Cossack Squat
cossack-squat
When I guide you through this movement, you will feel a deep, satisfying stretch opening across your inner thighs and hips. Good reps feel fluid and grounded, like a slow, controlled wave shifting from side to side. I love how your chest stays proud and your breathing stays steady, while each descent teaches your joints to move with quiet confidence. It is pure mobility in motion, leaving you wonderfully open, balanced, and ready.
If you're new to this
Start with a narrower stance and a shallower range until your hips and ankles adapt to the lateral demand. Keep your weight centered over the midfoot of the bending leg, never letting your knee cave inward past your toes. If you feel sharp pinching in the groin or a sudden loss of balance, stop immediately and reduce your depth. Beginners often compensate by rounding the lower back or lifting the heel of the working foot to force a deeper position; instead, keep that heel grounded and hinge from the hips. You might also notice the straight leg bending slightly at the knee to avoid the stretch. That is completely normal in the beginning. Allow the extended leg to remain straight but soft, letting the floor do the work. Breathe continuously and never push through joint pain. Progress gradually, adding only a few inches of depth each week as your tissues adapt. Trust the process, stay patient with your mobility, and let consistency build the foundation for a fluid, controlled movement.
Common mistakes
Most practitioners rush the descent, sacrificing control for depth and allowing the working knee to collapse inward under the load. This valgus drift places unnecessary stress on the ligaments and robs the glutes of their stabilizing role. Another frequent error is lifting the heel of the planted foot, which shifts the center of gravity forward and turns a hip-dominant pattern into a quad-heavy squat. You will also see people forcefully push the straight leg into the ground, creating tension rather than allowing a passive, relaxed stretch. Finally, many forget to engage the core, resulting in a rounded spine and excessive lumbar flexion as they drop into the bottom position. Slow the tempo, prioritize a flat foot, and let the stretch happen naturally without muscular resistance.

Equipment
- Bodyweight
- 1
Stand with feet wider than shoulder-width apart and angle the toes slightly outward.
- 2
Engage the core muscles and lengthen the spine to maintain a tall torso.
- 3
Shift weight smoothly to the right side while bending the right knee and tracking it over the toes.
- 4
Inhale deeply as the hips lower toward the right heel, keeping the left leg fully extended.
- 5
Keep the left heel grounded and point the left toes upward to stretch the inner thigh.
- 6
Maintain a neutral spine and prevent the chest from collapsing forward during the descent.
- 7
Push firmly through the right foot while exhaling to drive the body back to the center.
- 8
Return to an even weight distribution across both feet and reset posture before alternating sides.
