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. But the type of exercise matters. The internet is full of back pain advice — much of it contradictory, some of it actively counterproductive. This guide sticks to what the evidence actually supports.

Why most generic 'core exercises' miss the mark

Traditional core exercises like sit-ups, crunches, and even many Pilates movements focus on the superficial abdominals — the rectus abdominis and obliques. These muscles generate movement and produce force, but they do relatively little for spinal stability in the way that matters for back pain. The muscles that protect the spine — the transversus abdominis, multifidus, and pelvic floor — work best when trained to maintain a neutral spine under load, not when contracting maximally through a full range of motion.

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.
• 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

Why a one-size approach doesn't work

The exercises above are a solid starting point, but back pain has multiple potential drivers — disc, facet joint, SI joint, muscle, nerve — and the best exercise program depends on which structures are involved. A physiotherapy assessment identifies the likely source and tailors the program accordingly, which is why people who see a physio recover faster than those following generic internet advice.
