Setup
- Stand with feet slightly wider than shoulder-width apart, toes pointed slightly outward.
- Clean and press the kettlebell overhead with one arm, locking the elbow completely.
- Rotate your palm forward or slightly inward and pull your shoulder blade down and back into a stable position.
- Extend the non-working arm out to the side for balance and brace your core deeply.
How to do it
- Inhale and begin the descent by pushing your hips back and down while keeping the kettlebell stacked directly over your shoulder.
- Lower until your thighs are at least parallel to the floor, maintaining a vertical torso and a locked-out arm.
- Exhale and drive through your heels to return to the standing position, keeping the kettlebell stable and overhead.
- Complete all repetitions on one side before switching the kettlebell to the opposite arm.
Form checklist
- Keep the elbow fully locked and the bicep close to the ear throughout the movement.
- Maintain a neutral spine and avoid letting the kettlebell pull your torso into a side-bend.
- Ensure your knees track in line with your toes and do not cave inward during the squat.
- Keep your gaze forward or slightly up at the kettlebell to assist with balance.
- Keep the weight centered over the mid-foot, ensuring heels stay glued to the floor.
Pro tips
- Actively 'punch' the kettlebell toward the ceiling to engage the serratus anterior and stabilize the shoulder joint.
- Focus on 'spreading the floor' with your feet to maximize glute engagement and create a more stable base.
Make it harder
- Add a 3-second pause at the bottom of the squat to increase time under tension and stability demands.
- Slow down the eccentric phase to a 4-second count to further challenge the core and shoulder stabilizers.
