significant benefits is an enhanced metabolism. Building muscle increases your resting metabolic rate, meaning your body burns more calories even when you’re not exercising [1]. This makes it easier to manage your weight and reduce body fat, particularly the dangerous visceral fat around your abdomen that is linked to chronic diseases like heart disease and type 2 diabetes [2]. As you build more muscle and lose fat, you will not only look leaner and more defined, but you will also be fundamentally healthier.

Beyond the physical, strength training has profound effects on mental health. Regular resistance exercise has been shown to boost self-esteem, improve body image, and reduce symptoms of anxiety and depression [3]. The act of lifting weights and progressively getting stronger fosters a sense of accomplishment and mental fortitude that carries over into all aspects of life. Furthermore, it improves bone density, reduces the risk of injury by strengthening connective tissues, and enhances your overall quality of life, ensuring you stay active and capable as you age.

Building a Habit That Lasts a Lifetime

The magic of a 30-day challenge lies in its power to build habits. Research shows that it takes time and consistency to form a new routine, and a 30-day period is an ideal timeframe to establish a solid foundation for a lifelong fitness journey [4]. The goal here is not just to get through the next month, but to integrate exercise into your life so that it becomes as natural as brushing your teeth.

Consistency is the single most important factor for success. To achieve this, you need to remove as many barriers as possible. Start by finding a time in your day that you can consistently dedicate to your workouts. For many, morning or afternoon sessions are the most reliable. Evening workouts can be risky, as daily fatigue or unexpected commitments after work can easily derail your plans. Block out this time in your calendar as a non-negotiable appointment with yourself.

Proximity is another key factor. Choose a gym that is conveniently located either near your home or your workplace. The less friction there is in getting to your workout, the more likely you are to stick with it. This 30-day challenge is your opportunity to prove to yourself that you can commit, stay consistent, and achieve your goals. It’s about building the discipline and momentum you need to start your fitness journey on the right foot.

The 30-Day Challenge Workout Plan

This program is designed to be intense and effective, requiring one hour per day, five days a week. We will use a 5-day split focusing on a push/pull/legs structure with additional core work. This ensures that each muscle group is worked thoroughly and has ample time to recover. Fridays and Sundays will be active recovery days, where you will perform 15 minutes of light stretching at home to aid recovery and improve flexibility.

For this program, you will use a variety of equipment including dumbbells, kettlebells, barbells, machines, sledges, medicine balls, and your own bodyweight. Starting from week two, you will increase the intensity by including a superset for each workout, increasing the total number of exercises to eight.

Here is the workout split:

  • Day 1: Chest & Back
  • Day 2: Shoulders & Biceps
  • Day 3: Legs & Triceps
  • Day 4: Back, Core & Abs
  • Day 5: Full Body Functional
  • Day 6: Active Recovery (Stretching)
  • Day 7: Rest

Nutrition: Your Fuel for Transformation

Nutrition is just as important as your training. To achieve the goal of losing 5kg in 30 days for an 85kg individual, you need to be in a consistent calorie deficit while consuming enough protein to preserve and build muscle. This process is often called muscle building while in a deficit.

Let’s break down the numbers. To lose approximately 0.5-1kg per week, a daily calorie deficit of 500-700 calories is required. For an 85kg man who is moderately active, a maintenance calorie intake is roughly 2,500 calories. Therefore, a target intake of around 1,900 calories per day is a good starting point.

Here’s a sample macronutrient breakdown:

  • Protein (1.6g per kg of bodyweight): 1.6g x 85kg = 136g of protein. (544 calories)
  • Fats (25% of total calories): (1900 x 0.25) / 9 = ~53g of fat. (477 calories)
  • Carbohydrates (Remaining calories): (1900 – 544 – 477) / 4 = ~220g of carbs. (880 calories)

To make this manageable, use an app like MyFitnessPal to track your daily intake. Focus on lean protein sources like chicken breast, fish, lean beef, eggs, and Greek yogurt. For supplements, consider incorporating Clear Whey Protein to help you meet your protein goals and Creatine Monohydrate to improve strength and performance.

30-Day Beginner Gym Challenge: 5-Day Strength Training Split for Results

Get in Shape in 30 Days and Build a Lasting Habit with Strength Training

By Will Duru, BSc (Hons) Sport and Exercise Science, Award-winning Personal Trainer

Welcome to your 30-day beginner gym challenge! I’m Will Duru, and with over 10 years of experience in strength training, I’m here to guide you on this exciting journey. This program is designed to help you build a strong foundation, develop healthy habits, and see real results in just one month. We’ll focus on a 5-day workout split that’s perfect for beginners, along with essential nutrition and supplement advice to maximise your progress. The goal is not just to transform your body, but to create a sustainable fitness routine that you can stick with for the long haul.

This challenge is built around a structured 5-day workout split, a highly effective method for beginners to build muscle and strength. Research shows that both full-body and split-body routines are effective for beginners, but a split routine allows you to focus on specific muscle groups each day, which can be less overwhelming and more motivating when you’re just starting out [4]. We’ll be using a push/pull/legs format, with dedicated days for core and high-intensity interval training (HIIT) to ensure a well-rounded program.

Day 4: Cardio (Zone 2 and Zone 3)

This day is dedicated to cardiovascular health. Spend 60 minutes on a cardio machine of your choice (treadmill, elliptical, bike). Aim for 40 minutes in Zone 2 (a pace where you can hold a conversation) and 20 minutes in Zone 3 (a more challenging pace where conversation is difficult).

Day 5: HIIT Workout

High-Intensity Interval Training (HIIT) is a fantastic way to burn calories and improve your cardiovascular fitness in a short amount of time. Perform each exercise for 30 seconds, followed by 30 seconds of rest. Repeat the circuit 4-5 times.

