Cossack Squats — GOAT Leg Strength & Mobility (Weighted)

💡 How to follow: Tom Morrison's weighted cossack squat breakdown: goblet hold, wide stance (feet outside shoulders, toes out ~5-to-1 on a clock), neutral spine, hips back and down to one side, heels down, extended leg straight; once hips pass parallel, return. Weight in front = more core activation, more leg strength, and a deeper loaded position for mobility. Then 5 variations ('wiggles') and 3 regressions for ankles, rounding back, and tight quads.

The Base Cossack Squat

6–12 reps per side
The Base Cossack Squat

Weight in front in a goblet position, wide stance (feet outside shoulder width, toes out slightly — 5-to-1 on a clock). Neutral spine, squat over to one side sending hips back and down, heels on the floor, extended leg straight. Below parallel, return — alternate sides or do one side at a time.

  1. Goblet hold in front
  2. Wide stance, toes out ~5-to-1
  3. Neutral spine, hips back and down
  4. Heels stay down; straight extended leg
  5. Hips past parallel → return

Why Weight in Front

Understand
Why Weight in Front

Holding the load in front increases core activation, builds more leg strength through the movement with the extra load, and lets you load a deeper position to improve mobility.

  1. More core activation
  2. More leg strength via extra load
  3. Loads a deeper position
  4. Grows mobility under load

5 Wiggles — Explore the Position

Pick 1–3 per session
5 Wiggles — Explore the Position

1) Foot of the extended leg: flat = adductor strength; toe up = more groin stretch + hamstring/back-of-leg work. 2) Add twists, leans, reaches — bottom-position control. 3) Move the weight away from your body — changes center of mass. 4) Slide side-to-side staying low, pulling with the feet, instead of returning to center each rep.

  1. Flat foot → adductor strength
  2. Toe up → groin stretch + hamstring
  3. Twists, leans, reaches for control
  4. Move the weight around
  5. Slide low side-to-side, pull with feet

Regressions — Meet Yourself Where You Are

As needed
Regressions — Meet Yourself Where You Are

Ankles holding you back? Elevate the heels to keep a more upright torso. Back rounding? Push the weight fully away for counterbalance. Quads bothering you? Squat to a box behind the bent leg, just below your controllable point — use that for your range.

  1. Heels elevated → upright torso
  2. Weight away → counterbalance
  3. Box behind bent leg → controlled range
  4. Build range pain-free, in control
