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.
Also targets: Quadriceps, hip adductors, Hamstrings

We slot it into the right day with sets, reps, and progression you can follow.
Stand with feet significantly wider than shoulder-width apart.
Keep your toes pointing forward or slightly outward.
Shift your weight to one side bending that knee deeply.
Keep the opposite leg completely straight with foot flat.
Lower as deep as your mobility allows on the bent side.
Push through the bent leg to return to center and repeat.
Great exercise for improving hip and ankle mobility.
Keep your chest up and back flat throughout.
Your straight leg heel should stay on the ground.
Start with limited depth and progress gradually.
Program Cossack squats for hip mobility development, lateral strength, or when you want squat variation that challenges different movement patterns. Use moderate reps per side with focus on depth. They pair well with traditional bilateral squats.
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.
Intermediate lifters working on mobility and lateral strength.
Lower reps with heavier weight builds raw strength. Your muscles and nervous system adapt to handle more load over time. This range is best for strength-focused goals.
This rep range keeps your muscles under tension long enough to trigger growth. Most people see the best muscle-building results in this zone. It balances strength and muscle size.
Higher reps with lighter weight builds muscular endurance and improves conditioning. This range is good for joint health and building work capacity.
General guideline: 3 sets of 8-10 reps per side. Rest 60 seconds.
