The One-Arm Kettlebell Press is a unilateral strength exercise where you press a kettlebell overhead from a racked position at shoulder height, using one arm at a time while stabilizing your core. Its primary purpose is to build shoulder power, pressing strength, and anti-rotational stability. It mainly targets the deltoids, with secondary engagement of the triceps, upper chest, and core muscles, benefiting athletes, functional fitness enthusiasts, and those addressing strength imbalances with just a single kettlebell.
How to Perform One-Arm Kettlebell Press
- 1Stand tall with feet shoulder-width apart, core braced, and shoulders packed down away from your ears.
- 2Pick up a kettlebell with your right hand using a hook grip (fingers under the handle, thumb locked in), and clean it to the rack position: elbow tucked in, kettlebell resting on your forearm near your chest.
- 3Position your left hand on your hip or by your side for balance, and actively engage your glutes and abs to stay tall.
- 4Inhale deeply, then exhale as you press the kettlebell straight overhead by extending your elbow fully while keeping your wrist straight and shoulder packed.
- 5Pause briefly at the top with your arm locked out, bicep near your ear, and body stable—no leaning or arching.
- 6Inhale as you lower the kettlebell under control back to the rack position, keeping your elbow close to your body.
- 7Perform 6-12 reps per side, then switch to the left arm and repeat.
- 8Key form tips: Maintain a neutral spine—avoid excessive back arching or side-bending. Keep the working shoulder depressed and retracted throughout. Common mistakes: Flaring the elbow wide, using momentum from the legs, or letting the head jut forward.
