Key Benefits of Muscle Building:
- Increased resting calorie burn through higher lean muscle mass
- Improved posture through better strength balance
- Enhanced strength, coordination, and balance
- Better bone density and reduced bone loss
Muscle Growth Fundamentals: Hypertrophy occurs when strength training creates microscopic muscle fiber tears. As these tears repair, muscles grow larger through consistent training.
Workout Frequency and Volume:
- Train each muscle group 2-3 times per week
- Perform 3-4 sets of 8-12 reps per exercise
- Use weights that make the last 2-3 reps challenging
- Implement progressive overload by gradually increasing weight, reps, or intensity
Equipment Choice:
- Machines: Ideal for beginners, fixed movement path, safer for heavy weights
- Free weights: Better for advanced lifters, engages more stabilizing muscles

Weekly strength training split schedule
Workout Splits: Popular options include:
- Push/Pull/Legs (6-day split)
- Chest & Back/Legs/Shoulders & Arms (3-1-3 split)
- Back & Biceps/Chest & Triceps/Legs/Shoulders (4-day split)
Nutrition Requirements:
- Eat in a 5-10% calorie surplus
- Consume 1.4g protein per kg bodyweight
- Focus on lean meats, eggs, legumes, and dairy
- Include pre-workout carbohydrates for energy
