Yoga for a hamstring injury: when to start, strength before stretch, which poses to change, getting back to sport, what the evidence shows, and a class

No yoga trial

Our searches found no trial of yoga after a hamstring strain or tear. Yoga can be part of getting back to normal, but the evidence is for early, graded loading and a return-to-sport plan, and yoga replaces neither.

Two kinds of strain, and yoga can cause the slow one

Sprinting strains hurt at once but heal faster. Stretching strains happen in slow, deep hip bends with the knee straight, the shape of a deep forward fold or the splits; they feel milder, sit near the sitting bone, and took about a year to recover in professional dancers.

Sources 2, 3, 4

Start within days, gently

The NHS advises rest, ice, compression and raising the leg for the first 2 to 3 days, then keeping it moving once pain allows. Starting rehab 2 days after a thigh or calf strain rather than 9 got people back to sport about 3 weeks sooner, with a similar re-injury rate.

Sources 5, 6

Strength and controlled lengthening before stretch

Lengthening exercises done under control got elite footballers back in 28 days rather than 51, and sprinters and jumpers in 49 rather than 86. Starting them on day 1 rather than later added nothing.

Sources 7, 8, 9, 10

Deep folds come back last

No trial compares stretching with not stretching after a strain; stretching 4 times a day rather than once saved under 2 days in the only dose trial. Stretch to a mild pull, and leave deep folds, pyramid, triangle and the splits until you can sprint without pain.

Sources 11, 12, 3

Getting back to sport is its own plan

Pain-free sprinting, strength and field tests decide it, not flexibility. Re-injuries come early and in the same place, over half within 4 weeks of going back, so yoga sits beside the running and Nordic curl work, not instead of it.

Sources 13, 14, 15, 16

A sudden pain at the back of the thighStrong evidence

A hamstring injury is a strain or tear in the muscles or tendons at the back of the thigh, usually while sprinting or stretching hard. The NHS lists sudden pain, sometimes a snapping or popping feeling, then tenderness, swelling and bruising, and trouble standing or walking. It says "Mild hamstring injuries usually get better in a few days" and "Severe hamstring injuries can take weeks or months to heal".

Sources 5, 17

Common, and it comes backStrong evidence

In men's professional football, hamstring injuries rose from 12% to 24% of all injuries over 21 seasons, with a median of 13 days out; across field sports they are about 10% of injuries (a review with a published correction we couldn't read). 18% of footballers' hamstring injuries were repeats, and a previous injury is the biggest risk factor for the next, with older age.

Sources 16, 18, 19, 20

Two kinds of strainEmerging evidence

In elite sprinters, strains during sprinting took a median of 16 weeks to return to their old level. In professional dancers, strains came "during slow hip-flexion movements with extended knee", sat near the sitting bone, felt mild at first, and took a median of 50 weeks. Sprinters start with more loss of function but recover more quickly.

Sources 2, 3, 4

Grades and timeEmerging evidence

Specialists grade strains on magnetic resonance imaging (MRI) scans, often with the British Athletics system. In 255 hamstring injuries in professional football, grade 1 strains took about 18 days and grade 2 about 24 days. Strains that run into the tendon took longer, about 5 to 7 weeks in elite athletes, whatever the rehab. Healing on MRI was still under way when people went back.

Sources 21, 22, 23, 8, 24

When the tendon comes off the boneEmerging evidence

In the most severe injuries, the tendon tears away from the bone near the sitting bone. This is often missed, and surgeons prefer to repair it early: in one review, repairs done within about 4 weeks returned people to sport sooner. It isn't only a young athlete's injury: the average age at repair was 44.7. In teenagers, the tendon can pull off a piece of bone.

Sources 17, 25, 26, 27, 28

How yoga loads the hamstrings

Forward folds, pyramid, triangle, hand-to-big-toe poses, downward dog with straight legs and the splits stretch the hamstrings, most at the sitting bone end when the knee is straight and the hip deeply bent. Bridges, chair pose, locust and warrior III ask them to work, mostly without much lengthening. So a class can keep you moving while a hamstring heals, if the long-stretch poses are changed. No study has measured these poses after a strain; this is our reading.

The first 3 daysStrong evidence

The NHS advises rest, ice, compression and raising the leg (PRICE) for the first 2 to 3 days, and to avoid heat, massage and alcohol for the first 3 days. "When you can move your leg without pain stopping you, try to keep moving it so your hamstring does not become stiff."

