The Claim

In well-trained individuals, performing lengthened partial range-of-motion resistance training to failure results in similar muscle hypertrophy of the biceps and triceps compared to full range-of-motion training when matched for effort.

Support is ahead, but a single strong opposing study can change this.

In plain English

If you're already fit, doing bicep and tricep exercises through a shorter range of motion—but pushing to your max—can build muscle just as well as doing full reps.

What the research says

2 studies
  1. Study: Lengthened Partial Repetitions Elicit Similar Muscular Adaptations as a Full Range of Motion During Resistance Training in Trained Individuals

    The study found that doing certain types of partial arm exercises that stretch the muscle works just as well as full arm curls for building muscle in trained people.

  2. Study: Lengthened partial repetitions elicit similar muscular adaptations as full range of motion repetitions during resistance training in trained individuals

    The study found that doing certain types of partial arm exercises that stretch the muscle works just as well as full arm movements for building muscle size in trained people.
