Mixed
Low-bar wide stance squats increase hip extensor demand (greater hip contribution to total moment and higher gluteus maximus activity relative to high-bar narrow stance) compared to high-bar narrow stance squats.
If you want to prioritize your quads, use a high-bar narrow stance. If you want to prioritize your hips and glutes, switch to a low-bar wide stance. These technical changes directly shift the mechanical load to the target muscles.
GoodSupportsHIGH confidence
squatting with a low-bar wide stance condition resulted in larger hip contributions to the total moment than the other squat conditions... Our findings suggest that... a low-bar wide stance could be beneficial when targeting the hip extensors.
Why this rating
Controlled within-subjects design with 18 participants, rigorous biomechanical measurement (inverse dynamics, EMG), but small sample size.
