Kettlebell Arm Bar
The kettlebell arm bar is a lying drill where you hold a kettlebell overhead on a straight arm and roll onto your side underneath it, keeping the arm vertical. It trains shoulder control and stability with the arm overhead and opens the chest and upper back.
Also called: KB Arm Bar · Equipment: kettlebell · Pattern: isolation
Step by step
- Lie on your back with the kettlebell beside your right shoulder, then take the handle in both hands and press it up to a straight right arm, fist to the ceiling.
- Bend your right knee with the foot flat, and reach your left arm along the floor above your head with your left leg straight.
- Keep your eyes on the bell and set your right shoulder down away from your ear.
- Push through your right foot to roll onto your left side, letting the right leg cross over to the floor while the right arm stays vertical.
- Settle your hips and let your chest open towards the ceiling, keeping the wrist straight and the arm locked.
- Hold for your chosen time, breathing steadily.
- Roll back onto your back with the arm still vertical, bring the bell down to your chest with both hands, and switch sides.
- Eyes on the bell the whole time
- Arm vertical, fist to the ceiling
- Shoulder down, away from your ear
- Wrist straight under the bell
- Roll the body, not the arm
- Let the chest open as you settle

Shoulder shrugging to the ear

What the research says
Rehab & prehabGeneral fitness
- Use — The arm bar is commonly used in a warm-up or as preparation for get-ups, windmills and overhead pressing, with a light bell.
- Dose — A common approach is 2–3 holds of 20–60 seconds on each side. There is no research on the dose.
- Research — A scoping review of kettlebell research found mostly small, low-quality studies with small effects, and no study of the arm bar was found.
- Progression — A common path is a longer hold, then a slightly heavier bell, then related drills such as the windmill.
