Setup
- Clean two kettlebells to the rack position, holding them at chest height with elbows tucked and handles resting across the base of your palms.
- Set your feet shoulder-width apart with toes slightly pointed out.
- Engage your core and pull your shoulder blades down and back to create a stable shelf for the weights.
How to do it
- Inhale as you sit your hips back and down into a deep squat, keeping your chest upright and weight distributed through your mid-foot and heels.
- Exhale and drive explosively through your legs to return to a standing position.
- As you reach the top of the squat, use the upward momentum to press one kettlebell vertically overhead until your arm is fully locked out.
- Lower the kettlebell back to the rack position with control, then immediately begin the next squat, alternating the pressing arm on the next ascent.
Form checklist
- Keep your elbows tucked close to your ribs in the rack position to protect the shoulders.
- Maintain a vertical torso throughout the squat to prevent the kettlebells from pulling you forward.
- Ensure your hips reach full extension before the arm begins the overhead press.
- Avoid leaning to the side of the non-pressing arm; keep your spine neutral and core braced.
Pro tips
- Focus on the 'transfer of energy' from your legs to your shoulder; the press should feel like a fluid continuation of the squat's upward drive.
- Squeeze the handle of the non-pressing kettlebell tightly to create 'irradiation,' which increases total body tension and stability.
Make it harder
- Add a 2-second pause at the bottom of the squat to remove momentum and increase time under tension.
- Perform a '1.5 rep' style where you do a full squat, a half squat, and then the thruster press.
