The Cossack Squat

A deep unilateral squat emphasizing hip mobility and lower body strength, particularly useful for practitioners seeking to improve multi-planar movement.

Functional Strength (Pavel Tsatsouline, Dan John) · Originating from traditional Eastern European martial arts and folk dance, the Cossack Squat has been popularized in modern strength and conditioning by figures like Pavel Tsatsouline for its benefits in hip flexibility and lower body resilience. · Restricted hip mobility, lower body strength imbalances, dynamic movement preparation. · 3-5 sets of 5-8 repetitions per side. Perform slowly and with control, emphasizing the deepest comfortable range of motion. Rest 60-90 seconds between sets.

Why it works

The Cossack Squat deeply mobilizes the adductors, hamstrings, and hip flexors of the bent leg, while simultaneously strengthening the glutes and quadriceps of the squatting leg. The unilateral nature challenges balance and proprioception. Applying tension through bracing (as popularized by Hardstyle methodologies) creates global stability, integrating the core with the lower kinetic chain. This sustained tension under load signals safety to the nervous system, allowing for greater range of motion over time as the body perceives less threat in stretched positions. The controlled eccentric and concentric phases enhance tissue resilience.

How to practice

1. Stance: Stand with feet significantly wider than shoulder-width, toes pointed slightly outward (approx. 45 degrees). Keep your chest upright.

2. Initiate: Shift your weight to one side, bending the knee of that leg while keeping the other leg straight. Your heel on the bent-leg side maintains contact with the ground.

3. Descent: Squat down as deep as comfortably possible, aiming to bring your hips below parallel. The straight leg should remain fully extended, with the heel either on the ground or lifted, depending on flexibility.

4. Brace: As you descend, take a large breath into your abdomen, bracing your core as if preparing to receive a punch. Maintain this intra-abdominal pressure throughout the movement.

5. Ascent: Drive through the heel of the bent leg, maintaining core tension, to return to the starting wide stance. Exhale upon reaching the top.

6. Alternate: Repeat the movement on the opposite side.
