Windmill Exercise: Form, Muscles Worked and a 5-Step Progression
Two quite different movements share the name windmill, and most guides only cover one of them. The first is the standing toe-touch you probably did in a school PE lesson: feet wide, arms out, reaching one hand down to the opposite foot. The second is the loaded windmill, usually done with a kettlebell held overhead, where you hinge and rotate underneath a weight you keep locked out above your shoulder.
They look related, and they are, but they train different things and carry different risks. The PE version is a warm-up. The loaded version is a serious exercise for your obliques, hips and shoulder stability, and it deserves to be learned in stages rather than attempted with a heavy bell on day one.
This guide covers both. You will find the form for each, the muscles involved, a five-step progression from no weight to a full overhead windmill, how heavy to go, and the mistakes that turn a good exercise into a sore lower back.
At a glance
- The windmill is a hip hinge with rotation, not a side bend
- It trains the obliques, glutes, hamstrings and the stabilisers around the shoulder
- Learn it with no weight first, then with the weight in the lower hand, then overhead
- Your eyes stay on the raised hand throughout the loaded version
- Low reps work best: 3 to 5 per side with full control
- A dumbbell works perfectly well if you do not own a kettlebell
The two windmills
| Feature | Bodyweight toe-touch windmill | Loaded overhead windmill |
|---|---|---|
| What it is | A dynamic warm-up drill | A strength and stability exercise |
| Arm position | Both arms out to the sides | One arm locked out overhead holding a weight |
| Speed | Rhythmic and fairly quick | Slow and deliberate |
| Main purpose | Warming the hips, hamstrings and upper back | Oblique strength, hip mobility, shoulder stability |
| Typical reps | 10 to 20 per side | 3 to 5 per side |
| Risk level | Low | Moderate, depends heavily on technique |
Both have a place. The first belongs in a warm-up. The second belongs in the main part of a session, treated with the same respect as any other loaded movement.
Muscles the windmill works
The loaded windmill is unusual because it asks for mobility and stability at the same time, in several joints at once.
| Muscle | What it does in the windmill | How hard it works |
|---|---|---|
| Obliques | Control the rotation and stop the torso collapsing sideways | Primary |
| Glutes | Drive the hips back to standing | Primary |
| Hamstrings | Lengthen under load during the hinge, especially on the front leg | Primary |
| Rotator cuff and deltoid | Hold the arm stable overhead as the torso moves beneath it | Substantial |
| Quadratus lumborum and spinal erectors | Keep the spine long rather than rounded | Substantial |
| Lats and lower traps | Pack the shoulder down and keep the arm stacked | Stabilising |
| Adductors | Lengthen on the loaded side as the hips shift | Stabilising |
The key idea is that your shoulder stays still while your body moves around it. Most shoulder exercises move the arm against a fixed torso. The windmill reverses that, which is why it is so good for building stability overhead and so unforgiving if your shoulder mobility is limited.
The obliques work in an interesting way too. They are not crunching you sideways. They are controlling a rotation and resisting a collapse, which is closer to how they function in real life. Our oblique exercises guide covers the other ways to train that quality.
Three things to check first
A loaded windmill asks for three abilities. If one is missing, work on it before adding weight.
| Requirement | Quick check | If you fail it |
|---|---|---|
| A clean hip hinge | Push your hips back with a flat back and a soft knee bend, hands sliding down your thighs | Practise bodyweight hinges and good mornings first |
| Overhead shoulder range | Stand against a wall and raise one arm straight overhead without your ribs flaring or lower back arching | Work on overhead mobility before loading |
| Hamstring length | Reach toward your shin with straight legs and a flat back, getting at least to mid-shin | Do the bodyweight windmill daily for a few weeks |
The hinge is the one that matters most. The windmill is a hinge with a twist added, and if you cannot hinge cleanly you will bend through your spine instead. Our good morning exercise guide teaches the pattern without any equipment.
If you have a current shoulder injury, a history of shoulder dislocation, or ongoing lower back pain, skip the loaded windmill. Holding a weight overhead while rotating underneath it is not the place to test a joint that is already unhappy.