  • Jumping Jacks
  • High Knees
  • Burpees
  • Mountain Climbers
  • Bodyweight Squats

Nutrition for Success

Your efforts in the gym will only take you so far without proper nutrition. To build muscle and lose fat, you need to fuel your body with the right nutrients. Focus on a balanced diet of lean proteins, complex carbohydrates, and healthy fats. Aim for a slight calorie surplus if your goal is muscle building, or a slight calorie deficit if your goal is fat loss. Remember to drink plenty of water throughout the day to stay hydrated.

Can Exercise Really Help with Mood Swings or Anxiety

Supplements to Boost Your Results

While not a replacement for a healthy diet, certain supplements can help you achieve your goals faster. For this 30-day challenge, I recommend two key supplements:

  • Clear Whey Protein: Protein is essential for muscle repair and growth. Supplementing with whey protein, especially after a workout, can significantly enhance muscle hypertrophy and strength gains [1]. Clear whey is a lighter, more refreshing alternative to traditional milky protein shakes.
  • Creatine: Creatine is one of the most researched and effective supplements for increasing strength and power output. Taking 3-5 grams of creatine daily can help you lift heavier and perform more reps, leading to greater muscle growth over time [2].

Track Your Progress with the 12Reps App

To get the most out of this 30-day challenge, I highly recommend using a workout tracker like the 12Reps app. You can build this entire routine in the app, track your sets, reps, and weights, and monitor your progress over time. The app also features over 1,500 exercise demos to ensure you’re performing each movement correctly and safely. You can even pre-plan your workouts and share your personal bests with friends on social media. Download the app for a free trial and take your strength training to the next level.

The Importance of Consistency

Remember, consistency is key. Sticking to this program for 30 days will not only produce visible results but also help you build a lasting habit. Resistance training is medicine; it can increase lean muscle mass, boost your metabolism, and improve your overall health in numerous ways [3]. So, commit to the challenge, stay consistent, and get ready to transform your body and your life.

The Ultimate Gym Leg Day: Kettlebell, Barbell, Dumbbell & Machine Workout | 12Reps App

Ultimate Lower-Body Workout: Kettlebells & Machines | 12Reps App

With over a decade of experience as a personal trainer, I’ve seen what truly works for building serious lower-body strength. If you have access to a gym and want to build powerful, well-rounded legs, you need to use all the tools at your disposal. Forget sticking to just one type of equipment; the real magic happens when you combine them.

In this article, I’m going to share my ultimate lower-body workout that strategically uses kettlebells, barbells, dumbbells, and machines. I’ll explain why this multi-tool approach is so effective and how you can use the 12Reps app to structure your session and track your progress for unstoppable gains.

The Ultimate Gym Leg Day: Kettlebell, Barbell, Dumbbell & Machine Workout | 12Reps App

Why Use Kettlebells, Barbells, Dumbbells, AND Machines?

To build the best legs possible, you need a variety of stimuli. Each piece of equipment in the gym offers a unique benefit, and a smart program combines them all.

Kettlebells for Functional Power: I always start with kettlebells. Their offset center of gravity is unmatched for firing up your core and building functional, real-world strength. Kettlebell movements are dynamic and explosive, which is fantastic for engaging your entire posterior chain and improving your athleticism. A study sponsored by the American Council on Exercise (ACE) even found that kettlebell training can increase core strength by an incredible 70% [1].

Barbells for Foundational Strength: When it comes to lifting heavy and building a solid foundation of strength, nothing beats the barbell. Exercises like the Romanian Deadlift (RDL) allow you to load up the weight, which is essential for developing your hamstrings and glutes and is a cornerstone of any serious strength training program.

Dumbbells for Versatility and Balance: Dumbbells are fantastic for working on single-leg strength and addressing any muscular imbalances. A dumbbell goblet squat, for example, is a great way to work your quads and glutes while also challenging your core stability.

Machines for Targeted Isolation: Finally, we use machines to isolate specific muscles. After you’ve built fatigue with compound movements, a machine like the leg extension allows you to safely push your quads to their absolute limit, which is a key trigger for muscle growth (hypertrophy).

By combining these four tools, you get a workout that builds functional power, raw strength, and targeted muscle growth. It’s the complete package.

A Trainer’s Guide to Progressive Overload

To keep making progress, you must apply the principle of progressive overload. This means you have to find ways to make your workouts more challenging over time. Here’s how I guide my clients to do it with this program:

  • Go Heavier on the Barbell: Your Barbell RDL is your main strength-building exercise. Focus on adding a small amount of weight to the bar each week.
  • Increase Your Kettlebell/Dumbbell Weight: Once you can complete all reps and sets with perfect form, it’s time to pick up the next weight up.
  • Add Reps: On the leg extension, try to push for an extra rep or two each session before you increase the weight.
  • Control Your Rest: As you get fitter, try reducing your rest periods by 5-10 seconds to increase the workout’s intensity.

The 12Reps app is crucial here. By logging every set, rep, and weight, you have a clear record of what you did last time. This takes the guesswork out of your training and tells you exactly what you need to do to beat your last session.

Ultimate Lower-Body Workout: Kettlebells & Machines | 12Reps App

Nutrition: The Fuel for Muscle Recovery and Growth

You can’t out-train a bad diet. All your hard work in the gym needs to be supported by proper nutrition, especially protein. Protein provides the building blocks your muscles need to repair and grow back stronger.

For those of us who are serious about strength training, research from the Journal of the International Society of Sports Nutrition recommends a daily protein intake of 1.6 to 2.2 grams per kilogram of body weight (that’s about 0.7 to 1.0 grams per pound) [2]. To give your body the best chance to use this protein, spread your intake across at least four meals.

Your meals should be centered around lean protein sources like chicken, fish, eggs, and lean beef. Pair this with complex carbohydrates like sweet potatoes, brown rice, and oats to refuel your energy, and don’t forget healthy fats from avocados, nuts, and olive oil to support your overall health.

