Saving Your Back at the Wheel
The standard throwing posture is a person curled into a C shape over a spinning wheel for two hours. It is the most common injury in pottery, it arrives slowly enough that nobody connects it to anything, and it is almost entirely a setup problem rather than a fitness one.
If you are hunched over the wheel, the wheel is too low or your seat is. Raise one or both until your back is straight, sit with your feet flat, get up every half hour, and use a mirror instead of leaning in to look.

It is the furniture, not you
Wheels are built at a height that suits a manufacturer, and stools are whatever the studio had. The two together decide your posture before you sit down.
If your back is rounded over the wheel, that is a geometry problem. Your hands have to reach the clay, and if the clay is too low, your spine makes up the difference for two hours.
Raise the wheel, raise yourself, or both. Nearly everything else on this page is detail next to that.
The setup, in order
- Sit down and put your hands on the wheel head. Look at your back. If it is rounded, something has to change.
- Raise the wheel first. Blocks, bricks, a purpose-made stand. This is the fix that works for most people.
- Then set the seat so your feet are flat on the floor and your hips are a little above your knees.
- Sit back, not perched. If the stool has a back, use it. If not, sit on your sitting bones rather than the edge.
- Get close. Reaching across a gap to the wheel is what bends you forward. Move the stool in.
- Put a mirror opposite you so you can see the pot's profile without leaning over it.
- Stand up every half hour. Set a timer if you forget, which you will.
Three things people get wrong
Treating it as a fitness problem
Core strength helps, and it does not fix a wheel that is six inches too low. Change the setup first, then think about the rest.
Accepting whatever the last person left
Studio wheels and stools get moved constantly. Checking the height takes ten seconds and almost nobody does it, which means most people throw at somebody else's settings.
Not noticing until it hurts
Back trouble from throwing builds over months, so there is no moment that feels like an injury. By the time it is obvious, it has been happening a long time.
Why the standard posture hurts
- The clay is below your hands and in front of you. To reach it with any force, you have to bring your shoulders forward and down, and the spine rounds to allow it.
- You hold that position still. Static load is harder on a back than movement is. Two hours in one shape is worse than two hours of varied work.
- Centering pushes you further in. The one move where you deliberately lean your body weight into the clay is also the move with the worst posture attached.
- Looking at the pot pulls you down again. You lean in to see the profile, then stay there, and the leaning becomes the posture rather than a glance.
- Perching on a stool takes the support away. Sitting on the front edge with legs splayed leaves your lower back holding your whole upper body unassisted.
- It builds without an event. There is no moment of injury, which is why people put it down to age or a bad night's sleep rather than to the wheel.
The reassuring part
Nearly all of that is geometry. Move the clay closer to your hands and the reason to round your back disappears, and the position you would naturally sit in is the one that does not hurt.
The setup that fixes most of it
Six adjustments, none of which cost anything, in the order they matter.
Raise the wheel
The big one. Concrete blocks, a sturdy platform, or a purpose-made stand. Most wheels are built low, and raising the wheel head by even a few inches changes the whole posture. Do this before anything else.
Set the seat height second
Feet flat on the floor, hips slightly above knees. If raising the seat lifts your feet off the ground, you need a footrest, not a higher stool.
Sit back on your sitting bones
Not perched on the front edge. A seat with a back that you actually lean against is better than any amount of remembering to sit up straight.
Get close to the wheel
A gap between you and the wheel is a gap your spine has to bridge. Move the stool in until you can work with your upper arms near your body.
Brace your elbows
Into your thighs or against your ribs while centering. That turns a back-and-arm job into a skeleton job, and it is better technique anyway.
Check it every time
Studio wheels and stools move. Ten seconds at the start of a session beats three hours at somebody else's settings.
Throwing standing up
Less common in the West, completely normal elsewhere, and the option most likely to solve a back that has stopped responding to smaller fixes.
- It removes the fixed position. Standing, you shift your weight constantly without thinking about it, which is exactly what a back wants.
- You lean from the hips instead of the spine. There is still some forward lean, and it hinges at the hip rather than rounding the lower back.
- It needs a much higher wheel. Roughly waist height, which means a stand or a platform rather than an adjustment.
- Centering is easier standing. You can put your body weight over the clay rather than pushing horizontally at it, which is why some people switch for that alone.
- Your legs and feet take the day instead. A mat helps, and it is a different kind of tired rather than no tiredness at all.
- You need a foot pedal you can reach. The usual awkwardness, and it is solvable with a block or a longer cable.
Worth trying before committing
Raise a wheel onto blocks for one session and see how it feels. Standing suits some people immediately and others not at all, and an afternoon tells you which you are.
The mirror, and why you lean
A lot of the leaning at a wheel is not about force at all. It is about looking. You bend in to see the profile of the wall, then you stay bent because you are still working.
- Stand a mirror on the far side of the wheel, facing you, at roughly wheel height.