How to do the bodyweight windmill
- Stand with your feet wider than your shoulders and your arms out to the sides at shoulder height
- Keep a soft bend in the knees and brace your midsection lightly
- Hinge forward from the hips and rotate, reaching your right hand toward your left foot
- Let the left arm point up toward the ceiling so your arms form one long line
- Return to standing by driving your hips forward, then repeat to the other side
- Reps: 10 to 15 per side as part of a warm-up
- Keep your back long. Reach by hinging and rotating, not by rounding your spine to get lower
- Go only as far as your hamstrings allow. Touching the foot is not the goal
How to do the loaded windmill
These steps describe a windmill with the weight in your right hand. Use a kettlebell or a dumbbell.
- Set your feet. Stand with feet a little wider than hip width, then turn both feet about 45 degrees to the left, away from the weight
- Get the weight overhead. Press it up with your right arm until the elbow is locked and the weight sits directly above your shoulder
- Look up at the weight and keep your eyes there for the entire rep
- Push your right hip out and back, as if closing a car door with it. Most of your weight shifts onto the right leg
- Hinge and rotate your chest toward the ceiling, letting your left hand slide down the inside of your left leg
- Keep the right arm vertical. The weight stays stacked above the shoulder while your body folds underneath it
- Stop when your hips cannot go back any further with a long spine. For many people that is with the hand at the knee or shin
- Drive the hips forward to stand, squeezing the glutes, with the arm still locked out overhead
Three cues that fix most problems:
- Hip back, not body down. The depth comes from pushing the hip away, not from bending sideways
- Chest open to the ceiling. If your chest faces the floor, you have turned it into a forward bend
- Arm like a post. The overhead arm never bends and never drifts forward
A 5-step progression
Each step has a standard to meet before you move on. Rushing this is how people end up with a tweaked back.
| Step | Exercise | Standard before moving on |
|---|---|---|
| 1 | Bodyweight windmill, arms out | 15 smooth reps per side with a long back |
| 2 | Bodyweight overhead windmill, one arm raised | 10 slow reps per side, eyes on the hand |
| 3 | Low windmill, weight in the bottom hand | 3 sets of 5 per side |
| 4 | High windmill, light weight overhead | 3 sets of 5 per side with a vertical arm |
| 5 | High windmill, working weight | 3 sets of 3 to 5 per side |
Step 2 is worth more time than people give it. Practising with an empty raised hand teaches you to keep the arm vertical and your eyes up without any consequence for getting it wrong. A shoe balanced on your raised fist is a classic drill here: if the shoe falls, your arm moved.
Step 3, the low windmill, puts the weight in the hand that travels toward the floor while the top arm stays empty. It loads the hinge and the obliques without demanding overhead stability, which makes it the ideal bridge.
How heavy should you go?
Lighter than you expect. The limiting factor is shoulder stability and control, not raw strength.
| Your level | Suggested starting weight | Notes |
|---|---|---|
| New to the movement | No weight for 2 to 3 weeks | Earn the pattern first |
| Beginner, steps 3 and 4 | 4 to 8 kg | A light dumbbell is fine |
| Intermediate | 8 to 12 kg | Only once the arm stays vertical every rep |
| Experienced | 12 to 20 kg | Progress slowly, in small jumps |
The test for whether a weight is too heavy: if the overhead arm bends, wobbles or drifts forward, or if you find yourself holding your breath and rushing the rep, drop down. A slow, controlled windmill with 6 kg does far more than a shaky one with 16.
Kettlebell or dumbbell?
| Tool | Advantages | Drawbacks |
|---|---|---|
| Kettlebell | Rests against the back of the forearm, sits comfortably overhead, the traditional choice | You need one, and the wrist position takes practice |
| Dumbbell | Most people already own one, easy to grip, simple to load in small steps | Slightly less stable overhead at heavier weights |
| No weight | Free, safe, ideal for learning and warming up | No loading stimulus beyond the stretch |
A dumbbell works perfectly well. Hold it with a firm grip, keep your wrist straight and stacked over your elbow and shoulder, and follow exactly the same steps.