Your All-in-One Training Partner: The 12Reps App

I recommend the 12Reps app because it’s designed to make serious training simple and effective.

  • Track and Log Your Workouts Easily: Keep a perfect record of your training to ensure you’re progressing.

As a personal trainer with over a decade of experience, I’m always looking for the most effective ways to help my clients build strength. Today, I want to share a powerful lower-body workout that combines the functional benefits of kettlebells with the targeted muscle-building of machines.

This hybrid approach is perfect for building well-rounded, powerful legs. In this article, I’ll explain the method behind the madness, lay out the full workout for you, and show you how the 12Reps app can be your secret weapon for tracking your progress and ensuring you stronger.

Ultimate Lower-Body Workout: Kettlebells & Machines | 12Reps App

Why Combine Kettlebells and Machines?

I’m a huge advocate for kettlebell training. The dynamic, full-body movements you perform with a kettlebell are incredible for building functional strength—the kind of strength that helps you in your everyday life. The offset weight of the kettlebell forces your core to work overtime to stabilize your body. In fact, research has shown that kettlebell training can increase core strength by up to 70%, which is a massive benefit for your overall stability and power [1].

Kettlebell exercises like swings, squats, and lunges are compound movements that engage multiple muscle groups at once. This makes them incredibly efficient for burning calories and improving your cardiovascular health, all while building muscle [1].

So, why add a machine into the mix? While kettlebells are fantastic for building a strong, functional base, machines like the leg extension allow us to isolate specific muscles. By finishing our workout with a machine-based exercise, we can target the quadriceps directly, ensuring we’ve pushed them to their limit to stimulate maximum growth. It’s the perfect way to get the best of both worlds: functional power and targeted hypertrophy.

Ultimate Lower-Body Workout: Kettlebells & Machines | 12Reps App

How I Structure a Hybrid Lower-Body Session

When I design a program like this for my clients, I always start with the most demanding, multi-joint kettlebell exercises. These movements require the most energy and coordination, so we want to do them when we’re fresh. We focus on big, powerful movements like squats and lunges to build our foundation.

After we’ve built up fatigue with these functional movements, we move to the machine for a ‘finisher’. This allows us to safely push a specific muscle group to failure without needing the same level of stability and control as free weights. This combination ensures you’re building a body that’s not only strong and athletic but also well-defined.

A Personal Trainer’s View on Progressive Overload

To see continuous results, you must follow the principle of progressive overload. This is the foundation of all successful strength training, and it simply means you have to gradually increase the difficulty of your workouts.

For this program, you can progress by:

  • Increasing the Kettlebell Weight: Once you can hit all your reps with good form, it’s time for a heavier kettlebell.
  • Increasing the Machine Weight: The same goes for the leg extension. Aim to increase the weight whenever you can complete all 15 reps.
  • Adding Reps: Before you increase the weight, try adding a rep or two to your kettlebell exercises each week.
  • Reducing Rest: To make the workout more metabolically demanding, try cutting your rest periods to 45 seconds.

The 12Reps app is essential for this. It lets you log your weights, reps, and sets, giving you a clear record of your performance. This data takes the guesswork out of progressive overload, telling you exactly when you’re ready to push harder.

Ultimate Lower-Body Workout: Kettlebells & Machines | 12Reps App

Nutrition for Muscle Recovery and Growth

A tough workout is the signal for your muscles to grow, but they need the right building blocks to do it. That’s where nutrition comes in. Proper nutrition, especially protein intake, is critical for muscle recovery.

So, how much protein do you need? For active individuals, research from the Journal of the International Society of Sports Nutrition recommends 1.6 to 2.2 grams of protein per kilogram of body weight (about 0.7 to 1.0 grams per pound) daily [2]. To maximise your body’s ability to use this protein, you should spread it out over at least four meals.

Build your meals around lean protein sources like chicken, fish, lean beef, eggs, and Greek yoghurt. Don’t forget complex carbohydrates (oats, sweet potatoes, brown rice) to refuel your energy stores, and healthy fats (avocado, nuts, olive oil) to support your overall health and hormone function.

The Ultimate Guide to the Push/Pull/Legs (PPL) and Core Workout Program

strength training app, 12reps app

By Will Duru, BSc (Hons) Sport and Exercise Science, Founder of the 12reps App

I want to tell you a story I’ve seen a thousand times. A woman in her 40s or 50s walks into my gym. She’s motivated, she’s ready to make a change, but she’s completely overwhelmed. She looks at all the equipment and has no idea where to start. So, she does what most people do: a little bit of this, a little bit of that. Some bicep curls, a bit of treadmill, maybe a few crunches. She leaves feeling like she’s done something, but after a few weeks, she’s frustrated because nothing is changing.

This used to be one of the biggest challenges I faced as a personal trainer. How could I give my clients a plan that was simple enough to follow, but effective enough to get them real results? The answer, it turned out, was surprisingly simple. It’s a system that has been around for decades, but it’s often over-complicated and made to sound intimidating. It’s called the Push/Pull/Legs (PPL) split.

I started building all of my clients’ programs around this simple idea, and the results were incredible. They were getting stronger, they were building muscle, and most importantly, they were finally feeling confident and in control of their workouts. This is the exact system that I used as the foundation for my fitness app, 12reps. And the results have been mind-blowing. We’ve had over 2,000 downloads, and we’re approaching 1,000 paying subscribers. We’re generating real revenue, all because we’re giving people a simple, effective plan that works. In this article, I’m going to break down the PPL split for you, just like I do for my clients, and show you how you can use it to finally get the results you deserve.

strength training app

What is Push/Pull/Legs? (The Simple Explanation)

I know that “Push/Pull/Legs” can sound like some kind of complicated bodybuilding jargon. But I promise you, it’s the simplest and most logical way to organise your workouts. Let’s break it down.

