For everyday lower back pain, the three stretches most commonly suggested are the knee-to-chest stretch, cat-cow and child's pose, each held gently for 20–30 seconds and repeated two or three times. They loosen stiff tissue and settle the guarding reflex that makes a sore back feel locked. What they do not do is fix an underlying cause, so pair them with a gradual return to ordinary movement.
Back pain is close to universal. The World Health Organization reports that low back pain affects 619 million people worldwide and that "LBP is the single leading cause of disability worldwide". Around 90% of cases are classed as non-specific, meaning no single underlying disease is identified. For most people, in other words, the problem is mechanical and it responds to movement.
Why does lower back pain happen in the first place?
Most everyday back pain comes from load rather than damage: muscles and joints asked to do something they were not conditioned for, or asked to hold one position for too long. The National Institute of Arthritis and Musculoskeletal and Skin Diseases notes that back pain usually has several overlapping causes, and that "A desk job may also play a role, especially if you have poor posture or sit all day in an uncomfortable chair".
Three patterns turn up again and again. Long unbroken sitting shortens the hip flexors and lets the glutes go quiet, so the lower back picks up work it was never meant to do alone. Weak deep abdominal and hip muscles leave the spine with less support during ordinary lifting and twisting. And a sudden spike in activity, a house move or a first gym session in two years, loads tissue faster than it can adapt. If your day is mostly seated, our piece on whether sitting cancels out your exercise explains why breaking up the sitting matters as much as the workout itself.
What does a gentle lower back stretch routine look like?
The routine below takes roughly ten minutes and needs only floor space. Move slowly, breathe out as you ease into each position, and stay inside a mild stretch rather than chasing range. Sharp or radiating pain is a signal to stop, not to push harder.
- Knee-to-chest. Lie on your back with both knees bent. Draw one knee toward your chest with both hands and hold for 20–30 seconds. Do 2–3 holds per leg, then repeat with both knees together if that feels comfortable.
- Pelvic tilt. Still on your back with knees bent, flatten your lower back gently into the floor by tightening your abdominals. Hold 5 seconds, release fully, and repeat 10 times.
- Cat-cow. On hands and knees, round your back upward as you breathe out, then let it sag gently as you breathe in. Take 3–4 seconds in each direction, for 8–10 slow cycles.
- Lower trunk rotation. On your back with knees bent and feet together, let both knees drop slowly to one side while your shoulders stay on the floor. Hold 15–20 seconds, then change sides. Do 3 holds per side.
- Child's pose. From hands and knees, sit your hips back toward your heels and reach your arms forward along the floor. Hold 30 seconds and repeat 2–3 times, resting briefly between holds.
Once or twice a day is plenty. Many people find the sequence works best as a morning loosener and again after a long seated stretch, rather than as one long session. This is general education, not a programme built for your back: if something here consistently makes symptoms worse, a physiotherapist can assess you in person.
Which exercises help keep back pain from coming back?
Stretching manages the symptom. Strength changes the odds of a repeat. A Cochrane review of exercise for long-lasting low back pain found that "Exercise probably reduces pain compared to no treatment, usual care or placebo", on moderate-certainty evidence. NIAMS points in the same direction, toward strengthening the muscles that support the back to improve mobility and posture.
- Bird-dog. On hands and knees, extend one arm and the opposite leg, hold 5 seconds, and alternate for 8–10 repetitions per side.
- Glute bridge. On your back with knees bent, lift your hips until shoulders, hips and knees line up. Hold 3 seconds, for 10–12 repetitions.
- Dead bug. On your back with arms up and knees over hips, lower one arm and the opposite leg slowly while your lower back stays flat. 8–10 per side.
- Side-lying leg raise. Lift the top leg under control for 10–15 repetitions each side, to build the hip muscles that steady the pelvis.
- Walking. Short, frequent walks are one of the simplest ways to keep a sore back moving without loading it.
Two or three sessions a week is a reasonable starting point, folded into whatever else you already do. Our guide to how much exercise you actually need sets out the weekly targets, and the wider movement guide covers how strength, cardio and mobility fit together.
What should you avoid while your back hurts?
The instinct to lie still is usually the wrong one. NIAMS advice is direct: "Avoid bedrest; instead, limit activities or exercise that cause pain. Gradually increase physical activity as tolerated." A short list of things worth parking for now:
- Extended bed rest. A day of taking it easy is fine. Several days of lying down tend to leave a back stiffer and weaker than it started.
- Heavy or loaded twisting. Deadlifts, heavy rows and rotation under load can wait until symptoms have settled.
- Bouncing toe-touch stretches. Ballistic bobbing at the end of your range irritates tissue rather than lengthening it.
- Full sit-ups and straight-leg raises. Both load the lower spine more than most people expect, and give back little in return.
- Long unbroken sitting. Stand or walk every 30–45 minutes. Short bursts spread through the day, the idea behind movement snacks, suit a sore back better than one big effort.
When is lower back pain a reason to see a doctor?
Most back pain settles by itself, but a small set of signs point to something that needs assessing rather than stretching. NIAMS lists symptoms worth raising with a clinician, including "Weakness, pain, or numbness in your legs", "Trouble urinating", "Fever" and "Weight loss that you did not intend". Read the table below as a prompt to get seen, not as a way to work out what is wrong.
| Warning sign | What to do |
|---|---|
| Numbness, tingling or weakness in one or both legs | Contact a doctor promptly, especially if it is spreading or getting worse |
| Loss of bladder or bowel control, or numbness around the groin and inner thighs | Seek emergency care the same day |
| Back pain that began with a fall, a crash or another significant injury | Get assessed rather than waiting it out |
| Back pain alongside a fever | Contact a doctor promptly |
| Back pain with weight loss you cannot account for | Book a medical review |
| Pain that is severe, steadily worsening, or worst at night and at rest | Book a medical review |
Without those flags, the usual course is encouraging: NIAMS notes that "most people find relief within 6 weeks". If pain is dragging on well past that, is stopping you working or sleeping, or keeps returning every few weeks, that is worth a conversation with a clinician or physiotherapist who can examine you and tailor the loading to what they find.