Source 5

An early start beats waitingEmerging evidence

In 50 recreational athletes with a severe thigh or calf strain, starting rehab 2 days after the injury rather than 9 returned them to sport after 63 days rather than 83, with a similar re-injury rate at a year. That programme began with gentle stretching and holds; not every strain in it was a hamstring.

Sources 6, 29

Some discomfort is fineEmerging evidence

In 43 men, rehab that allowed pain up to a tolerable level returned players as fast as strictly pain-free rehab and kept more strength. Experts advise avoiding high strain early, and pain-free sprinting before going back. The pain rule is in the warning signs below.

Sources 30, 14

Our suggested timeline

Breathing, upper body and chair yoga from day 1. Gentle hamstring work (bridge holds, heel slides, pain-free range) from about day 2 or 3, once walking is comfortable. No hot yoga and no hamstring stretching in the first 3 days. Standing poses as walking gets easy. This is our suggestion, from the NHS advice and the early-start trial, and it follows the stages of our hamstring strain guide.

No yoga trialStrong evidence

Our searches of PubMed and Europe PMC found no trial of yoga after a hamstring strain, tear or tendon injury.

Lengthening exercises got athletes back weeks soonerEmerging evidence

In two trials from one Swedish group, a programme built on three lengthening exercises (the Extender, the Diver and the Glider) returned elite footballers to training in 28 days rather than 51, and elite sprinters and jumpers in 49 days rather than 86, against conventional exercises. Pooled, the rate of getting back was about 3 times higher, with no difference in re-injury. Neither trial could be blinded.

The exercise details here come from a later trial's description of the programme (Vermeulen 2022), in which the exercises started from 5 days after the injury; we read only summaries of the original trials.

Sources 7, 8, 9, 10

Starting them on day 1 added nothingEmerging evidence

In 90 male athletes, starting the lengthening exercises on day 1 rather than once they could run at 70% of top speed didn't shorten the return to sport or change re-injury. Range was built up only until pain or discomfort began. Rushing them doesn't help.

Source 10

Agility and trunk controlMixed evidence

In 24 athletes, 1 of 13 who did agility and trunk control work was re-injured within a year, against 7 of 10 who did stretching and strengthening. A later trial of 31 people didn't repeat the difference. A 2023 review of 9 trials concluded the programme can prevent re-injury. Yoga's planks and balances overlap with this trunk work (our reading).

Sources 31, 24, 32, 11

Stretching: when and how hardMixed evidence

The only trial of stretching dose: in 80 athletes, stretching 4 times a day rather than once shortened the return from about 15 days to 13. A Cochrane review, searched to 2012, calls this limited evidence, and says most rehab methods haven't been tested in trials. No trial compares stretching with no stretching. Strains that come from slow, deep stretching were the slowest to heal, which is why our suggestion is a mild pull only, with deep folds back last.

Sources 12, 11, 32, 3

InjectionsStrong evidence

Platelet-rich plasma (PRP) injections didn't speed the return to play or reduce re-injuries at a year in 80 athletes, and a review of 3 trials agrees.

Sources 33, 9

Downward dog and sun salutations

Bend your knees well, and step forward and back rather than jumping, until sprinting is pain-free.

Seated folds, when they return

Head-to-knee pose's own page: "Sit on a folded blanket and keep a small bend in the straight knee if your pelvis tips backwards." Do the same in other seated folds.

Hot yoga

Not in the first 3 days (our suggestion: the NHS advises avoiding heat, such as hot baths and heat packs, then).

Source 5

Hands-on adjustments

Say no to anyone pressing your back down in a fold. You can say no to any hands-on adjustment, and a teacher registered with Yoga Alliance must get your explicit consent each time.

A deep ache at the sitting bone that built up over weeks

That isn't a strain. Our yoga for hamstrings guide and our high hamstring tendinopathy guide cover it.

What decides itEmerging evidence

In a worldwide consensus of 58 experts, return to play needed medical clearance, no pain when the muscle is pressed, no pain in strength and flexibility tests or in or after functional tests, flexibility similar to the other side, field test performance and feeling ready. A later consensus made pain-free sprinting its one firm rule, and the experts couldn't agree on a flexibility benchmark.

Sources 13, 14

Re-injuries come earlyEmerging evidence

In 19 re-injuries confirmed on MRI, 79% were in the same place and more than half came within 4 weeks of going back. In professional football, 69% of repeat injuries came within 2 months, and repeat rates in studies range from about 14% to 63%.

