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.
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.
