Kettlebell Windmill
The kettlebell windmill is a slow, controlled movement in which you hold a kettlebell locked out overhead on one arm and hinge and side-bend beneath it, reaching your free hand down the inside of your leg. It trains the obliques, the deep muscles at the side of the low back and the glutes, together with overhead shoulder stability and hip mobility.
Also called: KB Windmill, Kettlebell Windmills, Overhead Windmill, Kettlebell Side Windmill · Equipment: kettlebell · Pattern: compound
Step by step
- Clean and press a light kettlebell overhead with one arm and lock it out, with your biceps by your ear and your wrist straight.
- Stand with your feet about shoulder-width apart and turn both feet about 45° away from the bell side.
- Look up at the bell and keep your eyes on it for the whole rep.
- Push the hip on the bell side back and out to the side. As you hinge, slide your free hand down the inside of the leg on the free-hand side, keeping the leg under the bell straight and the other knee soft.
- Let your trunk turn and side-bend as you go down, keeping your spine long and the overhead arm vertical.
- Go only as deep as your hips and upper back allow with a long spine; for many lifters that is around mid-shin. Pause briefly at the bottom.
- Drive through your feet and bring your hips back underneath you to stand tall, with the overhead arm still locked out.
- Complete all reps on one side, bring the bell down to your shoulder and then to the floor, and change sides.
- Eyes on the bell throughout
- Push the hip back and out to the side
- Overhead arm stays vertical, like a post
- Long spine all the way down
- Slide the free hand down the inside of your leg
- Control the bottom, no bounce

What goes wrong, and the fix
Side-bending at the waist instead of hinging
Fix: Push the hip on the bell side back and out, and let the hips lead the descent.
Chasing the floor
Fix: Go only as deep as your hips and upper back allow with a long spine.
Eyes leaving the bell
Fix: Keep your eyes on the bell and the overhead arm vertical for the whole rep.
Overhead elbow bending
Fix: Lock the elbow fully and keep your biceps by your ear throughout the set.
Bell too heavy for the position
Fix: Choose a bell you can hold locked out overhead for the whole set with ease.
What the research says
Rehab & prehabGeneral fitnessSport performance
- Evidence base — There is no training research on the windmill itself. A scoping review of kettlebell studies found mostly trivial-to-small effects and rated confidence in the reported outcomes as low to very low.
- Sets and reps — A common approach is 2–3 sets of 3–6 reps per side with a light bell, in a warm-up, mobility block or accessory slot. There is no direct research comparing windmill set and rep schemes.
- Range of motion — Reviews find full-range training produces greater strength gains than partial range and tends to favour muscle growth, most clearly in the legs. The windmill loads the obliques at long length, but the usable load is small.
- Placement — Research on exercise order finds the lift trained earlier in a session tends to show the larger strength gain. Many lifters place the windmill early, or in the warm-up, while the shoulder is fresh for the overhead hold.
- Pairings — It is commonly paired with anti-rotation work such as the Pallof press and with loaded carries.
