How to Build Muscle Mass: A Scientific Guide to Hypertrophy

Muscle hypertrophy occurs when muscle protein synthesis exceeds muscle protein breakdown. For this, you need three essential factors:

• Mechanical stress - progressive resistance training
• Protein surplus - amino acids for rebuilding
• Recovery - adequate sleep and rest

Studies show that muscles can grow by 0.25-0.5 kg per month for beginners (less for advanced trainees).

Caloric surplus: You need 300-500 calories above your maintenance needs.

Protein: 1.6-2.2g per kg body weight daily, distributed across 4-5 meals.

• Chicken, turkey, lean beef
• Fish (salmon, tuna, mackerel)
• Eggs (whole, not just whites)
• Dairy (cottage cheese, Greek yogurt)
• Legumes (lentils, chickpeas, beans)

Carbohydrates: The fuel for intense workouts.

• Rice, potatoes, whole wheat pasta
• Oats, whole grain bread
• Fruit post-workout

Fats: 0.8-1g per kg body weight for optimal hormones.

Optimal parameters for muscle growth:

• Volume: 10-20 sets per muscle group per week
• Reps: 6-12 reps for most exercises
• Frequency: Each muscle twice per week
• Progression: Increase weight or reps weekly

Example Push/Pull/Legs split:

• Monday: Push (chest, shoulders, triceps)
• Tuesday: Pull (back, biceps)
• Wednesday: Legs (legs, glutes)
• Thursday: Rest
• Friday-Sunday: Repeat the cycle

Muscles grow during rest, not in the gym. Neglecting recovery is the most common mistake.

Sleep: 7-9 hours per night. During deep sleep, the body releases growth hormone (GH).

Rest days: 1-2 days without training per week.

Stress: Chronic cortisol inhibits protein synthesis. Manage stress through meditation, walks, or hobbies.

Hydration: Muscles are 70% water. Drink at least 2-3 liters daily.

Supplements are not mandatory, but they can help:

Creatine monohydrate - the most studied supplement, safe and effective. 3-5g daily.

Whey protein - convenient for hitting your protein target, not magical.

Vitamin D - important for health and performance, especially in northern climates.

Omega-3 - anti-inflammatory and beneficial for recovery.

Note: Supplements represent at most 5% of results. The focus should be on nutrition, training, and rest.
