A stability ball — you may know it as a Swiss ball, exercise ball or Pilates ball — is one of the few pieces of home equipment that genuinely earns its space when you have a sore lower back. Not because sitting on one at your desk will fix your posture (it won’t, and it usually just makes you tired), but because it does two things a mat cannot. It supports your body in positions that would otherwise load the spine, and it adds a small, controllable wobble that forces the deep core and hip muscles to switch on and stay on. Used well, that combination builds exactly the kind of quiet, reliable trunk control that a painful back is missing. Below are the eight ball exercises I use most, with the cues that make them work.
Key takeaway: The most useful Pilates ball exercises for lower back pain are the ball glute bridge, ball wall squat, ball dead bug, ball bird dog, ball hamstring curl, ball back extension, kneeling ball roll-out and ball side-lying clam. Keep the spine neutral throughout, move slowly, and let the ball’s instability work your deep core rather than fighting it. Consistency over eight weeks matters more than any single move.
The best Pilates ball exercises for lower back pain use the ball to support the body and add gentle instability while the spine stays neutral: the ball glute bridge (shoulders on the ball), ball wall squat, ball dead bug, ball bird dog, supine ball hamstring curl, ball-supported back extension, kneeling ball roll-out and ball-supported side-lying clam. Each strengthens the deep abdominals, glutes and hips that protect the lumbar spine, and the wobble of the ball trains the trunk to stay steady under load. Sophie Mercer, PMA-certified clinical Pilates instructor, designed an 8-week Lower Back Pain protocol of 34 exercises that builds this stability progressively at home.
Can exercise balls help with lower back pain?
They can, and the reason is worth understanding, because it tells you how to use the ball properly.
Persistent lower back pain is rarely a problem of weakness alone. More often the back muscles are working overtime while the deep abdominals, glutes and hips are underworking, so the lumbar spine takes load it should not. A stability ball helps in two ways. First, support: lying with your shoulders or hips on the ball puts you in positions where the glutes and hamstrings can work hard while the spine is held rather than loaded. Second, instability: the ball moves a little with every rep, and your deep stabilisers have to react to keep the spine still. That reactive control is the skill you need when you step off a kerb or lift a shopping bag.
What the ball does not do is fix anything passively. Sitting on it all day just makes you tired and often makes back pain worse. It is an exercise tool, and it rewards slow, controlled work. This is the same principle behind the exercises in Pilates for lower back pain, just with an added surface.
Choosing a ball: when you sit on it, hips and knees should be at roughly 90 degrees. For most people that is a 55 cm ball under about 165 cm tall, a 65 cm ball up to around 185 cm, and 75 cm above that. Inflate it firmly — a soft ball makes everything harder and less stable.
8 Pilates ball exercises for lower back pain
Work through these two or three times a week. Do them slowly, in the order given, and stop any exercise that increases back pain or sends pain into a leg.
1. Ball glute bridge (shoulders on the ball) Sit on the ball, walk the feet forward until your shoulders and head rest on it and the hips are low. Press through the heels to lift the hips until shoulders, hips and knees form a straight line. Hold 2 seconds, lower 3 counts. 10-12 reps. Feel: glutes and hamstrings. Avoid: pushing the hips above the line into an arched back; ribs flaring.
2. Ball wall squat Place the ball between your lower back and a wall, feet slightly forward. Slide down until thighs are roughly parallel, or as far as is comfortable, then press back up. 10-12 reps. Feel: thighs and glutes, with the lower back gently supported. Avoid: letting the knees drift inward, or leaning back into the ball rather than standing tall through the trunk.
3. Ball dead bug Lie on your back holding the ball between your hands and knees, pressing gently into it. Lower one heel toward the floor and the opposite arm overhead while the other limbs keep squeezing the ball. Return and swap. 8 each side. Feel: deep abdominals, lower back heavy on the floor. Avoid: the back arching off the mat — shorten the range if it does.
4. Ball bird dog Lie face down over the ball with hands and feet on the floor, ball under the hips and lower ribs. Reach one arm and the opposite leg away until they are level with the body. Hold 3-5 seconds. 8 each side. Feel: deep abdominals, glute of the lifted leg. Avoid: lifting the leg above hip height into an arch; rolling on the ball.
