The Claim
Does full range of motion build bigger glutes and adductors than partial range?
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.
When you squat or move your legs widely, your butt and inner thighs grow more than if you only do the last bit of the movement.
See the scientific wording
Full range of motion is associated with greater hypertrophy in the gluteus maximus and adductors compared to partial range of motion performed in the final part of the movement, with between-group effect sizes of 0.24–0.25.
What the research says
1 studyStudy: Which ROMs Lead to Rome? A Systematic Review of the Effects of Range of Motion on Muscle Hypertrophy
The study found that doing full squats or similar movements (full range of motion) builds more glute and inner thigh muscle than only doing part of the movement at the bottom, which is exactly what the claim says.
