Lower back
Lower back stretches, and the half most routines skip
Eight movements the clinically authored Vinys library uses for a stiff, aching lower back, plus what published guidance says belongs alongside the stretching.

What a lower back stretch actually reaches
The lumbar spine is not built to lengthen much. Five thick vertebrae, short strong ligaments, and a job description that is mostly about not moving while the hips and the ribs do. So almost nothing called a lower back stretch is really stretching the lower back. It is either moving the spine through a range it has stopped using, or it is lengthening the hips, the glutes and the hamstrings that pull on it from below.
That distinction is worth having, because it tells you what to reach for. Knees to chest and cat cow move the spine. A figure 4 or a supine twist works the hips and the deep rotators. A low lunge reaches the front of the hip, which is the part a day of sitting shortens and the part almost every back routine leaves out. A back that aches after sitting and a back that aches after standing are usually asking for different ones of those.
Direction matters more than depth
Backs are not uniform in what they like. In the research on direction-specific exercise, roughly 60 percent of people with chronic low back pain show what is called a directional preference: repeated movement one way settles the symptom, and the opposite way stirs it up. Some settle with bending forward, some with arching back, some with rotation. Nothing about the diagnosis label predicts which.
Which is why the useful skill is testing rather than pushing. Take a movement to the first honest sensation, do it a few times, and notice what happens afterwards rather than during. Easing, or symptoms drawing back toward the spine and away from the leg, means keep going. Spreading further down the leg means that is not the direction, today. Depth is not the score, and a big range achieved by gripping is worth less than a small one done cleanly.
Why the relief fades, and what goes with it
Stretching changes how much range feels acceptable, and it does that quickly. It does much less to change how much load the back can absorb on a Tuesday afternoon, which is why relief from a stretch has a habit of lasting until the next long car journey. This is not a failure of the stretch. It is the stretch doing the one job it has.
The thing that goes with it is unglamorous: some strength behind the hips and some control through the middle, added in small amounts and often. That is why the sequence below does not stop at the stretches. Two bridges sit at the end of it, and they are the reason the rest is worth doing more than once.
The sequence
- 1
Cat cow · 60 to 90 seconds, slowly
Moves the spine both ways before you ask it for range in one. First thing in the morning this is usually more useful than any single hold, because it tells you which direction the day is offering.
- 2
Knees to chest · 30 to 60 seconds
Passive bending with the floor taking all the weight, so there is no load through the spine at all. This is the position most people find on their own, and it is the right instinct.
- 3
Knees to chest, single leg · 30 to 60 seconds each side
One side at a time, which is the cheapest way to find out whether the two hips are behaving differently. That answer changes what the rest of the session should do.
- 4
Supine twist, pillow between the knees · 60 to 90 seconds each side
Rotation is the direction sitting takes first. The pillow controls how far the knees drop, which keeps the pelvis honest and lets a sensitive back have the movement at a depth it can accept.
- 5
Supine twist · 1 to 2 minutes each side
The fuller version, once the pillow one is comfortable. Same movement, more range, and a good example of adding depth after the shape is established rather than at the start.
- 6
Low lunge, short stance · 30 to 60 seconds each side
The front of the hip, which sitting shortens and which pulls on the lower back from below. The short step keeps the stretch moderate and stops the lower back arching to find range the hip should be giving.
- 7
Mini bridge · 8 to 10 slow lifts
Where the stretching stops and the other half starts. The smallest bridge in the library, built to reach the back of the hips without asking the lower back to arch.
- 8
Bridge, dynamic · 6 to 8 slow rolls
Rolling the pelvis up and down one segment at a time, driven from the hips. Mobility and strength in the same movement, and the natural next step once the mini bridge is easy.
About fifteen minutes at a comfortable pace. If a movement reproduces symptoms travelling down the leg, come out of it rather than breathing through it, and take the smaller version instead: cat cow has a small-range option, the twist has the pillow, and the lunge can be done holding a chair. Everything above except the lunge and the bridges has a seated chair version if getting to the floor is the hard part.
What the research says
Published guidance on low back pain does not name a best stretch, and that absence is deliberate. NICE guideline NG59 recommends advice and information tailored to the person, including encouragement to continue with normal activities, and then says to consider a group exercise programme, described as biomechanical, aerobic, mind-body, or a combination, taking the person's specific needs, preferences and capabilities into account when choosing the type. What it recommends is a programme chosen around a person, not a posture.
The American College of Physicians reaches a similar place from the other side of the Atlantic. Its guideline on noninvasive treatment recommends that clinicians and patients with chronic low back pain start with nonpharmacologic treatment, and the named options include exercise, motor control exercise, mindfulness-based stress reduction, tai chi and yoga. Yoga sits on the list of first-line options rather than in a footnote.
On how much any of it does, the honest numbers come from the largest review there is. The 2021 Cochrane review of exercise therapy for chronic low back pain pooled 249 trials and found moderate-certainty evidence that exercise beats no treatment, usual care or placebo for pain, by about 15 points on a 100-point scale at earliest follow-up, while the effect on functional limitations was smaller and did not reach the authors' threshold for clinical importance. Compared with other conservative treatments, exercise came out slightly ahead but below that same threshold. The World Health Organization's 2023 guideline lands on a conditional recommendation that structured exercise therapy may be offered as part of care. Read together: moving beats not moving, no single flavour of movement has been shown to beat the others, and so the question worth asking is not which stretch is best but which movements suit this back, today.

Common questions
What is the best stretch for lower back pain?
There is no single answer, and the guidelines do not offer one. NICE recommends an exercise programme chosen around the person rather than a named posture or a direction, and the American College of Physicians guideline lists several first-line options rather than one. In practice the two most reliable starting points are cat cow and knees to chest, because both are gentle enough to tell you something without committing you to anything.
Should a back that is currently sore be stretched at all?
Guidance points towards continuing normal activity and adjusting what you do, rather than stopping. Some sensation while moving is normal and is not evidence of damage. The signals to stop a particular movement are sharp pain, symptoms travelling further down the leg, or anything that leaves the area worse for the rest of the day.
How long should a lower back stretch be held?
The library holds the passive positions for 30 seconds to about three minutes, and the moving ones for around a minute. Longer is not better. A hold long enough to stop bracing against it is doing the job, and holding past the point where the position gets uncomfortable tends to reintroduce the bracing.
Why does the relief from stretching not last?
Because stretching mostly changes how much range feels acceptable, and that is a fast change and a temporary one. It does less to change how much load the back can take on an ordinary day. That is the argument for pairing it with the bridges at the end of the sequence rather than stretching alone.
Is stretching or strengthening better?
NICE does not pick between them, and the Cochrane review found only small differences between exercise types. Most backs need some of both, because the usual pattern involves muscles that are gripping and muscles that have gone quiet, and those two need opposite things.
Can these be done in a chair, or in bed?
Several can. Cat cow and the supine twist have seated chair versions in the library, and knees to chest works on any firm surface. The bridges need the floor or a firm mattress to be worth doing, because a soft surface takes the work out of them.
See a doctor promptly rather than starting a stretching routine if the pain followed a significant fall or accident, or comes with unexplained weight loss, fever, weakness in the leg or foot rather than just pain, numbness around the groin or back passage, or any change in bladder or bowel control. Stop any movement that sharply increases pain or sends symptoms further down the leg.