5. Supine ball hamstring curl Lie on your back, heels on the ball, legs straight. Lift the hips into a bridge, then bend the knees to draw the ball toward you and push it back out while the hips stay lifted. 8-10 reps. Feel: hamstrings and glutes working hard. Avoid: the hips dropping as the ball comes in, or the lower back arching as it goes out.
6. Ball-supported back extension Lie face down over the ball, hips on the ball, feet wide against a wall or skirting board. Hands by the temples. Lift the chest until the body is a straight line — no higher. Lower slowly. 8-10 reps. Feel: the muscles either side of the spine and the glutes. Avoid: lifting into a big arch, or jerking. Skip this exercise if extension aggravates you (it usually does for spinal stenosis).
7. Kneeling ball roll-out Kneel with forearms on the ball, hips stacked over knees. Roll the ball forward a few inches by reaching the arms away, keeping the spine neutral and ribs drawn in, then pull back. 8-10 reps. Feel: deep abdominals bracing. Avoid: the lower back sagging or the hips sitting back — go only as far as you can hold neutral.
8. Ball-supported side-lying clam Lie on your side, knees bent, with the ball between your feet or (harder) held against the top knee for resistance. Lift the top knee while the pelvis stays stacked. 12-15 each side. Feel: the side of the hip. Avoid: rolling the pelvis backward to lift higher.
If you sit at a desk all day, pair these with the routine in Pilates exercises for desk workers — desk-related back pain usually comes with tight hip flexors, which the ball work alone will not release.
What are the big 3 exercises for lower back pain?
The “big three” is a widely taught set of spine-stabilisation exercises: the modified curl-up, the side plank and the bird dog. The idea behind them is that a painful back needs a trunk that can stay stiff and neutral while the arms and legs move — endurance rather than range. All three are in my programmes, and all three transfer neatly to the ball once the floor versions feel easy: the ball bird dog above, a side plank with the forearm on the ball, and a curl-up with the lower back supported on the ball. Do the floor versions first; the ball is a progression, not a starting point.
How effective is Pilates for lower back pain?
Among exercise approaches for persistent, non-specific lower back pain, Pilates is one of the better supported, and the reason is that it trains exactly what the guidelines recommend: graded, active exercise that restores control and confidence rather than resting the back. Most people notice changes within a few weeks of consistent practice — easier mornings, less stiffness after sitting — with more substantial gains over two to three months. I go through realistic timelines in how long does Pilates take to work for lower back pain. The one caveat: effectiveness depends on structure. Two or three ball exercises done when you remember will not do much. A planned progression, three or four sessions a week, will.
What is the number one exercise for lower back pain?
If there is one, it is the glute bridge in neutral spine — and exercise 1 above is the best version of it for most people, because the ball supports the upper body and lets the glutes work through a fuller range. It teaches hip extension without arching the back, strengthens the muscles that are almost always underworking in a painful back, and is safe during all but the sharpest flares. But I would be doing you a disservice if I let you stop there. Bridge, bird dog and side plank together, done consistently, will outperform any single exercise.
When to see a clinician
Ball exercises are gentle, but stop and get assessed if your back pain comes with numbness, tingling or weakness in a leg, pain radiating below the knee, any change in bladder or bowel control, or pain that does not ease with rest and position change. If you know or suspect a disc problem, the more specific guidance in exercises for a herniated disc should come first.
How the Lower Back Pain protocol helps
Sophie’s 8-Week Lower Back Pain Program puts the ball exercises above into a structure: 34 exercises across eight weeks that begin with neutral-spine control and glute activation, then progress the stability work — bridges, bird dogs, side planks, hinges — so the back becomes steadily stronger and more confident. It needs only a mat, with the ball as an optional progression. If your pain is tied to long hours at a desk, the 6-Week Desk Workers with Lower Back Pain programme addresses the hip flexors and posture alongside the core, and the 6-Week Posture Correction programme is the next step once the pain has settled.

Lower back pain has many possible causes; if your pain is severe, radiates down the leg, comes with numbness or weakness, or does not improve with a few weeks of sensible exercise, please consult a physiotherapist or doctor before continuing.
