What is Goblet Cossack Squat?

The Goblet Cossack Squat is a kettlebell-held lateral single-leg squat that builds hip mobility and unilateral leg strength. It primarily targets the quadriceps, hamstrings, glutes and supporting back muscles. This medium-level calisthenics move demands ankle and hip mobility plus core control for safe depth and balance.

How to Do Goblet Cossack Squat

  1. Setup stance: Hold a kettlebell close to your chest, stand with feet wide, toes slightly turned out, hips squared and back neutral.
  2. Shift weight: Shift your weight to one leg, hinge at the hips and bend the working knee while keeping the opposite leg straight and toes flexed.
  3. Descend controlled: Lower into a deep lateral squat, keep the heel of the bent leg down, spine neutral and chest tall; avoid rounding the back.
  4. Pause and brace: Pause at the bottom, brace your core and actively pull yourself into the position to maintain stability and prevent collapsing.
  5. Drive upward: Drive through the heel of the bent leg, extend knee and hip, squeezing the glutes to return to standing with controlled motion.
  6. Switch sides: Fully extend hips, reset feet and repeat on the other side for equal reps; start with lighter weight to master form.

Description

Take a kettlebell and hold it against your chest, elbows in close & pointed down.
Take a wide stand with your feet. Hips and shoulder square, back neutral. Feet should be turned out slightly, this will vary person to person.

Squat to one side, by flexing one knee and hinging at the hip.
Keep the heel down, & drive the knee forward, tracking in line with the foot. Pull yourself actively into the bottom position, keeping your spine netural, & stacking the hip on top of the heel.

Descend as low as you feel comfortable, stay tight, & ensure the other leg stays straight. Pause at the bottom. Don't go into posterior pelvic tilt.

Drive through the heel, extending the knee and hip to return to the start.

Frequently Asked Questions

What are the benefits of the Goblet Cossack Squat?

Improves single-leg strength, hip mobility, and balance while developing quads, hamstrings, glutes and core stability. The goblet position promotes upright posture and loading tolerance, aiding carryover to squats, lunges and athletic movements.

What common mistakes should I avoid?

Avoid letting the bent knee collapse inward, rounding the lower back, lifting the heel, and forcing depth beyond mobility. Don’t hold the kettlebell too low or let the non-working leg bend—these reduce stability and increase injury risk.

How can I progress or regress this exercise?

To regress, use no weight, reduce depth, or perform supported side squats holding a stable object. Progress by increasing kettlebell load, adding slow eccentric tempo, deeper pauses, or advancing toward pistol/single-leg squat variations when ready.
