One kettlebell locked out overhead while you push your hips sideways and fold down to touch the floor with your free hand, eyes on the bell the whole way. It trains overhead shoulder stability, lateral trunk control and hip mobility in a single position most lifters have never asked their body to hold.

How to

Own the movement

Set up first, then execute. Every cue below is something you can check on your next set.

Before the first rep

  • Clean and press one bell overhead, then lock the elbow hard and pack the shoulder down into the socket.
  • Turn both feet out roughly 45 degrees away from the loaded arm.
  • Load the same-side hip: weight shifts onto the leg under the bell, front leg stays straight.
  • Start unloaded — run the whole pattern with an empty hand overhead before you ever hold a bell.
  • Fix your eyes on the bell before the first rep and keep them there.

Every rep

01
Push the loaded hip out sideways to start the descent — the hips move before the torso does.
02
Keep the front leg straight and let the rear knee bend only slightly.
03
Track your free hand down the inside of your front leg toward the floor.
04
Keep the overhead arm vertical and the elbow locked for every centimetre of travel.
05
Pause a beat at the bottom, then reverse by driving the loaded hip back under you.
06
Stop the descent where your form stops, not where your hand stops — the floor is not compulsory.

Breathing & tempo — Inhale as you descend, hold a light brace at the bottom, exhale as you drive back up. Three seconds down, a one-second pause, two seconds up. Never rush the descent.

Before you load it

  • If your shoulder does not comfortably lock out overhead with the elbow straight, fix that before loading it here — the windmill holds the overhead position far longer than any press does.
  • Practise bailing with a light bell: if the shoulder gives, step away and let it fall rather than trying to steer it down.
Programming

Sets, reps & load

Where to start, and what to change when it stops being hard.

Strength
4-5 sets of 3-5 per side
Hypertrophy
3-4 sets of 5-8 per side

Learn it empty-handed, then hold a light object, then take 8-12 kg. Good looks like a full descent with a straight front leg, a locked elbow and no wobble at the bottom. Add weight only when you own that at the current bell — moving from 12 kg to 16 kg is a genuine jump here, far bigger than the same jump feels in a swing.

Fix your form

What goes wrong

The errors that show up most often, and the cue that fixes each one.

Bending sideways at the waist instead of pushing the hip out.

Stand next to a wall with the loaded hip a hand's width from it, and start each rep by pressing that hip into the wall. The fold should feel like a hinge across, not a crumple down.

Taking the eyes off the bell to look at the floor.

Keep your gaze locked on the bell for the whole rep. Looking away loses the shoulder position and is usually the last thing that happens before a bell comes down.

Chasing the floor with a bent front knee and a rounded back.

Go only as deep as you can with a straight front leg and a long spine, even if that is halfway down your shin. Depth comes from hamstring and adductor length, which takes weeks, not reps.

Starting heavy because your press is strong.

Your overhead press number is irrelevant here. Run the pattern with no weight, then a shoe, then 8-12 kg. The limiting factor is control at the bottom, not strength at the top.

The case for it

Why bother

The overhead arm never moves relative to the floor — you rotate your body underneath it. That means the shoulder has to hold a locked-out, externally rotated position while the trunk changes angle by 60 or 70 degrees beneath it. Very little else in a normal programme asks the shoulder to stabilise through that much torso movement.

The descent is a lateral hinge, not a side bend. The hip on the loaded side pushes out and back while the front leg stays straight, so the hamstring and adductor of that leg are stretched under control and the obliques resist the side that wants to collapse. If it feels like a stretch first and a strength exercise second at light weight, that is honest — it becomes a strength exercise as the bell gets heavier.

Where it fits

Early in an upper-body or full-body session, after the warm-up and before pressing, when your shoulder is fresh and your attention is intact. Sets of 3-6 per side, twice a week. Do not use it as a burnout finisher — a fatigued shoulder under a bell in this position is the failure mode worth avoiding.

Swap it out

If this one isn't it

No kit, too hard, or too easy — here's where to go instead.

Questions

Asked and answered

Do I have to touch the floor?

No, and treating the floor as the target is how people round their backs into it. Descend as far as you can with a straight front leg, a long spine and a vertical overhead arm. For many people that is mid-shin at first. Depth improves over weeks as the hamstrings and adductors on the front leg lengthen.

How is this different from a bent press?

In a windmill the bell is already locked out overhead and stays there — you are lowering and raising your body under a fixed arm. In a bent press you start with the bell racked at the shoulder and press it by moving your body away from it, so it is a pressing exercise. Windmill first; the bent press is the harder skill.

What weight should I start with?

None. Run the pattern with an empty overhead arm for a session or two, then take 8 kg if you are new to kettlebells and 12 kg if you are not. The bottom position is the test, and it exposes hip and hamstring restriction long before it exposes a lack of strength.

Is the windmill safe for my lower back?

Done as a lateral hinge with a long spine, yes — the load is light and the spine stays neutral. Done as a side bend with a rounded back and a rotating ribcage, it stacks compression and rotation on a flexed lumbar spine, which is the one combination worth avoiding. The difference is entirely whether the hip moves first.
