The Claim

Multi-exercise resistance training protocols that combine lengthened partial and full range of motion repetitions produce comparable muscular hypertrophy, with neither training approach demonstrating a clear advantage over the other in experienced lifters.

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

What the research says

Supports is higher

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

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

Cause and effect
1 study reviewed
In plain English

If you mix full-range lifts with partial reps that stretch the muscle, you'll build muscle just as well as if you only do full-range lifts. It doesn't matter which way you train your upper body, as long as you're consistent.

See the scientific wording

Multi-exercise resistance training protocols that incorporate both lengthened partial and full range of motion repetitions produce comparable muscular adaptations. This finding suggests that previous single-exercise studies may not fully represent typical training routines in experienced lifters. By utilizing four distinct exercises per session targeting upper-body musculature, the study demonstrates that ecological validity is maintained while confirming that neither training approach offers a clear hypertrophic advantage over the other.

What the research says

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

    The study found that using partial reps with a stretched muscle or full-range reps results in the same muscle growth and strength gains when done in a typical workout routine with multiple exercises.
