The Best Exercises for Lower Back Pain, Backed by Research

Lower back pain is the world's leading cause of disability, and exercise is one of the most effective treatments available. The good news is that around 90% of cases resolve within six to twelve weeks without surgery or injections. But the type of exercise matters. The internet is full of back pain advice, much of it contradictory and some of it actively counterproductive. This guide sticks to what the evidence actually supports, starting with what to do in the first few days.

In the first few days: keep moving

Bed rest is one of the worst things you can do for acute back pain. People who stay as active as their pain allows recover faster than those who rest. Movement keeps the discs hydrated, prevents the muscles from tensing up further, and tells your nervous system that the back is safe. You don't need to push through sharp, worsening pain, but gentle walking, light stretching, and continuing normal activities as much as possible is protective, not harmful.

In most cases of acute lower back pain there is no serious structural damage. The pain is real, but it often comes from protective muscle spasm, sensitised nerve endings, or a minor disc irritation, all of which are temporary and reversible. Knowing this genuinely helps; catastrophic thinking about 'something being out' prolongs recovery.

• Take anti-inflammatories if tolerated and not contraindicated (check with your GP or pharmacist)
• Apply heat after the first 24 hours: warmth reduces muscle spasm and improves circulation
• Walk for 10 to 15 minutes every few hours rather than sitting or lying for long stretches
• Sleep with a pillow between your knees if on your side, or under your knees if on your back
• Break up prolonged sitting every 30 to 45 minutes

Why crunches and generic 'core exercises' miss the mark

The core is primarily a stabilisation system, not a movement system. Its job is to create a stable base from which the limbs can move. Traditional core exercises like sit-ups, crunches, and many Pilates movements train the superficial abdominals (the rectus abdominis and obliques), which are already over-recruited in most people with back pain. Crunches also increase pressure inside the disc significantly, exactly the opposite of what you want with disc-related pain. The muscles that protect the spine (the transversus abdominis, multifidus, and pelvic floor) work best when trained to hold a neutral spine while the limbs move under load.

The exercises with the strongest evidence

These movements consistently outperform alternatives in clinical trials for chronic and recurrent low back pain:

• Dead bug: lying on your back, extending opposite arm and leg while maintaining lumbar contact with the floor. Trains deep stabilisers without loading the spine.
• Bird dog: on hands and knees, extending opposite arm and leg while keeping the pelvis level. Trains the multifidus and gluteals simultaneously.
• Side plank: works the lateral stabilisers (quadratus lumborum and obliques) which are chronically underloaded in most people with back pain.
• Pallof press: standing side-on to a cable or band and resisting the rotational pull. Trains the trunk to resist movement rather than create it.
• Glute bridge: activates the gluteus maximus and reduces reliance on the lumbar extensors. Particularly useful for people who feel their back muscles doing the work their glutes should be doing.
• Hip flexor stretch: shortened hip flexors (common from prolonged sitting) increase anterior pelvic tilt and load the lumbar facet joints. A sustained hip flexor stretch is one of the quickest ways to relieve low back stiffness.

Progressive loading: the step most people skip

The exercises above are starting points, not endpoints. The evidence is clear that progressive resistance training, gradually increasing the load the back is exposed to over weeks and months, is far more effective for long-term outcomes than staying with gentle exercises indefinitely. Once the basics are established, progressing to deadlifts, Romanian deadlifts, and loaded carries builds the kind of spinal resilience that prevents recurrence.

What to avoid

• Sit-ups and crunches: increase disc pressure and are rarely helpful for back pain
• Sustained forward bending when stiff: can irritate the posterior disc and facet joints in acute flare-ups
• Complete rest: bed rest consistently makes back pain worse in the evidence. Keep moving.
• High-impact exercise in acute pain: wait until the acute phase settles before returning to running or jumping

When to see a physio

If pain is severe and not improving after three or four days, if it's radiating down the leg, or if you have any numbness, tingling, or changes to bladder or bowel function, get assessed promptly. Otherwise, an assessment within the first week is useful to confirm there's nothing serious and to get a clear plan. Back pain has multiple potential drivers, including disc, facet joint, SI joint, muscle, and nerve, and most people with persistent pain also have restrictions elsewhere such as tight hips or a stiff thoracic spine. A physiotherapy assessment identifies the likely source and tailors the program accordingly, rather than prescribing the same generic routine to everyone.
