for muscle building, this is what I do:
3 days of weight lifting:
day 1:
biceps and triceps. 4 exercises for each muscle group
day 2:
Chest and back. 4 exercises each muscle group
Day 3:
shoulders and lower body. 4 ecercises each muscle group.
sets, weights, order, and types of excercies change every 2-3 weeks. I do one day of 1 hour cardio, but I hate cardio so I'm guilty of skipping on it a lot.
Take whey protein before and after workouts, plus other supplements like Creatine.