Sets, reps and where it fits
| Goal | Sets and reps | Rest | Where in the session |
|---|---|---|---|
| Mobility and warm-up | 2 sets of 8 to 10 per side, no weight or very light | 30 sec | Start of the session |
| Stability and control | 3 sets of 5 per side, light to moderate | 60 to 90 sec | After the warm-up, before heavy lifts |
| Strength | 3 to 4 sets of 3 to 5 per side | 2 min | Early, while fresh |
Frequency: twice a week is plenty for the loaded version. The bodyweight version can be done daily as part of a warm-up.
Do not do loaded windmills when tired. This is a skill-heavy movement with a weight above your head. Put it near the start of a session, never at the end as a finisher.
A simple way to use it: pair windmills with a carry and a hinge for a short, complete session.
| Exercise | Sets and reps |
|---|---|
| Bodyweight windmill | 2 x 10 per side |
| Loaded windmill | 3 x 5 per side |
| Romanian deadlift | 3 x 10 |
| Suitcase carry | 3 x 30 seconds per side |
| Side plank | 3 x 30 seconds per side |
A 4-minute warm-up for windmills
The windmill needs your hips, hamstrings and shoulders ready at the same time, so a general warm-up is not quite enough.
- Bodyweight hip hinge: 10 reps, hands sliding down the thighs
- Arm circles: 20 seconds each direction
- World’s greatest stretch: 4 per side, a deep lunge with a rotation toward the front knee
- Wall slides: 10 reps, back against a wall, arms sliding overhead
- Bodyweight windmill: 10 per side
- Overhead hold: 20 seconds per arm with your working weight, standing still
The overhead hold is the step people skip. Standing still with the weight locked out for twenty seconds tells you immediately whether your shoulder is ready to hold it while you move.
How to breathe during a windmill
Breathing is rarely mentioned and it changes how stable the movement feels.
- Breathe in at the top, before you start the descent, and brace your midsection lightly
- Keep a little air and tension as you hinge down, rather than exhaling everything
- Breathe out as you drive the hips forward to stand
- Take a full breath at the top between reps instead of rushing into the next one
Holding your breath for the entire set is a sign the weight is too heavy. You should be able to complete five reps per side while breathing in a steady rhythm.
Eight common mistakes
- Bending sideways instead of hinging. The windmill is not a side bend. If your hips do not move back, you are folding through your spine
- Looking at the floor. Take your eyes off the weight and the arm drifts. Watch it the whole time
- Rounding the back to reach lower. Depth comes from the hips. Stop where your spine stays long
- Letting the overhead arm bend or lean forward, which loads the shoulder badly
- Feet pointing straight ahead. Without the 45-degree turn, your hips have nowhere to go
- Squatting. The front knee stays soft and the back leg stays almost straight. A deep knee bend turns it into a different exercise
- Going too heavy too soon, which is the usual route to a strained back or shoulder
- Rushing. Three seconds down, a brief pause, three seconds up
If you feel it in your lower back or shoulder
Lower back discomfort almost always means you are bending through the spine rather than hinging at the hip. Go back to the bodyweight version, slow it down, and think about pushing your hip toward the wall behind you. If your hamstrings stop you well short of your knee, that is your current range, and forcing past it is what strains the back.
Shoulder discomfort usually comes from an arm that is not truly vertical. Check that you can raise the arm fully overhead without your ribs lifting or your back arching. If you cannot, the loaded windmill is asking for range you do not yet have, and the low windmill is the better choice while you work on it. Our shoulder workout with dumbbells guide includes the overhead strength work that supports this.
Sharp pain, pinching at the front of the shoulder, or pain that travels down the arm or leg is a reason to stop and get it checked rather than to adjust your technique.
