In brief: Fatigue the muscle
Repetitions performed to muscle failure ultimately help the muscles strengthen and grow.
High reps (12-15 per set) for definition, moderate reps (6-8 per set) for size, and low reps (2-4 per set) for strength. Remember, if you get to this target number easily, you're not working the muscles hard enough to achieve a benefit.
