Kettlebell Windmill
The kettlebell windmill holds a kettlebell locked overhead in one hand while you hinge at the hips and reach your free hand down toward the floor, keeping your eyes on the kettlebell the whole time. It trains your core to resist bending sideways under an offset overhead load while your hips move through a hinge, rather than working the abs through a straight crunching motion. It suits lifters who already hinge comfortably and want a rotational core and shoulder-stability challenge.
Why it works
Holding a kettlebell overhead on one side pulls your ribcage toward that shoulder unless your obliques and deep core muscles actively resist it. Hinging at the hips while reaching your free hand toward the floor adds a second demand on top of that: your hamstrings and glutes control the hinge while your core keeps you from folding sideways toward the low hand instead of hinging straight back. Your shoulder, meanwhile, has to hold the kettlebell locked in place through the whole range, which is what makes the windmill train anti-lateral-flexion core strength and overhead shoulder stability in the same rep.
Set up
- Clean or press a kettlebell overhead in one hand, locking your arm out with your palm facing forward.
- Turn your feet out slightly, angled away from the kettlebell side.
- Fix your eyes on the kettlebell before you start hinging.
How to do it
- Push your hips back on the side opposite the kettlebell, starting the hinge.
- Keep your overhead arm locked and reach your free hand down your leg toward the floor.
- Lower until you feel a stretch through your hamstrings or reach as far as you can while keeping the kettlebell locked overhead.
- Pause briefly at the bottom of the reach.
- Reverse the hinge, driving your hips forward to return to standing with the kettlebell still stacked overhead.
Form cues
- Track the kettlebell with your eyes through the entire rep.
- Hinge your hips back rather than bending forward at the waist.
- Keep the overhead arm locked out and vertical, don't let it drift forward or behind you.
- Move slowly through the reach, don't drop quickly toward the floor.
Breathing: Inhale as you hinge down and reach toward the floor, exhale as you drive your hips forward to return to standing.
Common mistakes
Letting the kettlebell drift forward or out of line with your shoulder.
Fix: Keep your locked arm pointing straight up throughout the movement, checking that your wrist stays over your shoulder.
Bending forward at the waist instead of hinging at the hips.
Fix: Push your hips back first, letting your torso lower as a result of the hinge rather than folding forward on its own.
Rushing the reach down and back up.
Fix: Slow the tempo down so your core has time to control the sideways pull of the overhead load.
Using a kettlebell too heavy to keep locked out comfortably overhead.
Fix: Drop the weight until you can hold a full lockout through the entire hinge without your arm shaking.
How to program it
- Two or three sets of five to eight reps per side are enough, since the range of motion and control matter more than volume here.
- This works well early in a session, paired with other hip hinge or overhead work, while you're still fresh enough to control the rotation.
- One or two sessions a week that include the windmill are plenty for most lifters, since it's a stability and mobility movement rather than a heavy strength builder.
Safety notes
- Only reach as low as you can while keeping your overhead arm locked and your lower back from rounding.
- Stop the rep if the kettlebell wobbles or your shoulder loses lockout; that's a sign the weight or range is too much for now.

Frequently asked questions
What muscles does the kettlebell windmill work?
It primarily works your abdominals, plus your glutes, hamstrings, shoulders, and triceps, through the combined hip hinge and overhead hold.
How heavy should the kettlebell be for a windmill?
Light to start. Since the arm has to stay locked overhead through a hip hinge, most people use a lighter kettlebell than they would for a straight overhead press.
Can I do a kettlebell windmill without any equipment?
Yes. The bodyweight version, sometimes called simply windmills, trains the same hip hinge and torso rotation pattern without holding anything overhead.
How low should I reach in a kettlebell windmill?
Only as low as you can go while keeping your overhead arm locked and your lower back flat. Reaching further than your hip mobility allows usually means your lower back rounds to compensate.
