Which structures should be facilitated or strengthened to improve single-leg squat performance?

• A. Hamstrings and calves
• B. Glute med and single leg bridge
• C. Core stability only
• D. Adductor strength

Answer: (B)

Pelvic and hip stability drives a solid single-leg squat. The gluteus medius is the main hip abductor that keeps the pelvis level on the stance leg and helps prevent the knee from collapsing inward as you descend. Strengthening this muscle, along with hip extension through targeted work like a single-leg bridge, builds the neuromuscular control and strength needed to maintain proper alignment during the movement.

The single-leg bridge is effective because it directly loads the glutes in a hip-extension pattern while challenging the pelvis to stay stable, which translates to better control during the squat. While hamstrings and calves contribute to overall movement, they don’t address hip-side stabilization as effectively. Core stability matters for trunk control, but without robust hip abductor strength, pelvis and knee alignment during a single-leg squat can still be compromised. Adductor strength helps medial stabilization but doesn’t replace the key role of the glute medius in keeping the pelvis level and the knee aligned.
