What is a key mobility requirement for a safe squat?

• A. Ensure spine stays in constant flexion
• B. Keep torso vertical with no movement
• C. Ensure mobility in ankle, knee, and hip
• D. Rely solely on ankle mobility

Answer: (C)

A safe squat depends on adequate range of motion across several joints, not just one area. Specifically, you need enough mobility in the ankle to allow the knee to move forward over the toes without the heel lifting, in the knee to bend smoothly in line with the toes as you descend, and in the hip to allow the hips to sit back and down while the spine stays neutral. When these joints move well together, you can reach depth and maintain proper alignment, which supports stable loading and reduces the risk of injury.

If ankle mobility is limited, you’ll often compensate by leaning forward excessively, lifting the heels, or rounding the back. If knee or hip mobility is restricted, depth and form suffer, and you may see knee valgus or loss of stability. Relying only on ankle mobility won’t address the other required ranges, and trying to keep the torso rigid or vertical with no movement isn’t realistic or safe for everyone.