Imagine your body has three basic movement patterns:

Pushing: Think about any movement where you are pushing something away from your body. Pushing a door open, putting something on a high shelf, or getting up off the floor. The muscles you use for this are your chest, shoulders, and triceps.

Pulling: Now, think about any movement where you are pulling something towards your body. Opening a car door, starting a lawnmower, or picking up a heavy shopping bag. The muscles you use for this are your back and biceps.

Legs: This one is pretty obvious! It’s everything you do with your lower body. Standing up from a chair, walking up the stairs, or squatting down to pick something up. This uses your quads, hamstrings, glutes, and calves.

That’s it. That’s the entire system. Instead of walking into the gym and just randomly picking exercises, you have a clear focus for each day. On “Push Day,” you only train your pushing muscles. On “Pull Day,” you only train your pulling muscles. And on “Leg Day,” you train your legs. It’s that simple.

12reps- strength training

Why This Works So Well (From My Experience)

For years, I tried different workout splits with my clients. Full body workouts, upper/lower splits, you name it. But nothing has ever worked as consistently as PPL, and I think it comes down to a few simple reasons.

First, it gives your muscles time to recover. This is the big one. When you have a dedicated Push Day, you are working your chest, shoulders, and triceps hard. Then, for the next 48 hours or more, those muscles get to rest and rebuild while you are training your back, biceps, and legs. This is how you get stronger. You don’t build muscle in the gym; you build it when you are resting. PPL has recovery built right into the system.

Second, it allows you to focus. When you walk into the gym and you know it’s Pull Day, you have a clear mission. You’re not trying to do a million different things at once. You can put all of your energy and focus into training your back and biceps. This leads to better quality workouts, and better quality workouts lead to better results. It’s that simple.

Third, it’s incredibly efficient. Because you are working related muscle groups together, you get a lot of bang for your buck. For example, when you are doing a bench press on Push Day, you are not just working your chest; you are also working your shoulders and triceps. This means you can get a great workout in a reasonable amount of time, which is a huge bonus when you are busy.

Don't Forget Your Core! (My Secret Weapon)

If you look at a classic PPL program online, you might notice that something is missing: dedicated core work. This is a huge mistake, in my opinion. Your core—your abs, obliques, and lower back—is the foundation of everything you do. It’s what keeps you stable when you lift heavy things, it’s what protects your spine from injury, and it’s what gives you a strong, confident posture. [1]

I tell all of my clients that a strong core is their secret weapon. That’s why in the 12reps app, we make sure to include core training in every single program. You don’t need to spend hours doing crunches. A few simple, effective exercises at the end of each workout is all it takes. I like to add one or two core exercises to the end of each Push, Pull, and Leg day. This way, you are training your core frequently throughout the week, without making your workouts too long.

How I Structure the Week for My Clients

One of the best things about the PPL split is how flexible it is. You can adapt it to fit your schedule, no matter how busy you are. Here are the two most common ways I set it up for my clients.

The 3-Day-a-Week Plan (The “I’m Super Busy” Option)

This is the perfect starting point. It’s simple, it’s manageable, and it gives you plenty of time to recover between workouts. With this plan, you are hitting every muscle group with high intensity once a week. It’s the perfect way to build a solid foundation of strength.

Monday: Push Day + Core

Tuesday: Rest

Wednesday: Pull Day + Core

Thursday: Rest

Friday: Leg Day + Core

Saturday & Sunday: Rest

The 4-Day-a-Week Plan (The “I Want a Bit More” Option)

Once my clients get comfortable with the 3-day split and they want to take things to the next level, we often move to a 4-day plan. This allows us to hit our muscles a little more frequently. That fourth “Full Body Day” is a great way to add a little extra volume and stimulate more muscle growth without spending hours in the gym. We usually pick one or two key exercises from each of the PPL days and do them together.

Monday: Push Day + Core

Tuesday: Pull Day

Wednesday: Rest

Thursday: Leg Day + Core

Friday: Full Body Day

Saturday & Sunday: Rest

A Sample Plan to Get You Started

To show you how simple and powerful this can be, here is a sample 3-day PPL and core workout that I would give to one of my clients. This is the exact kind of plan you’ll find in the 12reps app. Remember, this is just a starting point. The key is to focus on good form and to try and get a little bit stronger each week.

12reps: The Future of Strength Training and Longevity | Founded by Will Duru

strength training app

My name is Will Duru, and for the last ten years, I’ve been a personal trainer. Every single day, I’ve seen people walk into the gym with the best intentions in the world, only to leave feeling frustrated and defeated. They lack a plan, they don’t know how to use the equipment, and they’re not seeing results. That’s why I built 12reps.

12reps is a mobile app that puts a world-class personal trainer in your pocket, for a fraction of the cost. We use AI to create truly personalised strength training programs that are designed by certified trainers, like me, to help you build muscle, get stronger, and improve your long-term health. The fitness app market is crowded with generic, one-size-fits-all solutions. We are different. We make serious, effective strength training simple and accessible for everyone.

We are here today to ask for a seed round investment to help us scale our user acquisition, expand our development team, and solidify our position as the leading platform for strength training. We are not just building an app; we are building the future of fitness.

12reps: Investing in the Future of Strength Training for Longevity By Will Duru, Founder & CEO

The Problem: The Untapped Potential in Every Gym

I want you to picture someone I call the “Wandering Gym-Goer.” You’ve seen them. They walk into the gym, look around at all the complicated machines, maybe do a few bicep curls, walk on the treadmill for a bit, and then leave. They are trying. They are showing up. But they don’t have a plan. This is the reality for millions of people. They are investing their time and money into their health, but they are getting almost nothing in return. This leads to frustration, a feeling of failure, and eventually, they just give up.

