strength training app

Introduction

Are you a beginner looking to pack on serious muscle? Have you set yourself the ambitious goal of gaining 10kg of lean muscle in the next 12 months? If so, you’ve come to the right place. My name is Will Duru, and with over a decade of experience in strength training, I’m here to guide you on your journey. This article will provide you with a comprehensive 5-day strength training split designed to help you build muscle, get stronger, and achieve the physique you’ve always wanted. We’ll delve into the principles of progressive overload, the importance of nutrition and recovery, and provide you with a detailed 12-week program to get you started. Plus, we’ll introduce you to a powerful tool to track your progress: the 12Reps app.

The Importance of a Structured Training Split

When it comes to strength training, having a structured plan is paramount. A well-designed training split ensures that you’re working all your major muscle groups effectively, while also allowing for adequate recovery time. This is crucial for muscle growth, as it’s during rest periods that your muscles repair and rebuild themselves stronger than before. Our 5-day split focuses on a push/pull/legs methodology, a proven system for building a balanced and athletic physique.

Nutrition for Muscle Growth

Nutrition plays a massive role in building lean muscle mass while keeping body fat low. To build muscle, you need to consume a surplus of calories, meaning you need to eat more calories than your body burns. However, the quality of these calories is crucial. Your diet should be rich in protein, complex carbohydrates, and healthy fats.

Here’s a sample macronutrient breakdown for a 70kg individual looking to put on muscle:

  • Protein: Aim for 1.6-2.2g of protein per kg of body weight. For a 70kg person, this would be 112-154g of protein per day. Protein is the building block of muscle tissue, so it’s essential for repair and growth. Good sources include chicken, fish, eggs, dairy, and legumes.
  • Carbohydrates: Carbs are your body’s primary source of energy. Aim for 4-7g of carbs per kg of body weight. For a 70kg person, this would be 280-490g of carbs per day. Focus on complex carbohydrates like oats, brown rice, and sweet potatoes for sustained energy.
  • Fats: Healthy fats are important for hormone production and overall health. Aim for 0.5-1g of fat per kg of body weight. For a 70kg person, this would be 35-70g of fat per day. Good sources include avocados, nuts, seeds, and olive oil.

Sleep and Recovery

Sleep is when the magic happens. During deep sleep, your body releases growth hormone, which is essential for muscle repair and growth. Aim for 7-9 hours of quality sleep per night to optimise your recovery and ensure you’re ready for your next training session.

The Ultimate 5-Day Muscle-Building Split: My Proven Path to 8kg of Muscle

The Ultimate 5-Day Muscle-Building Split: My Proven Path to 8kg of Muscle

Hi, I’m Will Duru, a personal trainer with over a decade of experience in helping people like you achieve their fitness goals. I hold a degree in Sport and Exercise Science, and I’m passionate about using my knowledge to create effective and sustainable training programs. Today, I’m excited to share with you the exact 5-day training split that helped me gain 8kg of lean muscle. This isn’t just about lifting weights; it’s about a holistic approach that combines smart training, proper nutrition, and consistent effort.

The Foundation: Progressive Overload Explained

If there’s one principle that has been the cornerstone of my success and the success of my clients, it’s progressive overload. In simple terms, progressive overload means continually increasing the demands on your muscles to stimulate growth. You can’t expect to get stronger or build muscle if you’re always lifting the same weight for the same number of reps. Your body is smart; it adapts. To keep making progress, you have to give it a reason to adapt.

This doesn’t mean you have to go to failure on every set, but it does mean you need to challenge yourself. Whether it’s adding a little more weight, doing one more rep, or reducing your rest time, the key is to consistently push your limits. This is a principle I’ve applied with great success, not just for myself but also for my female clients. I’ve seen firsthand how lifting heavy weights can transform a woman’s body, helping them build lean muscle, burn fat, and sculpt a strong, confident physique. It’s a myth that lifting heavy weights will make women bulky. The truth is, it’s the most effective way to achieve that toned, athletic look that so many desire. You can read more about how I apply this in my article on The Science of Progressive Overload.

Fueling Your Gains: The Nutrition Blueprint

Training is only half the battle. To truly maximise your muscle-building potential, you need to fuel your body with the right nutrients. Think of your body as a high-performance car; you can have the best engine in the world, but if you put in low-quality fuel, it’s not going to perform at its best. The same goes for your body. Here’s a breakdown of the macronutrients you need to focus on:

Protein: The Building Block

Protein is the most important macronutrient for muscle growth and repair. When you lift weights, you create microscopic tears in your muscle fibres. Protein provides the amino acids your body needs to repair these tears and build your muscles back stronger. I recommend consuming around 1.6-2.2 grams of protein per kilogram of body weight. For an 80kg individual, that’s about 128-176 grams of protein per day.

Good sources of protein include:

  • Lean meats (chicken, turkey, beef)
  • Fish (salmon, tuna, cod)
  • Eggs
  • Dairy products (Greek yogurt, cottage cheese)
  • Protein supplements (whey, casein)

Carbohydrates: Energy for Performance

Carbohydrates are your body’s primary source of energy. They fuel your workouts and replenish your glycogen stores after training. Don’t be afraid of carbs; they are essential for performance and recovery. I recommend consuming around 4-6 grams of carbohydrates per kilogram of body weight. For an 80kg individual, that’s about 320-480 grams of carbohydrates per day.

Good sources of carbohydrates include:

  • Oats
  • Rice
  • Potatoes
  • Fruits
  • Vegetables

Fats: Essential for Health and Hormones

Fats often get a bad rap, but they are essential for overall health and hormone production. Healthy fats help regulate your hormones, including testosterone, which plays a crucial role in muscle growth. I recommend consuming around 0.8-1.2 grams of fat per kilogram of body weight. For an 80kg individual, that’s about 64-96 grams of fat per day.

Good sources of healthy fats include:

  • Avocados
  • Nuts and seeds
  • Olive oil
  • Fatty fish (salmon)

To make tracking your nutrition easier, I highly recommend using the 12Reps app. It takes the guesswork out of nutrition and helps you stay on track with your goals. And for my female clients, I have a specific guide on how to build strength and confidence with a proper weight training routine, which you can find here: Woman’s Weight Training Routine Guide for Beginners.

My 5-Day Muscle-Building Split: The Workout

This 5-day split is designed to effectively target each major muscle group, allowing for adequate recovery while maximising growth. Remember, the key is progressive overload – aim to improve each session by adding weight, increasing reps, or refining form. Each exercise includes a warm-up set, followed by 4 working sets with reps between 8-12. The intensity should be challenging, meaning the last few reps of each set should feel difficult to complete.
