A bulging disc is one of the most common findings on a spinal scan, and one of the most frightening phrases to read on a report. It helps to know what it actually means. The discs between your vertebrae have a tough outer ring and a soft centre; a bulge is the outer ring pushing slightly beyond its normal edge, usually backward, without tearing. It is on a spectrum with a herniated disc, where the centre pushes through the ring. Both are common, both are often painless, and both tend to settle over months with the right movement. Pilates can be a very good part of that recovery — as long as it is the right Pilates, and you know which exercises to leave out.
Key takeaway: Pilates is good for a bulging disc when it is adapted to the disc: neutral-spine core work, gentle extension, hip and glute strengthening, and learning to hinge from the hips. Avoid loaded or repeated flexion — crunches, roll-ups, roll-downs, forward folds — and heavy twisting until the disc has settled. Most people can progress to fuller movement over two to three months.
Pilates is good for a bulging disc when it is adapted to the injury. The helpful exercises keep the spine neutral or gently extended while strengthening the deep abdominals, glutes and hips — bird dog, dead bug, glute bridges, prone forearm press-ups and side-lying leg work — and teach you to hinge from the hips rather than bend through the lower back. The exercises to avoid are loaded or repeated spinal flexion (crunches, roll-ups, roll-downs, forward folds) and heavy twisting, which push the disc backward toward the nerve. Sophie Mercer, PMA-certified clinical Pilates instructor, designed a 12-week Herniated Disc Recovery protocol of 48 exercises that follows this disc-safe progression.
What is a bulging disc, and why does exercise choice matter?
Picture the disc as a jam doughnut. A bulge is the dough spreading outward under pressure; a herniation is the jam coming through. The pressure that spreads it comes mostly from flexion — bending forward — especially when repeated or loaded. Bending pushes the soft centre backward, toward the outer ring and the nerve roots behind it. That is why a bulging disc typically hurts more with sitting, bending, lifting and coughing, and eases with standing and walking.
So the logic of exercise is simple. Reduce the flexion that pushes the disc backward, and build the strength and habits that stop you bending through the lumbar spine in daily life. For the closely related herniated disc, the same principles apply and I go into more depth in exercises for a herniated disc.
What exercise is best for a bulging disc?
These are the Pilates exercises I start with for a bulging lumbar disc. Do them daily if they feel good; stop any exercise that sends pain further down the leg.
- Prone forearm press-up (sphinx) — lie face down, prop on the forearms, let the lower back relax into a gentle arch. Hold 30-60 seconds, breathing slowly. Feel the pressure ease or move toward the spine; stop if pain moves further down the leg.
- Prone breathing / prone lying — simply lying face down for 2-3 minutes is a valid exercise for a bulging disc, and a good place to begin if press-ups feel too much.
- Bird dog — on hands and knees, spine neutral, reach one arm and the opposite leg away without the pelvis tipping. Hold 5 seconds, 8 each side. Feel the deep abdominals and glute; avoid arching or sagging.
- Dead bug — on your back, knees over hips, lower one heel toward the floor and the opposite arm overhead. 8 each side. The lower back stays quiet and heavy; if it arches, shorten the range.
- Glute bridge — knees bent, feet flat, lift the hips to a straight line from shoulders to knees. 10-12 reps. Feel glutes and hamstrings, not the lower back.
- Side-lying leg lifts — lie on your side, top leg straight, lift and lower slowly. 10-12 each side. Strengthens the hip muscles that stabilise the pelvis.
- Supine heel slides — on your back, slide one heel away and back while the pelvis stays perfectly still. 8-10 each side. The simplest deep-core exercise there is.
- Standing hip hinge — feet hip-width, hands on hip creases, fold forward from the hips with a flat back and return. 8-10 reps. This is the movement that protects your disc every time you bend to pick something up.
- Walking — 10-20 minutes, twice a day if you can. Walking gently pumps the disc and is consistently one of the best things for a settling back.
Notice what is missing: nothing rounds the spine under load. That is deliberate.
What exercises should be avoided with bulging discs?
Pilates has a strong flexion tradition — the classical mat sequence rounds the spine repeatedly — and this is where a general class can go wrong for a bulging disc. Until your back has settled, avoid:
- Roll-up, roll-over and roll-down — sustained loaded flexion
- The Hundred with the head lifted — if it aggravates you, do it with the head down
- Crunches, sit-ups and ab curls
- Rolling like a ball, seal, open-leg rocker — rolling on the spine compresses and flexes it repeatedly
- Seated forward folds and spine stretch forward
- Saw, criss-cross and loaded twists — rotation combined with flexion is the most provocative combination for a disc
- Jack-knife, corkscrew and other overhead inversions
- Heavy hamstring stretches with a rounded back — stretch the hamstrings lying on your back with a strap instead
Not every one of these will hurt every person, and many can come back later. But during the first two to three months there is no benefit that outweighs the risk. For the debate about the two main approaches to disc rehab, see Pilates vs the McKenzie method for a herniated disc. If your bulging disc is producing leg pain, the exercise selection in Pilates exercises for sciatica is the next step.
What is the best therapy for bulging discs?
For the large majority of bulging discs the best therapy is conservative and active. Clinical guidelines consistently recommend staying active, graded exercise, and education about the condition over bed rest, early scans, or early injections. The pattern most people follow looks like this:
- Calm it down (weeks 1-3). Prone lying, gentle extension, walking, and avoiding provoking postures — especially long sitting.
- Build support (weeks 3-8). Neutral-spine core and hip strengthening, hinge training, and gradually longer walks.
- Restore full movement (weeks 8-12 and beyond). Gentle, unloaded flexion is reintroduced, then rotation, then loaded work, so that you are not left with a back that is strong but fearful of bending.
Manual therapy, heat and short courses of pain relief can support this, but they are not the treatment; the exercise is. Injections and surgery are for persistent nerve symptoms that do not improve, not for a bulge on a scan.
Which is better for back pain, yoga or Pilates?
For a bulging disc specifically, Pilates has the edge, and it is not really about one discipline being superior. Pilates is built around neutral-spine stability, controlled strength and precise cueing, which maps neatly onto disc rehab. Many yoga flows, by contrast, are heavy on deep forward folds, seated twists and repeated sun salutations — exactly the movements a bulging disc dislikes. Yoga’s breathing work and gentle backbends like sphinx and cobra are genuinely helpful, and once the disc has settled a thoughtful yoga practice is fine. The class label matters far less than whether the teacher understands discs. I compare the two in more detail in Pilates vs yoga for back pain.
When to see a clinician
See a doctor or physiotherapist before exercising if your bulging disc comes with numbness, tingling or weakness in the leg or foot, pain that travels below the knee, or pain that is not improving after a few weeks. Seek urgent care for any change in bladder or bowel control, numbness around the saddle area, or weakness in both legs. These are uncommon, but they are the situations where exercise alone is not the answer.
How the Herniated Disc Recovery protocol helps
Sophie’s 12-Week Herniated Disc Recovery Program is written for exactly this injury — a bulging or herniated lumbar disc — and follows the three-phase logic above across 48 exercises: calm the disc with extension and neutral-spine work, build core and hip support, then carefully reintroduce flexion and rotation so you finish with a back that is both strong and confident. If your back pain is more general, the 8-Week Lower Back Pain programme is the broader starting point, and if the disc is sending pain down the leg, the 8-Week Sciatica Relief programme addresses the nerve irritation directly.

A bulging disc is usually benign but can occasionally involve nerve compression; if you have leg weakness, numbness, changes in bladder or bowel function, or pain that is not improving, please consult a physiotherapist or doctor before continuing.
