The actual activity of resistance training is only half the proverbial battle when it comes to building muscle mass. It is through one's nutrition that the muscle fibers are rebuilt thicker and stronger ultimately leading to muscular hypertrophy. Eating a balanced diet consisting of high protein (around 1 gram of protein per 2.2lbs of bodyweight), moderate low glycemic carbohydrates centered around times of peak insulin sensitivity to prevent minimal storage and low fats in conjunction with a 3 day per week weight training program focusing on progressive overload will build a lean, muscular physique over time.
Here is a sample diet to follow for the average male weight trainer:
1. Breakfast:
4 egg whites, 1 piece of whole wheat toast, 1 banana
2. Snack
1 Apple with 1 tbsp peanut butter
3. Lunch
4-6 ounces of boneless, skinless chicken breast with a green salad
4. Pre-Workout Snack
1/2 cup steel cut oats
5. Post-Workout Snack
1 Apple
25g whey protein isolate
6. Dinner
4-6 ounces of tilapia with grilled asparagus
7. Dessert
1 sugar free fat free jello pudding