Variations worth knowing
| Variation | Difficulty | What it changes |
|---|---|---|
| Bodyweight windmill | Easiest | Warm-up drill, no load |
| Low windmill | Easy | Weight in the bottom hand, no overhead demand |
| Half-kneeling windmill | Moderate | Removes the hamstring limit, teaches the rotation |
| High windmill | Moderate | The standard overhead version |
| Double windmill | Hard | One weight overhead, one in the lower hand |
| Bottoms-up windmill | Very hard | Kettlebell held upside down, extreme grip and stability demand |
The half-kneeling windmill deserves a mention. Kneeling on the knee beneath the weight takes hamstring flexibility out of the equation, which lets people with tight hamstrings practise the hip shift and rotation properly. Our kneeling exercises guide explains how to set that position up.
Windmill versus similar exercises
| Exercise | Main quality trained | How it differs |
|---|---|---|
| Windmill | Hinge with rotation, overhead stability | Slow, controlled, one arm fixed overhead |
| Turkish get-up | Full-body stability through many positions | Longer, more complex, moves from floor to standing |
| Side bend | Lateral flexion | Bends the spine sideways rather than hinging |
| Windshield wiper | Rotation of the legs against a fixed torso | Done lying or hanging, no hinge |
| Suitcase carry | Resisting side bend while walking | No rotation, much easier to learn |
If the windmill appeals because of the rotational work, the windshield wipers exercise trains rotation from the other end of the body.
The bottom line
The windmill is a hip hinge with a rotation, performed underneath an arm that stays still. Get that picture right and the exercise makes sense. Treat it as a side bend and it becomes a reliable way to annoy your lower back.
Start with the bodyweight version and use it as a warm-up. Move to the low windmill to load the hinge, then put a light weight overhead and keep your eyes on it. Stay at 3 to 5 slow reps per side, twice a week, near the start of your session.
And resist the urge to load it quickly. A windmill done slowly with a light weight builds exactly what it is meant to: hips that move, obliques that control rotation, and a shoulder that stays stable while everything else shifts around it.
The windmill is one of twelve exercises in our kettlebell ab workout.
Frequently asked questions
What muscles does the windmill exercise work?
The obliques, glutes and hamstrings do most of the work, with the rotator cuff and deltoid holding the overhead arm stable. The spinal erectors, quadratus lumborum, lats and adductors assist. It combines a hip hinge with rotation, so it trains mobility and stability together rather than isolating one muscle.
Is the windmill exercise good for beginners?
The bodyweight version is, and it makes an excellent warm-up. The loaded overhead version needs a clean hip hinge and good overhead shoulder range first, so beginners should spend two to three weeks on the unloaded movement and then use the low windmill, with the weight in the bottom hand, before going overhead.
Can I do windmills with a dumbbell instead of a kettlebell?
Yes. A dumbbell works well and is easier to load in small steps. Keep a firm grip with your wrist straight and stacked over your elbow and shoulder, and follow the same technique. A kettlebell sits a little more comfortably overhead at heavier weights, but it is not essential.
How heavy should a windmill be?
Light. Start with no weight, then 4 to 8 kg, and build to 8 to 12 kg only when the overhead arm stays vertical on every rep. The limit is shoulder stability and control rather than strength, so a slow windmill with a light weight is far more useful than a shaky heavy one.
How many windmills should I do?
Three sets of 3 to 5 slow reps per side for the loaded version, twice a week. For the bodyweight warm-up version, 10 to 15 reps per side is fine and can be done daily. Place loaded windmills early in a session, since they need concentration and should not be done when fatigued.
Why does my lower back hurt during windmills?
Usually because you are bending through your spine instead of hinging at the hips. Push the hip on the weighted side back and out, keep your spine long, and stop where your hamstrings limit you. Reaching for the floor by rounding the back is the most common cause of strain.
Are windmills bad for your shoulders?
Not if you have the overhead range and keep the arm vertical. Problems arise when the arm drifts forward, the elbow bends or the weight is too heavy. Anyone with a current shoulder injury or a history of dislocation should avoid the overhead version and use the low windmill instead.
What is the difference between a windmill and a Turkish get-up?
The windmill is a single standing movement, a hinge and rotation under a fixed overhead arm. The Turkish get-up is a longer sequence that takes you from lying on the floor to standing and back, passing through several positions. Both build overhead stability, and the windmill is the simpler one to learn.