This is a huge problem, but it’s also a huge opportunity. The global fitness app market is a multi-billion dollar industry, projected to be worth over $12 billion in 2025. [1] But it is filled with apps that are all the same. They offer generic workout videos or simple tracking tools that don’t actually help people get results. There is a massive gap in the market for a solution that is intelligent, personalised, and effective.

And the timing for this could not be better. We are at a unique moment where several powerful trends are coming together. First, the world has woken up to the importance of strength training. It is no longer just for bodybuilders. It is now widely recognised by doctors and scientists as one of the most important things you can do for your health and longevity, especially as you get older. [2] Second, AI has reached a point where it can deliver true personalisation at a massive scale. And third, people are looking for authenticity. They are tired of faceless corporations. They want to connect with real experts who they can trust. As a trainer with over a decade of experience and a genuine passion for helping people, I am that expert.

4-Day Push Pull Legs Program for Muscle Gain and Fat Loss | 12Reps app

Our Solution: 12reps - Intelligent Strength Training, Simplified

So, how do we solve this problem? We built 12reps from the ground up to be the solution I always wished I could give my clients. It is built on three core features that make it unlike any other app on the market.

First, we have AI-Powered Personalisation. When you first open the app, it asks you a few simple questions: What are your goals? What equipment do you have access to, whether at home or in a commercial gym? What is your current fitness level? Based on your answers, our AI instantly generates a complete, progressive workout plan that is tailored specifically to you. It’s not a random collection of exercises; it’s a structured program designed to get you results.

Second, we have an Expert-Backed Exercise Library. I personally filmed and wrote the instructions for over 1,500 exercises. Each one comes with a high-quality video demonstration and clear, simple cues to ensure you are performing the movement with perfect form. This is crucial for preventing injury and getting the most out of every single rep.

Third, we have Seamless Progress Tracking. The app makes it incredibly easy to log your sets, reps, and the weights you lift. It then turns that data into simple, beautiful graphs that show you exactly how much stronger you are getting over time. This is the secret to staying motivated. When you can see your progress, you want to keep going.

But our real “secret sauce” is our authenticity. I am not a Silicon Valley tech bro who just saw a market opportunity. I am a trainer who has been in the trenches with real people, helping them overcome these exact struggles for years. We are not targeting teenagers who want to look good on TikTok. We are targeting a motivated and underserved demographic—people in their 30s, 40s, and 50s who are serious about their long-term health. We are giving them the expertise of a personal trainer, which would normally cost hundreds of pounds a month, for just £9.99 a month.

Traction: The Proof is in the Progress

This isn’t just an idea. We have built the product, we have launched it, and the response has been incredible. I didn’t just identify the problem; I lived it with my clients, and then I built the solution myself. And it is working.

In just a few short months, with a tiny marketing budget, we have already achieved over 2,500 downloads. More importantly, we are converting those downloads into loyal, paying customers. We have almost 1,000 active subscriptions, which has already started to generate real revenue. This proves that people are not just willing to try our app; they are willing to pay for it because they see its value and everything is organic 

Our users are not just downloading the app and forgetting about it. They are using it. Our engagement metrics show that a significant percentage of our users are completing at least three workouts per week. They are following the plans, they are tracking their progress, and they are getting stronger. Our user retention is strong, and our App Store ratings are consistently high, with glowing reviews from people who tell us that 12reps has finally given them the confidence and the plan they needed to succeed.

This early traction is the most important signal we have. It shows that we have found a real pain point and that our solution is resonating with our target audience. We have achieved product-market fit. Now, we are ready to scale.

The Ask & The Vision: Building the Global Standard

We are seeking a seed investment to pour fuel on this fire. We want to use this funding to achieve three key goals.

First, User Acquisition. We will scale our marketing efforts to reach a wider audience. We know who our customer is, and we know how to reach them. We will invest in paid social media, collaborations with other trusted fitness influencers, and content marketing to establish 12reps as the go-to resource for strength training.

Second, Product Development. We will expand our small engineering team to make our app even better. We want to enhance our AI capabilities, integrate with popular wearables like the Apple Watch, and build out more community features to connect our users with each other.

Third, Operations. We will hire a few key people to help us manage our growth and provide world-class support to our customers.

Our vision is not just to be another fitness app. Our vision is to become the global standard for strength training. In 24 months, we aim to be the leading app for strength training in the UK and the US, with over 10-20,000 paying subscribers. In 5 years, we plan to expand globally, integrate with connected fitness hardware, and build a comprehensive health platform that also includes nutrition and recovery coaching.

Investing in 12reps is an opportunity to get in on the ground floor of a company that is solving a real problem in a massive, growing market. You are investing in a proven founder with deep domain expertise and a passion for the mission. You are investing in a scalable technology platform that is already showing incredible traction. And you are investing in a company with a clear path to profitability, based on a simple and proven subscription model.

Thank you for your time. I am ready to answer any questions you may have.

3-Day Strength Training Split for Fat Loss | Bala’s 18kg Transformation

Strength Training in Your 30s and 40s: Why Personal Training (Tower Bridge/London Bridge)

By Will Duru, BSc (Hons) Sport and Exercise Science, Award-winning Personal Trainer

I’m Will Duru, and for more than a decade, I’ve had the privilege of guiding people on their journey to a stronger, healthier life. I’ve seen countless transformations, but some stories stick with you. The story of my client, Bala, is one of them. When Bala walked into my gym for the first time, he carried the weight of his goal on his shoulders: to shed 18kg of body fat. He was new to the world of fitness, intimidated by the complex machines and the sea of unfamiliar faces. He needed more than just a workout plan; he needed a clear, simple, and sustainable path to follow. He needed a program that would not only deliver results but also build his confidence and make him feel at home in the gym.

