When it comes to resistance training, the proper range of repetitions is dictated by our goals. We can train for strength, muscle growth, or muscular endurance.
Strength rep ranges: 1-5
Muscle growth rep ranges: 6-12
Muscular endurance rep ranges: 12-20
No matter our goal or which repetition range we’re using, the key is to train at the heaviest resistance possible, with good form, for all repetitions.
