Deep squats grew the glutes about three times more than half squats in one study.
Kubo et al., 2019 · Trial: Full squats grew the glutes (+6.7% vs +2.2%) and adductors (+6.2% vs +2.7%) more than half squats. Quad growth was similar. (17 untrained men; 10 weeks.)
Plotkin et al., 2023 · Trial: Hip thrusts and squats grew the glutes similarly over 9 weeks; squats also grew the quads and adductors more. (Untrained participants; wide confidence intervals for glute growth.)