I designed a 3-day push/pull/legs strength training split for him, combined with interval cardio in zone 3 to maximise fat burning. The results were nothing short of amazing. Over the course of 12 months, Bala not only lost the 18kg of body fat he had set out to lose, but he also gained significant strength and built a solid foundation of lean muscle.

In this article, I’m going to share the exact 12-month program I created for Bala. This isn’t just a generic workout plan; it’s a comprehensive guide designed for beginners who are ready to commit to a real change. We’ll break down the workouts, explain the science behind the methods, and give you the tools you need to embark on your own transformation. My promise to you is to keep it simple, direct, and effective. Let’s get started.

The Power of the Push/Pull/Legs Split

The push/pull/legs split is a time-tested, scientifically backed training methodology that has proven effective for individuals of all fitness levels. It’s a simple yet powerful way to organise your training week, and it’s the foundation of the program that led to Bala’s incredible success. Let’s delve deeper into why this split is so effective:

  • Enhanced Focus and Intensity: By focusing on a specific group of muscles each session, you can channel all your energy and focus into them. This allows for a higher level of intensity during your workouts, which is a key driver of muscle growth and fat loss. When you’re not fatigued from working your entire body, you can push each muscle group to its absolute limit, maximising the stimulus for adaptation.
 
  • Greater Training Volume: The push/pull/legs split allows for higher training volume per muscle group than full-body workouts. Volume, calculated as sets x reps x weight, is a critical factor in muscle hypertrophy. By dedicating an entire session to a specific muscle group, you can perform more exercises and sets for that group, leading to greater overall growth.
 
  • Improved Mind-Muscle Connection: With a focused training split, you can develop a stronger mind-muscle connection. This is the ability to consciously feel and contract the target muscle during an exercise. A strong mind-muscle connection ensures the right muscles do the work, leading to better results and a lower risk of injury.
 
  • It’s Simple: You train all your pushing muscles (chest, shoulders, triceps) on one day, your pulling muscles (back, biceps) on another, and your lower body (quads, hamstrings, glutes, calves) on the third day. This makes it easy to remember and follow.
 
  • Optimal Recovery: By splitting your workouts this way, you give each muscle group ample time to recover before retraining it. This is crucial for muscle growth and preventing injuries.
 
  • High Intensity: Because you’re only training a few muscle groups each day, you can hit them with high intensity and volume, which is essential for stimulating muscle growth and burning calories.
12reps app - strength training app

Supercharging Fat Loss with Interval Cardio

To accelerate Bala’s fat loss journey, we strategically incorporated interval cardio into his program. We specifically targeted Zone 3 cardio, which corresponds to an intensity level of 70-80% of your maximum heart rate. This “sweet spot” is highly effective for maximising fat oxidation (i.e., burning fat for fuel). Here’s a closer look at how we implemented this powerful tool:

  • Increased Caloric Expenditure: Interval training is highly effective for burning a significant number of calories in a short time. The intense bursts of effort, followed by brief recovery periods, keep your heart rate elevated and your metabolism revved up, even after your workout is over. This “afterburn” effect, known as excess post-exercise oxygen consumption (EPOC), means you continue to burn calories at an elevated rate for hours after you leave the gym.
 
  • Hormonal Response: High-intensity interval training has been shown to stimulate the release of growth hormone and other hormones that promote fat loss and muscle growth. This hormonal response, combined with the caloric expenditure, creates an optimal environment for body recomposition.
 
  • Time Efficiency: Let’s be honest, we’re all busy. Interval training is a time-efficient way to get a great cardio workout. You can achieve the same, if not better, results in 20-30 minutes of interval training as you would in a longer, steady-state cardio session.
 
  • Treadmill Intervals: We would alternate between periods of high-intensity running and recovery walking. For example, 1 minute of running followed by 2 minutes of walking, repeated for 20-30 minutes.

This type of training is not only effective for fat loss, but it also improves your cardiovascular health and endurance.

Combining 12-Rep Training with Cardio for Optimal Results

Nutrition for Fat Loss: The Missing Piece of the Puzzle

Before we dive into the workout program, it’s crucial to understand that you can’t out-train a bad diet. Nutrition is the cornerstone of any successful fat loss journey. Bala’s transformation was as much about what he ate as it was about how he trained. Here are the key nutritional principles that he followed:

  • Caloric Deficit: To lose fat, you must be in a caloric deficit, meaning you consume fewer calories than you burn. We calculated Bala’s daily caloric needs and created a moderate deficit of about 500 calories per day. This allowed him to lose fat at a steady and sustainable pace without feeling deprived.
 
  • High Protein Intake: Protein is essential for preserving muscle mass while in a caloric deficit. We made sure that Bala was consuming 1.6-2.2 grams of protein per kilogram of his body weight each day. This helped him stay full and satisfied, and it ensured that he was losing fat, not muscle.
 
 
  • Whole, Unprocessed Foods: We focused on a diet rich in whole, unprocessed foods like lean meats, fish, fruits, vegetables, and whole grains. These foods are nutrient-dense and provide the vitamins and minerals your body needs to function optimally.
 
  • Hydration: Staying hydrated is crucial for overall health and performance. Bala aimed to drink at least 3-4 litres of water per day.

By combining a sound nutritional strategy with a consistent training program, Bala achieved his fat-loss goals without resorting to extreme diets or unsustainable practices.

Bala’s 12-Month Transformation Blueprint

This 12-month program is the exact blueprint that Bala followed to achieve his remarkable 18kg fat loss. It’s divided into four distinct 3-month phases, each designed to build upon the previous one. The key to success with this program is consistent progression. As you get stronger and fitter, you must continue to challenge your body by increasing the weight you lift, the number of repetitions you perform, or the number of sets you complete. The 12Reps app is an indispensable tool for tracking your progress and ensuring you’re always moving forward.

