Kettlebell Windmill
What Is the Kettlebell Windmill?
Kettlebell Windmill is a compound exercise that primarily targets the core, especially the obliques, and also engages the glutes, hamstrings and the shoulder that holds the bell overhead. It is an intermediate-level movement that combines a hip hinge, a controlled lean of the torso to one side and a one-arm overhead lockout that stays in place for the whole rep.
The windmill trains three things at once: trunk control while the body folds under a load, hip mobility on the side that holds the bell, and shoulder stability with the arm straight overhead. That mix makes it a staple of kettlebell programs, where it is often taught after the Kettlebell Turkish Get-Up and used as a stepping stone toward the bent press. It is usually done for low reps, around 3 to 5 per side, in a warm-up or as accessory work after the main lifts, rather than as something to push to fatigue.
Most of the work comes from the hip on the bell side. That hip sits back and takes most of your weight while the straight leg's hamstrings lengthen, and the glutes drive you back up. The obliques control how far the torso leans and bring it back to upright, and the shoulder muscles and rotator cuff keep the bell stacked over the joint. In a low windmill the bell sits in the bottom hand instead, which turns it into a loaded side hinge with far less shoulder demand, and a double windmill holds one bell overhead and a second in the bottom hand. The version on this page keeps a single bell overhead.
The windmill suits lifters who already hinge well and can press and hold a kettlebell overhead with a straight elbow. Before loading it, learn the pattern with the arm raised and no weight, then try a low windmill, and build the lockout with the Kettlebell Single-Arm Military Press and the get-up. Feeling the bell-side hip sit back, rather than the waist bending, is the one sensation worth chasing.

Instructions
- Clean and press a kettlebell overhead with one hand, then stand with your feet wider than shoulder width and your toes turned slightly out.
- Lock the elbow so the arm is vertical over the shoulder, with the bell resting on the back of your forearm and the wrist straight. Let the free arm hang by your side.
- Turn your head to look up at the kettlebell, and keep your eyes on it for the whole rep.
- Push the hip on the bell side back and out to the side so most of your weight sits on the bell-side leg. Keep that leg straight.
- Hinge at the hips and lower your torso toward the free side, sliding the free hand down the inside of the leg on the free side toward the foot. Let that knee bend softly as you go.
- Keep the overhead arm vertical and your spine long as you lower, letting your chest turn slightly toward the ceiling rather than collapsing sideways.
- Stop when you can go no lower without the arm drifting, the bell-side knee bending or the back rounding.
- Drive the bell-side hip forward and squeeze your glutes to return to standing, keeping the arm locked and your eyes on the bell.
- Finish all reps on one side, lower the bell under control and switch hands.
Common Mistakes
Side bending instead of hinging
Curling the torso sideways at the waist instead of pushing the bell-side hip back loads the lower spine and takes the hips out of the movement.
Arm drifting off vertical
Letting the bell drift forward or behind the shoulder forces the joint to hold the load at an angle it cannot support well.
Bending the bell-side knee
Softening the straight leg turns the rep into a squat and removes the hip hinge the windmill depends on.
Looking away from the bell
Looking at the floor lets the overhead arm wander without you noticing until the bell is already out of line.
Forcing depth
Reaching for the floor before the hips allow it rounds the back and pulls the shoulder out of position.
Using a bell that is too heavy
A bell you cannot press and hold steadily overhead makes the lockout the weak link of every rep.
Injuries
Kettlebell Windmill is a medium risk exercise when performed with proper technique. The load is usually light, but the lower back and the overhead shoulder both work close to the end of their range, so small form errors add up quickly.
The lower back is the most common strain point. When the rep turns into a side bend, with the spine curling sideways and twisting instead of the hip sitting back, the lumbar spine takes load it handles poorly. The overhead shoulder is the second: if the bell drifts forward or behind the joint, the shoulder has to hold it at an awkward angle. Forcing depth can also overstretch the hamstrings of the straight leg.
Warm up the hips and shoulders first, and go only as low as you can keep the arm vertical, the bell-side leg straight and the spine long. Use a bell you can press strictly overhead for several reps, and keep sets short so the lockout never gets shaky. To regress, drop the bell and do the movement with the arm raised, try a low windmill with the bell in the bottom hand, or build side-trunk strength with the Side Plank. Progress with a slightly heavier bell or a short pause at the bottom.
Stop the set if you feel sharp pain in the lower back, a pinch in the front or top of the shoulder, or the bell starts to wobble. Anyone with shoulder impingement or instability, a recent disc or sacroiliac joint problem, or recent spine, shoulder or abdominal surgery should get clearance before doing loaded windmills.

Frequently Asked Questions
- Q: What is the difference between a high and a low windmill?
In the high windmill the bell stays locked out overhead, so the shoulder has to stabilize it through the whole rep. In a low windmill the bell sits in the bottom hand and you pick it up from the floor, which is easier on the shoulder and a common first step before loading the top arm.
- Q: Which way should my feet point?
Many coaches turn both feet about 45 degrees away from the bell side, which makes it easier to sit into the bell-side hip. A wide stance with the toes turned slightly out also works, so use whichever lets you hinge deepest without the heel of the bell-side foot lifting.
- Q: Is the windmill just a weighted side bend?
No. A Dumbbell Side Bend bends the spine sideways against a weight in the hand, while the windmill moves mostly at the hip with the spine kept long and the chest turning slightly toward the ceiling. The obliques work hard in both, but in the windmill they control the lean rather than create it.
- Q: How heavy should I go and how many reps?
Keep the bell light and the reps low, around 3 to 5 per side, using a weight you can press strictly overhead for several reps. It is a skill and stability drill, so stop the set while every rep still looks the same.
- Q: Should I learn the Turkish get-up before the windmill?
It helps. The Kettlebell Turkish Get-Up builds the same straight-arm lockout with the floor supporting you for much of the rep, and the windmill then adds a deeper hip hinge and a longer lean under the bell.
- Q: Do I need to touch the floor?
No. Go only as low as you can keep the overhead arm vertical, the bell-side leg straight and the spine long, and let depth improve over the weeks as your hips loosen up.
