Lower Back Pain: Why Resting Makes It Worse, and the Exercises That Actually Help
'Kamar ka dard' sends half of Pakistan to bed, onto the floor and into an MRI scanner. Most of that makes it worse. Here is what back pain usually is, why scans mislead, what the biggest reviews say about exercise, a gentle starter plan, and the warning signs that need a doctor today.

In Pakistani homes the advice for 'kamar ka dard' is almost always the same: lie down, don't bend, sleep on the floor, and get an MRI. The scan then shows a 'disc bulge', and from that day the person is afraid to lift a bucket. Almost every part of that advice is the opposite of what the research supports. Back pain is miserable, but in most cases the back is not damaged, and moving is how it recovers.
Most back pain is not serious
Around nine in ten cases are 'non-specific' low back pain: real pain, but not caused by a fracture, infection, tumour or nerve compression that needs surgery. The UK's NICE guideline on low back pain recommends staying active, exercise and reassurance, and advises against routine imaging, because what a scan shows rarely changes treatment.
Why scans mislead
A 2015 review in the American Journal of Neuroradiology pooled scans from 3,110 people who had no back pain at all. 'Degenerative' findings that sound alarming on a report were everywhere — and became more common with age, like grey hair.
| Finding | At age 20 | At age 80 |
|---|---|---|
| Disc degeneration | 37% | 96% |
| Disc bulge | 30% | 84% |
| Disc protrusion | 29% | 43% |
| Annular fissure (small tear) | 19% | 29% |
So a disc bulge on your report may have been there for years before the pain started, and it is not a reason to stop moving. Scans are useful when red flags are present or surgery is being considered — not as a first step.
Rest or stay active?
A Cochrane review comparing advice to rest in bed with advice to stay active found that, for new back pain, staying active gave small improvements in pain and function; for sciatica, the two were about the same. Bed rest helps nothing beyond a day or two of easing the worst, and weeks of lying down weaken the very muscles that support the back.
Exercise for back pain that lasts
For pain lasting more than three months, the 2021 Cochrane review is the largest body of evidence: 249 trials. Exercise reduced pain by about 15 points on a 100-point scale compared with no treatment, usual care or placebo — a clinically important difference — and improved function. A 2020 network meta-analysis of 89 trials in the British Journal of Sports Medicine compared exercise types head to head. Pilates ranked best for pain; strength training and motor-control ('core stability') exercise ranked best for function; strength and aerobic exercise helped mood. Stretching and McKenzie exercises on their own did no better than no treatment.
The practical message: the type matters less than doing something that loads the back and hips progressively, regularly, for weeks.
A gentle starter plan
| Exercise | Sets × reps | How |
|---|---|---|
| Walking | 10–30 minutes daily | Start with what is comfortable and add a few minutes each week |
| Glute bridge | 3 × 10–15 | Lying on your back, squeeze the buttocks to lift the hips; lower slowly |
| Bird dog | 3 × 8 each side | On hands and knees, reach one arm and the opposite leg out, back level |
| Dead bug | 3 × 8 each side | Lying on your back, lower opposite arm and leg slowly, lower back gently pressed down |
| Side plank from the knees | 3 × 20–30 seconds each side | Hips lifted in a straight line |
| Sit-to-stand from a chair | 3 × 10 | Stand up and sit down with control; lower the chair as it gets easy |
| Hip hinge with a broomstick | 3 × 10 | Push the hips back with a straight back; later a light dumbbell Romanian deadlift |
| Band row | 3 × 12 | Band round a door handle or pillar, pull elbows back, squeeze shoulder blades |
A useful rule from physiotherapy: some discomfort during exercise is acceptable — up to about 3 out of 10 — as long as it settles by the next morning and is not getting worse week to week. If an exercise sharply increases the pain or sends it down the leg, swap it for an easier version. Add reps, then load, every week or two.
Myths that keep backs sore
- "Never bend or lift again." Gradually returning to bending and lifting is part of recovery; a strong back is a loaded back.
- "Sleep on the floor." There is no evidence the floor is better. Sleep on whatever lets you rest comfortably.
- "A disc bulge is permanent damage." Many bulges shrink over time, and many people with them have no pain.
- "Bad posture caused it." No single posture is 'correct'; staying in any position too long is the problem. Move often.
- "Just strengthen your core." It helps, but whole-body strength, walking and activity you enjoy matter as much.
For desk workers
Long hours of sitting are a common trigger. Get up and walk for a few minutes every 30–60 minutes, keep the screen at eye level, and use the plan above on two or three days a week. Our desk-job guide has a full working-day routine.
Red flags: see a doctor urgently
- Numbness in the groin or around the back passage, or new trouble controlling the bladder or bowels.
- New weakness in a leg or foot, or numbness that is spreading.
- Fever, feeling unwell, or unexplained weight loss.
- A history of cancer, a significant fall or accident, or long-term steroid use.
- Pain that is severe at night and does not ease with rest or any position.
See a doctor or physiotherapist soon — not urgently — if the pain is not improving after about six weeks, if sciatica down the leg is getting worse, or if you are unsure what is safe for you.
This article is general information, not medical advice. Get your back pain assessed by a doctor or physiotherapist, especially if it followed an injury or you have any of the red flags above, and stop any exercise that causes sharp or spreading pain.
Frequently Asked Questions
What is the best exercise for lower back pain?
There is no single best one. In a 2020 network meta-analysis, Pilates ranked best for pain and strength training and motor-control exercise best for function. What matters most is doing exercise that progressively loads the back and hips — bridges, bird dogs, sit-to-stands, hip hinges, rows — two or three times a week, plus daily walking.
Should I rest or exercise with back pain?
Keep moving. A Cochrane review found that advice to stay active gave small improvements over bed rest for new back pain, and for long-lasting pain exercise reduced pain by about 15 points on a 100-point scale in 249 trials. A day or two of easing off is fine; weeks of rest are not.
Is walking good for lower back pain?
Yes. Walking is one of the easiest ways to stay active with back pain. Start with what is comfortable, even 10 minutes, and add a few minutes each week. Combine it with strengthening exercises for the best results.
Do I need an MRI for back pain?
Usually not. Scan findings such as disc bulges are common in people with no pain at all — 30 percent at age 20 and 84 percent at age 80 — so they often do not explain the pain. Scans are useful when red flags are present or surgery is being considered.
Can I lift weights with back pain?
Often yes, with sensible progression. Strength training ranked among the best options for back function in trials. Start light with good technique, keep discomfort to a mild level that settles by the next day, and build up gradually. Get advice first if you have sciatica, weakness or red-flag symptoms.
When is back pain an emergency?
Seek urgent care for numbness around the groin or back passage, new loss of bladder or bowel control, new leg weakness, fever or feeling unwell, unexplained weight loss, a history of cancer, or back pain after a significant fall or accident.
