This rep range keeps your muscles under tension long enough to trigger growth. Most people see the best muscle-building results in this zone. It balances strength and muscle size.

Endurance15-20 reps

Higher reps with lighter weight builds muscular endurance and improves conditioning. This range is good for joint health and building work capacity.
