Barbell Cossack Squat

Muscles worked

Setup

1. Position a barbell across your upper traps and stand with an extra-wide stance, roughly double shoulder-width.
2. Point your toes slightly outward and brace your core to create a rigid torso.
3. Grip the bar firmly and pull it down into your shoulders to ensure the load remains stable during the lateral shift.

How to do it

1. Inhale and shift your weight to one side, squatting deeply into that hip while keeping the opposite leg perfectly straight.
2. As you descend, allow the toes of the straight leg to pivot upward toward the ceiling, resting on the heel of that foot.
3. Exhale and drive through the heel and mid-foot of the bent leg to return to the starting wide-stance position.
4. Alternate sides for each repetition, maintaining a controlled 2-1-2 tempo (2 seconds down, 1 second pause, 2 seconds up).

Form checklist

• Keep the heel of the working leg firmly planted on the ground throughout the entire rep.
• Maintain a proud chest and upright spine to prevent the barbell from pulling your torso forward.
• Ensure the knee of the working leg tracks directly over the toes, avoiding any internal collapse.
• Keep the non-working leg fully locked out to maximize the active stretch on the adductors.

Pro tips

• Actively 'pull' your hips down into the working side's hip socket to maximize glute engagement and depth.
• Maintain high tension in your upper back and lats to prevent the barbell from shifting as you move laterally.

Make it harder

• Perform 'low transitions' by staying at the bottom of the squat and sliding across to the other side without standing up between reps.
• Increase the eccentric phase to 4 seconds to further challenge hip stability and mobility.
