Setup
- Stand with feet shoulder-width apart and clean a kettlebell to a 'bottoms-up' position at shoulder height.
- Grip the handle firmly so the heavy base of the bell is pointing directly toward the ceiling.
- Position your elbow slightly in front of your ribs with your forearm perfectly vertical and your wrist straight.
- Engage your glutes and core to create a rigid, stable base for the press.
How to do it
- Exhale and press the kettlebell vertically, keeping your eyes on the bell to monitor its balance.
- Maintain a slow, controlled tempo to prevent the kettlebell from tipping or swaying.
- Reach full elbow extension at the top without shrugging your shoulder into your ear.
- Inhale as you slowly lower the kettlebell back to the starting position, keeping the forearm vertical throughout the descent.
Form checklist
- Keep a 'white-knuckle' grip on the handle to maximize forearm and shoulder stability.
- Ensure the wrist does not bend or cock back; it must remain neutral and stacked.
- Keep your ribs tucked and avoid arching your lower back as the weight moves overhead.
- Maintain a vertical forearm path; if the elbow flares too wide, the bell will tip.
Pro tips
- Utilize 'irradiation' by squeezing your non-working hand into a fist to increase full-body tension and stability.
- Focus on pulling your shoulder blade down and back into your 'back pocket' as you press to engage the serratus anterior.
Make it harder
- Perform the press from a half-kneeling position to remove leg drive and further challenge pelvic stability.
- Add a 3-second isometric hold at the top of each rep to maximize stabilizer recruitment.
