The anatomy of the Pistol Squat (Step-by-Step Progression) 3D anatomy

The pistol squat exercise is different and more complex than the single-leg squat. Aside from the strength needed to raise the whole body on one leg, high mobility in the ankle and flexible hamstrings are necessary. The main active muscles are the same as those in the squat. The quadriceps extends (straightens) the knee, the gluteus maximus extends the hip, and the gastrocnemius perform plantar flexion in the ankle.
