Cossack Squats
Cossack Squats Exercise Description
The Cossack squat is a bodyweight lateral squat that shifts your center of mass side to side to train the lower body in the frontal plane. You lower over one leg while keeping the opposite leg straight, building strength and control through the quadriceps and gluteus maximus of the squatting side, with strong involvement from the hip adductors and abductors for stability. The movement also challenges hip, knee, and ankle mobility, particularly adductor length on the straight leg and dorsiflexion on the squatting leg. Proper execution emphasizes a neutral spine, a flat foot on the working side, and the knee tracking in line with the toes. This exercise is useful for developing unilateral control and range of motion for lateral movements while reinforcing consistent lower-limb alignment.

How To Do The Cossack Squats Exercise
‘- Stand tall with a wide stance; toes slightly turned out within your comfortable hip range.
– Brace your trunk and set a neutral spine with the ribcage stacked over the pelvis.
– Shift your hips back and toward one side, bending that knee as you sit down; keep the other leg straight.
– Keep the squatting foot flat; let the knee track over the middle of the foot without collapsing inward.
– On the straight leg, keep the heel on the floor and lift the toes up as tolerated to encourage adductor stretch.
– Maintain your chest generally upright without rounding; use your arms forward as a counterbalance if needed.
– Descend only as low as you can while keeping the heel down, spine neutral, and knee aligned with the toes.
– Drive through the midfoot/heel of the squatting leg to stand, fully extending the hip and knee.
– Return to center under control, then repeat to the other side.
– Common faults to avoid: heel lift on the working leg, twisting the pelvis, knee valgus, and rushing the transition between sides.

Cossack Squats Beginner Introduction
The Cossack squat is a bodyweight side lunge pattern that shifts weight from one leg to the other in a wide stance. One leg bends and carries most of the load while the opposite leg stays long, creating a strong challenge for the thighs and glutes on the working side. At the same time, the inner thighs and outer hips contribute a great deal to balance and control as the body travels laterally.
Because the movement explores depth over one leg, it also places a spotlight on hip, knee, and ankle flexibility. The straight leg experiences a noticeable stretch through the inner thigh, while the supporting side demands solid ankle bend and stable contact with the floor. Upright posture and steady leg alignment are central themes, with the chest staying lifted and the working knee following the line of the foot. As a result, this exercise serves well for training each side of the lower body separately, building confidence in sideways motion and consistent lower-body mechanics.
