The Claim

Partial-range-of-motion resistance training produces muscle hypertrophy that is equivalent to that produced by full-range-of-motion resistance training in human subjects.

What the research says

Supports is higher

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

Challenges

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

In plain English

Lifting weights through a shorter movement range can build muscle just as well as lifting through a full movement range — no difference in muscle growth.

Partial-range-of-motion resistance training produces muscle hypertrophy equivalent to full-range-of-motion training in humans.

What the research says

4 studies

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

    This study found that lifting weights through only part of the motion (but stretching the muscle) built muscle just as well as lifting through the full motion — so you don’t need to go all the way down or up to get strong and big muscles.

  2. Study: The effects of lengthened-partial range of motion resistance training of the limbs on arm and thigh muscle area: A multi-site randomised trial

    This study found that lifting weights through a shorter range of motion built muscle just as well as lifting through the full range — so you don’t need to go all the way down or up to get strong and muscular.