Build Muscle with Push/Pull/Legs: Complete 5-Day Training System | 12Reps

Strength Training at 49: It’s Not About Turning Back the Clock, It’s About Winding It Better

 

By Will Duru, BSc (Hons) Sport and Exercise Science, Award-winning Personal Trainer with over 10 years of experience in strength training and optimising recovery.

Build Muscle with Push/Pull/Legs and Core: The Complete 5-Day Training System

If you want to build muscle and get in great shape, the push/pull/legs split combined with core work is the perfect way to do it. This method lets you train 5 days a week with a smart structure that builds muscle while keeping your body fresh. As a personal trainer with over 10 years of experience, I have seen this approach work time and time again for people who want real results.

The push/pull/legs system groups muscles that work together. Push days train your chest, shoulders, and triceps. Pull days work your back and biceps. Leg days build your lower body with functional movements. When you add interval cardio to this mix, you get that lean, defined look with a shaped face. The cardio burns fat while the weights build muscle. But training is only part of the equation. Your nutrition makes or breaks your results.

Nutrition: The Foundation of Muscle Growth

To build muscle, you need to eat right. Your body needs three main nutrients: protein, carbohydrates, and fats.

Protein builds and repairs your muscles. When you lift weights, you break down muscle fibers. Protein fixes them and makes them bigger and stronger. You need about 1.6 to 2.2 grams of protein per kilogram of bodyweight each day. If you weigh 70kg, that is 112 to 154 grams of protein daily. Good sources are chicken, fish, eggs, and lean beef.

Carbohydrates give you energy for your workouts. Without enough carbs, you will feel weak and tired in the gym. Eat oats, rice, sweet potatoes, and fruits. Carbs should make up 35-40% of your daily calories.

Fats help your hormones work properly. Hormones like testosterone are key for building muscle. Get your fats from avocados, nuts, olive oil, and fish. Fats should be 25-30% of your daily calories.

A simple split for building muscle and losing fat:

  • Protein: 30-35%
  • Carbohydrates: 35-40%
  • Fats: 25-30%

Why Strength Training + Running Are Key To Weight Loss and Muscle Building

12reps- strength training

 

By Will Duru, BSc (Hons) Sport and Exercise Science, Award-winning Personal Trainer

If you are 29, this is your window. Your recovery is still solid. Your hormones still support growth. Your habits are forming for the next decade. You can set your body up for lean mass, strong bones, and steady energy.

The simple play is this. Lift with intent. Run with purpose. Track everything in the 12Reps app. Download the free trial and start today.

I will keep this very clear and very practical. No fluff.

The psycho-logic of fat loss and muscle gain

People chase weight loss with only cardio or only diet. It seems logical. Eat less, move more. But your body is not a spreadsheet. It is a nervous system with cravings, pride, fear, and comfort loops.

Here is the move that works in real life.

  • Use strength training to protect and grow muscle while you lose fat. Muscle raises daily energy use and shapes your frame. A large review shows resistance work reduces body fat percentage, fat mass, and visceral fat.
  • Use running or other cardio to push the heart and increase calorie burn. It helps weight control and improves fitness fast when programmed well.
  • Follow the UK guidelines. Aim for at least 150 minutes of moderate activity a week plus muscle-strengthening work on two days. That mix is the baseline for health and weight control.

This pairing beats either one alone for most people. Lift to keep the engine. Run to clear the tank.

The 12Reps Method in simple terms

The 12Reps Method focuses on clear structure and steady overload. It is built around sets of about 12 reps, controlled tempo, and small weekly progress

In the 12Reps app you get:

The method is not magic. It is a consistent practice. Add a little load. Add a rep. Hold your form. Repeat.

 

Strength Training in Your 30s and 40s: Why Personal Training (Tower Bridge/London Bridge)

Why this works for weight loss

  • Muscle is an active tissue. More muscle means higher resting energy use. You burn more throughout the whole day.
  • Lifting preserves lean mass while you eat in a mild deficit. That keeps your metabolism and your shape. A meta-analysis shows resistance training reduces fat mass and visceral fat, which is the dangerous belly fat.
  • Running or brisk cardio helps create a clean calorie gap without cutting food to the bone. Harvard notes running improves cardiovascular fitness quickly, which lets you sustain higher work levels and burn more calories.
  • The NHS guidance confirms the mix. Do your weekly cardio target and also strengthen all major muscle groups at least twice a week.

In short. Keep the muscle. Lose the fat. Feel better doing it.

Why this work for muscle building

  • Mechanical tension plus volume signals growth. Sets of 8 to 12 with good form are a strong base.
  • Progressive overload drives adaptation. Small jumps add up over months.
  • Cardio supports the process. Better aerobic fitness improves recovery between sets and between sessions. You train more productively.
  • Structure matters. A planned strength training split inside a workout planner stops random training and stalls.

 

Pair this with enough protein, solid sleep, and you will add lean mass while staying lean.

About the 12reps App: Your Complete Workout Planner and Tracker 2025 and 2026

Why 29 is the sweet spot

  • You still build fast.
  • You recover well if you manage sleep and food.
  • You can build a “reserve” of muscle and bone before natural decline begins later.
  • You fix posture and movement patterns before desk life sets them in stone.
  • You set routines that carry into your 30s and 40s.

If you are 29, take this year seriously. It pays off for decades.

Mental, physical, confidence, productivity

Mental

  • Lifting gives clear wins. You see progress in numbers. That builds belief.
  • Cardio clears stress and sharpens mood. Even short runs help.
  • Training days create rhythm. Your mind trusts your plan.

Physical

  • Better body composition. More lean mass, less fat. The evidence on resistance training is strong regarding fat and visceral fat reduction.
  • Stronger heart and lungs. You handle stairs, sport, and life with less strain.
  • Fewer aches. Strong tissue supports joints.

Confidence

  • Clothes fit better.
  • Posture improves.
  • You move like someone who takes care of their body.

