Kettlebell Cossack Squat

Muscles worked

Setup

1. Hold a kettlebell by the horns in a goblet position, tucked tight against your chest with elbows pointing down.
2. Assume a very wide stance, roughly double shoulder-width apart, with toes pointed slightly outward.
3. Engage your core and pull your shoulder blades back to create a stable shelf for the weight.

How to do it

1. Inhale and shift your weight to one side by hinging your hips back and bending that knee, while keeping the opposite leg perfectly straight.
2. Lower your hips as deep as mobility allows, ideally until the thigh is below parallel, while allowing the toes of the straight leg to pivot upward toward the ceiling.
3. Exhale and drive forcefully through the heel of the bent leg to return to the center standing position.
4. Alternate sides by repeating the movement on the opposite leg, maintaining a controlled and fluid tempo.

Form checklist

• Keep the heel of the working (squatting) foot flat on the floor at all times.
• Maintain an upright chest and neutral spine; do not let the kettlebell pull your torso forward.
• Ensure the knee of the working leg tracks directly over the toes, avoiding internal collapse.
• Keep the non-working leg fully extended with the knee locked to maximize the adductor stretch.

Pro tips

• Think about 'pulling' your pelvis down into your hip socket on the working side to engage the deep hip stabilizers.
• Pause for one second at the bottom of the movement to maximize the stretch-shortening cycle and improve active mobility.

Make it harder

• Implement a 'low-switch' variation where you transition from side to side while staying in the bottom of the squat instead of standing up.
• Increase the eccentric challenge by taking 3-4 seconds to lower into the squat.
