Setup
- Stand with feet shoulder-width apart and clean the kettlebell into the 'rack position' with the bell resting on the outside of the forearm, tucked close to the chest.
- Keep your wrist straight and your elbow tucked slightly in front of your shoulder, not flared out to the side.
- Engage your glutes and core to create a stable base and prevent your lower back from arching.
How to do it
- Exhale as you press the kettlebell vertically, rotating your palm from facing inward to facing forward at the top of the movement.
- Drive the weight until your arm is fully locked out overhead with your bicep aligned with your ear.
- Inhale as you control the descent, 'pulling' the kettlebell back down into the rack position with a controlled 2-second tempo.
Form checklist
- Keep your forearm vertical throughout the entire pressing motion.
- Avoid leaning to the opposite side; keep your torso upright using your obliques to resist the offset load.
- Ensure the wrist remains neutral and does not bend backward under the weight of the bell.
- Maintain a 'packed' shoulder by keeping your shoulder blade down and away from your ear.
Pro tips
- Squeeze the handle as hard as possible to increase neural drive and shoulder stability through irradiation.
- Create full-body tension by making a fist with your non-working hand to help stabilize the spine during the press.
Make it harder
- Perform the press from a half-kneeling position to further challenge core stability and eliminate leg drive.
- Transition to a 'Bottoms-Up' press, holding the kettlebell upside down to maximize grip strength and rotator cuff activation.
