Cossack Lift-Off

A Cossack squat stretches the straight leg's adductors hard at the bottom; the lift-off turns that stretch into usable strength and control. From the deep lateral position you keep both feet in place and float slightly out of the hole, forcing the lengthened inner thigh to produce force. This builds the groin resilience and end-range control that heavy Cossacks and wide stances demand.

How to do it

  1. 1

    Stand with a very wide stance, feet flat, and shift your weight into one deeply bent leg.

  2. 2

    Sink into the Cossack, keeping the opposite leg straight with the heel down and toes up.

  3. 3

    Find a tall chest and settle briefly into the deep bottom position.

  4. 4

    Keeping both feet in place, hover slightly up out of the hole by pulling through the straight leg's inner thigh.

  5. 5

    Hold the end-range contraction for two to three seconds without falling backward.

  6. 6

    Lower under control and repeat, then work the other side.

Tips

  • Keep the straight leg's kneecap facing up so the adductors take the load.
  • Stay tall through the chest; collapsing forward drops you out of the target range.
  • Only work from a depth you can control, since the bottom is where balance is toughest.

Variations

Common mistakes

  • The straight leg's heel peels up off the floor as you sink into the bottom, losing the heel anchor the whole lift-off depends on.
  • Catching your balance by shifting weight forward onto the bent knee instead of firing the straight leg's inner thigh skips the entire point of the drill.
  • The bent knee caves inward past the toes at the bottom of the Cossack, loading the inside of an already deeply flexed joint.
  • Reps pile up on the side that balances more easily, leaving the leg that actually needs the practice with the fewer sets.

Frequently asked

What's a sensible starting dose for the Cossack lift-off, and what should I be able to do first?
Start with two or three lift-offs per side rather than a full set, since holding balance in the bottom of a Cossack is the hard part. You should already own a controlled bodyweight Cossack squat without support before adding the lift-off, since balancing and lifting in an unfamiliar deep position at the same time is a lot to ask of a first attempt.
How do I regress the Cossack lift-off if the full version is too advanced?
Hold onto a sturdy rail or doorframe with one hand while you practice the lift-off, removing the balance demand so you can focus on driving the straight leg's inner thigh. Once you can lift off cleanly with support, try single reps unsupported before building back to full sets.
Who is the Cossack lift-off for, and when should I skip it?
It builds groin strength and control at the deep, wide end range that loaded Cossack squats and lateral athletic movements demand. It's a good fit for lifters and athletes with an established Cossack pattern, but skip it if you have current groin or adductor pain, or if your ankles and hips can't yet reach the position passively, since forcing the range under load is not the fix for a mobility gap.