Productivity

  • Higher energy across the day.
  • Better sleep helps focus.

You learn to set targets and hit them.

A simple weekly plan to copy

Keep it tight. Keep it repeatable. Use the 12Reps app to load this plan and track it.

Day 1

  • Lower-body push and pull
  • Squat pattern, hinge pattern, core
  • 3 to 4 sets of 8 to 12 per move
  • Easy run or brisk walk 15 to 20 minutes to finish

Day 2

  • Easy cardio 30 to 40 minutes at a conversational pace

Day 3

  • Upper-body push and pull
  • Press pattern, row pattern, arms, core
  • 3 to 4 sets of 8 to 12 per move

Day 4

  • Intervals 20 to 25 minutes
  • 1 minute faster, 1 to 2 minutes easy, repeat

Day 5

  • Full-body strength
  • One squat, one hinge, one upper push, one upper pull, one carry
  • 3 sets of 8 to 12

Day 6

  • Optional long easy cardio 30 to 60 minutes

Day 7

  • Rest, mobility, steps

Use the workout tracker to log loads and reps. Use the workout planner to space hard days and rest. If you want structure from day one, load a 6 workout program.

12reps- strength training

How to progress without stalling

  • Add 2 to 5 kg to a lift when you hit the top of the rep range with clean form.
  • If form slips, hold the load and improve the rep quality.
  • Push cardio by adding minutes first, then sprinkle in short intervals.
  • Keep protein high and sleep regular.
  • Every 6 to 8 weeks, pull back volume for one lighter week. Then build again.

This is steady. Not flashy. It works.

Quick checklist

  • Lift two to four days a week.
  • Run or do cardio two to four days a week.
  • Hit the NHS targets for movement and do strength work for all major muscle groups.
  • Track everything in the 12Reps app.
  • Use a strength training split and a workout planner.
  • Keep faith with the process for 12 weeks.

Why Strength Training Is Key to Weight Loss & Muscle Building — And How 12Reps Makes It Work

strength training app

By Will Duru, BSc (Hons) Sport & Exercise Science, Award-winning Personal Trainer

If you’re 29 (man or woman), this is the moment to unlock change. Strength training isn’t just for bodybuilders. It’s your secret weapon: burn fat, build muscle, sharpen your mind, boost confidence, and get productivity on your side. Use the 12Reps app (try free trial) to guide you.

What weight loss really means — and why lifting matters

Most people think weight loss is about eating less and doing more cardio. That’s logic. But psycho-logic: your body fights back. You lose muscle, your metabolism slows, you feel drained.

Strength training flips the script.

  • It increases your basal metabolic rate (BMR). Muscle burns more energy than fat, even when you’re resting.
  • It preserves lean mass while you cut calories. Studies show resistance training reduces lean mass loss when dieting.
  • It triggers “afterburn” — extra calorie burn post-workout as your body recovers.
  • It shrinks visceral fat (dangerous belly fat) more than aerobic work alone.
  • It changes your body composition: you may not see huge weight drops, but fat falls off, and muscle fills in. You look sharper, leaner.

A major review found that exercise interventions resulted in an average weight loss of 4 kg and meaningful reductions in fat and visceral fat.  So strength training is not optional. It is central.

12reps app - strength training app

What is the 12Reps method & why it helps

The 12Reps method (via the 12Reps app) blends structure, progression, recovery — all the pieces that often get ignored. The app is often called “build muscle, lose fat” for a reason. 

Key features:

  • There is enough volume and intensity to stimulate both strength and hypertrophy.
  • Programmable rest and recovery to avoid overtraining.
  • Progressive overload (you increase load, reps over time).
  • Tracking allows you to see your progress, reps, weights, and consistency.
  • Balanced splits, so you don’t overwork some muscles and neglect others.

Because 12Reps organises your strength training into smart plans (workout planner, strength training split, 6 workout program), you get structure instead of chaos. You need that when you begin.

12reps app - strength training app

Why, at age 29, you should care

  • Your muscle mass naturally begins to decline if unused.
  • Your recovery windows are still good. You can build faster now than later.
  • Hormones, metabolism, bone density are still flexible.
  • You can build a “reserve” so when life stress, ageing, or injury hits you, you have a buffer.
  • Starting now gives compounding effects. A 5-year head start on strength is huge.

Don’t wait until you feel “old.” Begin now.

Building muscle — the key to aesthetics + function

Muscle is not just cosmetic. It’s functional, hormonal, and metabolic.

  • Through resistance, you apply tension and micro-damage, allowing your body to repair itself more strongly.
  • The principle of progressive overload is your engine.
  • With the 12Reps app, you can plan your strength training split to ensure every muscle gets work and recovery.
  • You feed muscle with good protein and rest.
  • Muscle improves insulin sensitivity, glucose uptake, and reduces disease risk.
  • More muscle = more daily calorie burn = better ability to lose fat without decaying lean tissue.
12reps- strength training

The full transformation: mental, confidence, productivity, Mental & emotional shift

There is a hidden psychology in lifting. When you pick up a heavy bar, you win small battles. Day after day, you see incremental wins. That feels different from passively running on a treadmill.

Strength work releases endorphins and improves mood, reduces anxiety and depression. Multiple reviews support this. 

Your brain senses capability. You feel powerful.

Confidence & presence

Your body changes: posture straightens, shoulders back, core firm. People notice. You feel more grounded in your body.

You carry an internal certainty: “I can get stronger.” That mental posture spreads into your work, your speech, your goals.

Productivity & adult life

  • You have more energy.
  • Fewer aches, fewer days off.
  • When you face stress, your body is resilient.
  • You become disciplined, and you apply that to business and relationships.
  • Because training is measurable, you’re used to setting goals, tracking progress — this habit translates.

If your 20s are about building identity, strength training builds identity through your body.
