High-bar narrow stance squats increase knee extensor demand (greater knee contribution to total moment and higher vastus lateris activity) compared to low-bar wide 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 an HBNS resulted in greater knee contributions to the total moment together with higher vastus lateralis and less gluteus maximus myoelectric activity. Our findings suggest that training with an HBNS could be beneficial when targeting the knee extensors and plantar flexors
