Kettlebell Single-Arm Overhead Squat
What Is the Kettlebell Single-Arm Overhead Squat?
Kettlebell Single-Arm Overhead Squat is a compound exercise that primarily targets the quadriceps and also engages the glutes, inner thighs, shoulder, upper back and trunk. It is an advanced-level movement: you hold one kettlebell locked out overhead on a straight arm and squat to full depth, which asks for mobility at the ankles, hips, upper back and working shoulder as well as leg strength and steady control of the bell.
The single, offset load is what sets it apart from the Barbell Overhead Squat and the Dumbbell Overhead Squat. With a barbell both arms share one bar, and with two dumbbells each arm balances its own weight, but the load stays centered over the body. Here all of the weight sits over one shoulder, so it pulls you toward the bell side and tries to turn your torso. The trunk, especially on the free side, has to resist that lean and twist to keep you upright and square, and the working shoulder holds the lockout with no help from the other arm. The bell is far lighter than an overhead squat barbell, so control, not load, is usually the limit.
Coaches often use it with a light bell as a check of overhead and squat mobility, because a stiff ankle, hip, upper back or shoulder shows up quickly as the bell drifting forward or the torso folding. It also builds the overhead stability used in kettlebell lifts that hold a bell over one shoulder, such as the Kettlebell Snatch, Kettlebell Windmill and Kettlebell Turkish Get-Up. Training each arm separately also shows whether one side is stiffer or less stable than the other.
It suits lifters who can already squat to full depth with their heels down and press a kettlebell overhead with one arm. Build up with the Kettlebell Goblet Squat for depth, and the Kettlebell Single-Arm Military Press and Kettlebell Overhead Carry for a steady lockout. Train both arms, and let the weaker side decide the bell you use.

Instructions
- Stand with your feet about shoulder-width apart and your toes turned slightly out, with the kettlebell on the floor between your feet.
- Clean the kettlebell to your shoulder with one hand, then press it straight up until your elbow locks.
- Set the lockout: arm straight and vertical, the bell resting on the back of your forearm, wrist straight and the bell stacked over your shoulder and the middle of your feet.
- Push your shoulder up into the bell, let your free arm hang by your side with a firm fist, look straight ahead and brace your trunk.
- Squat by bending your hips and knees together, keeping your torso tall and your shoulders and hips square to the front.
- Lower until your hips are below your knees, or as deep as you can keep your heels down, your elbow locked and the bell over the middle of your feet.
- Drive through both whole feet, keeping the free-side foot pressed firmly into the floor, and stand up with your hips and chest rising together.
- Repeat for the planned reps, bring the bell back down to your shoulder under control, then set it down and do the same number of reps on the other arm.
Common Mistakes
Bending the elbow
A soft elbow lets the bell sink toward the head and turns a stable lockout into a shaky partial press, so keep the arm straight and the elbow locked on every rep.
Bell drifting forward
When the arm tips in front of the head the shoulder has to hold the bell out of line, so keep it stacked over the shoulder and the middle of the foot and stop the squat where that position is lost.
Leaning toward the bell
Letting the offset load pull the torso to the bell side lets the opposite knee and hip collapse, so keep the torso upright and press the free-side foot firmly into the floor.
Twisting and dropping the free shoulder
Turning the torso or dropping the free shoulder to make room for the bell collapses the opposite side, so keep the shoulders and hips square to the front and reach the working arm up instead.
Wrist bent back
Letting the bell pull the wrist back strains the forearm and weakens the lockout, so keep the wrist straight with the bell resting on the back of the forearm.
Injuries
Kettlebell Single-Arm Overhead Squat is a medium risk exercise when performed with proper technique. The bell is usually light, but it is held over one shoulder at the deepest point of a squat, where a lost lockout or a shift to one side happens quickly.
The main strain points are the working shoulder, the wrist, the lower back and the knees. Forcing the arm back past what the shoulder and upper back allow, or letting the shoulder sink under the bell, stresses the shoulder joint. A wrist bent back under the bell strains the wrist and forearm. When the upper back cannot extend enough, people often arch the lower back and flare the ribs to get the arm vertical, and leaning toward the bell side lets the opposite knee and hip collapse inward. Keep the elbow locked, the wrist straight, the shoulder pushed up into the bell, the ribs down and the torso square, and press evenly through both feet.
To make it easier, use a lighter bell, practice the lockout with the Kettlebell Overhead Carry, squat to a box or bench set at a depth you can control, or raise your heels on a small plate. An overhead lunge such as the Dumbbell Overhead Lunge builds the same lockout with less hip and ankle range. To progress, use a heavier bell or add a pause at the bottom, and press from the bottom position with the Kettlebell Sots Press once the hold is solid.
End the set when the elbow bends, the bell drifts in front of the head or the torso starts to lean or twist toward the bell. If the bell gets away from you, do not fight it overhead: guide it back down or move out from under it. Stop completely if you feel sharp or pinching pain in the shoulder, wrist, back or knee.

Frequently Asked Questions
- Q: How is it different from the barbell or dumbbell overhead squat?
Only one arm holds the load, so the weight sits off to one side and tries to pull you into a lean and a twist that your trunk has to resist. You use far less weight than with a Barbell Overhead Squat, and each side is trained on its own.
- Q: How should I hold the kettlebell overhead?
Hold the handle deep in your palm with the bell resting on the back of your forearm, the wrist straight and the elbow locked. Holding it bottoms-up, with the bell balanced above the hand, makes the grip and wrist the limit and is a separate, harder variation.
- Q: What should my free arm do?
Let it hang by your side with a firm fist, which helps keep that side of the trunk tight. Reaching the free hand toward the floor turns the torso toward the bell and makes it a different movement, closer to a Kettlebell Windmill.
- Q: Where should I look during the squat?
Look straight ahead with your head level. Some coaches teach watching the bell, but if looking up makes you arch your back or lose your balance, keep your eyes forward.
- Q: How heavy should the kettlebell be?
Use a bell you can press overhead with one arm comfortably and keep locked out at the bottom of the squat. The working weight is set by your weaker side, so use the same bell for both arms.
- Q: Why can't I squat as deep with the bell overhead?
If you can sit deep in a Kettlebell Goblet Squat but not here, the overhead position is the limit, usually the shoulder or upper back rather than the legs. Squat only as deep as you can keep the arm vertical and the torso square, and work on overhead mobility alongside.
