The Cossack squat shifts your weight to one side and drops into a deep single-leg squat while the other leg stays straight, combining strength work with serious hip and ankle mobility demands. This lateral squat pattern develops side-to-side strength that bilateral squats do not provide.
When to use it
Use for mobility training or as a leg exercise variation.
Who it's for
Intermediate lifters working on mobility and lateral strength.
Take a wide stance and shift your weight to one side, bending that knee deeply while keeping the opposite leg completely straight. Your straight leg heel should stay on the floor. Go as deep as your mobility allows while keeping your chest up and back flat.

Common Cossack Squat mistakes
Letting the heel of the bent leg rise.
Your foot position during the Cossack Squat determines how force transfers through your body. Keep your feet flat with weight distributed evenly — losing contact with the ground means you're losing power and stability.
Rounding the lower back during the descent.
A compromised back position during the Cossack Squat puts your spine under unnecessary shear force. Brace your core and maintain a neutral spine throughout the movement.
Not going deep enough to challenge mobility.
Squatting patterns like the Cossack Squat load your entire lower body. This mistake shifts that load to structures that weren't designed to handle it. Stay controlled and let your Glutes (gluteus maximus) absorb the work.