- You see the silhouette instead of the top edge. Looking down at a pot from above tells you almost nothing about its profile.
- It is a more honest view. Up close and from above, a form looks different from how it will look on a shelf. The mirror shows you the real shape.
- Your head stays up, which keeps your shoulders back, which keeps your spine where you want it.
- Any mirror works. A cheap tile mirror propped against something. This is not equipment, it is a mirror.
The side effect
Most people find their forms improve. Judging a curve from a silhouette is simply better information than judging it from above, which is why a mirror is worth having even if your back is fine.
Habits that cost nothing
- Stand up every half hour. Not a break, just a change. Put a pot on a shelf, fill a bucket, walk to the sink.
- Warm up before the first center. Centering cold, first thing, is the highest-load moment of the day and the worst time to do it unprepared.
- Do the heavy throwing early. Posture slips when you are tired, and slipped posture under load is the combination that hurts.
- Alternate throwing with something standing. Trimming, glazing, wedging. Two shorter sessions beat one long one.
- Notice where the ache is. Lower back is usually posture. Between the shoulder blades is usually reaching. They have different fixes.
- Stretch afterward, not just before. Even a minute of opening your chest and hips counteracts the shape you just spent two hours in.
The rest of the session
Throwing gets the blame, and a fair share of pottery back trouble happens standing up.
Lifting clay
Legs, not back, and split a bag rather than carrying a whole one awkwardly. A wire through the bag on the table takes five seconds.
Full buckets
Worse than clay bags, because the weight moves as you carry it. Half fill them and make two trips.
Wedging table height
Around hip height. Too low and you bend for the whole job; too high and you cannot get any weight into it. This is the second most common height problem after the wheel.
Loading low shelves
Squatting with a loaded ware board held out in front of you is a bad combination. Put the board down, then move the pots.
Reaching into a kiln
Bending forward over a rim with your arms extended is one of the worst positions in the studio. Kneel rather than bend, and take fewer pieces at a time.
Standing at a sink
Low sinks put you back in the same rounded shape. Widen your stance to drop your height rather than bending your spine.
What people get wrong
Buying a better stool before raising the wheel
The wheel height is the bigger lever. A great stool at a low wheel still has you reaching down.
Remembering to sit up straight
Nobody can hold a posture by willpower for two hours while concentrating on a pot. Change the furniture so the good position is the easy one.
Blaming fitness
Strength helps and it is not the cause. Plenty of very fit people have sore backs from throwing, because the geometry does not care.
Only stretching before
The damage is the two hours in one shape. Something afterward that opens the chest and hips does more than a warmup alone.
Pushing through the last pot
The end of a session is when posture is worst and fatigue is highest. That is where most of the harm concentrates.
Waiting to see if it settles
Pain that persists past a session is worth a doctor rather than another month of working around it. Early is far easier to fix.
The ones that come up at the tables
Why does my back hurt after throwing?
Almost always because the wheel is too low for you, so your spine rounds to get your hands to the clay, and then holds that shape for an hour. It is a setup problem far more often than a fitness one.
What is the single most effective change?
Raise the wheel. Blocks, a platform, a purpose-made stand. Most wheels are built low, and lifting the wheel head a few inches changes your whole posture without you having to remember anything.
How high should the seat be?
High enough that your hips sit a little above your knees, with your feet flat on the floor. If raising the seat lifts your feet off the ground, add a footrest rather than going back down.
Should I try throwing standing up?
It is worth one session to find out. Standing removes the fixed seated position, lets you lean from the hips, and makes centering easier because you can put your weight over the clay. It needs a much higher wheel, and your legs take the day instead.
Does a mirror really help?
Yes, for two reasons. It stops you leaning in to see the profile, which is a large share of the bending nobody notices. And it shows you the silhouette, which is better information about the form than looking down from above.
Will core strength fix it?
It helps and it is not the fix. A strong back still ends up rounded if the clay is six inches below where your hands want to be. Change the geometry first, then the rest is a bonus.
How often should I get up?
Every half hour or so, and it does not need to be a real break. Put a pot on a shelf, refill a bucket, walk to the sink. The problem is holding one shape, so changing shape is the cure.
When should I see somebody about it?
When it persists past a session, or when the same ache turns up every time. Early back trouble responds well to small changes and badly to being ignored for a year. A doctor or physiotherapist is the right call rather than another month of working around it.

The thing that makes this injury so common is that nothing about it feels like a mistake. You sit at a wheel the way everyone sits at a wheel, you have a good afternoon, and six months later your back is a problem you blame on your age.
The fix is almost insultingly small. Check the wheel height and the seat height before you start, the way you would adjust a car seat. If your back rounds when your hands reach the clay, raise something. Then get up every half hour, and put a mirror on the far side so you stop leaning in to look.
If your back rounds at the wheel, the wheel is too low. Raise it, set the seat so your feet are flat, sit close, use a mirror, and stand up every half hour.