Sources 15, 16, 19

The Nordic curl and warm-up programmesMixed evidence

Programmes that include the Nordic curl were linked with about half as many hamstring injuries across 15 studies, and two large football trials found big falls. But when only properly randomised trials are pooled the effect is uncertain, and a 2026 network analysis of 11 trials in football found the FIFA 11+ warm-up reduced hamstring injuries while the Nordic curl on its own didn't clearly do so, at low to very low certainty. Worth doing as part of a plan, not a guarantee.

Sources 34, 35, 36, 37, 38

Stretching doesn't prevent strainsStrong evidence

Flexibility training didn't reduce hamstring strains in elite football, and across 25 trials stretching didn't prevent sports injuries while strength training did. In larger studies, tight hamstrings were at most a weak risk factor.

A pop high on the back of the thigh

Same day: a pop near the sitting bone, a large bruise high on the back of the thigh, or you cannot put weight on the leg. The tendon may have pulled away from the bone, which needs assessing before you start these exercises.

Same day (NHS 111 or your GP): you felt a pop or tearing high on the back of your thigh, near the sitting bone, and it's very painful, there's a lot of swelling or bruising (which can spread down the thigh over the next few days), it hurts to walk or stand, or sitting is painful. The tendon may have come away from the bone. Ask for a scan within days. That timing is our suggestion: no source gives a fixed deadline, but this injury is easily missed, and a specialist needs to see it while every option is still open.

Sources 5, 25

A lump or a dent

A bunched-up lump of muscle, or a dent you can feel, high on the back of the thigh after a pop: get it checked the same day (our suggestion, from a US orthopaedic surgeons' patient page and an expert consensus on when to operate).

Sources 17, 28

Teenagers

Same day, for an X-ray (our suggestion): a teenager with sudden pain at the sitting bone after a sprint, a kick or the splits, often with a pop, especially if walking or sitting hurts. While the bones are still growing, the tendon can pull off a piece of bone.

After a fall

Call 999 or go to A&E: severe pain after a fall onto your hip or bottom, or you cannot walk or put weight on the leg.

Low on the thigh, near the knee

A pop or sudden sharp pain low at the back of the thigh or at the back corner of the knee during a curl or a sprint, then bruising, a gap you can feel just above the bony bump on the outside of the knee, or weakness bending the knee: get it checked within a few days through your GP, a physiotherapist or NHS 111. Most hamstring problems near the knee settle without surgery, but a tendon pulled off the bone often needs repair (our suggestion).

NHS 111

Get help from NHS 111 if you think you've injured your hamstring and it's very painful, or the pain is getting worse; there's a large amount of swelling or bruising, or the swelling or bruising is getting worse; it hurts to walk or stand using the injured leg; your leg feels very stiff or is difficult to move; it's not feeling any better after treating it yourself; or you have a very high temperature or you feel very hot, but also cold and shivery, which could be signs of an infection.

A swollen, painful leg

Same day (urgent GP appointment or NHS 111): after a bad hamstring tear, the leg becomes more swollen, throbbing or discoloured. A clot can feel like a pulled hamstring, and clots are more likely after a complete tear of the tendon.

Same day (urgent GP appointment or NHS 111): throbbing pain in one leg (rarely both), usually the calf or thigh; swelling in one leg (rarely both); red, blue or darkened skin around the painful area, which may be harder to see on brown or black skin; or swollen veins. This can be a deep vein thrombosis (DVT). It is more likely after surgery, a hospital stay, 3 or more days in bed, a journey of over 4 hours, pregnancy or a recent birth, cancer, a previous clot, or contraception or hormone replacement therapy (HRT) that contains oestrogen.

Call 999 or go to A&E if breathing suddenly becomes difficult, if pain in your chest or upper back comes on suddenly with breathlessness or a very fast heartbeat, or if someone passes out. Do not drive yourself. It can be a blood clot that has reached the lungs.

See a physiotherapist or GP

• Your hamstring injury is taking longer to heal than expected, or you've had hamstring injuries before: see a physiotherapist. NHS physiotherapy is free, though there may be a wait.
• A second strain in the same place: ask a physiotherapist to review your rehab.
• Pain in the back of the thigh with tingling, numbness, or pain spreading below the knee: it may come from the back (sciatica).
• Deep pain low in the buttock with sitting and running that is not settling: possible high hamstring tendinopathy, which has its own guide.

The pain rule

Mild to moderate discomfort that you find tolerable is fine during exercise; in a trial, working that way did no harm and recovered more strength. In the lengthening exercises (the Extender and the Diver), stop just before pain. Sharp pain, or a limp afterwards, means back off for a session or two.

In stretches, a mild pull only, never to the end of your range, until sprinting is pain-free (our suggestion).

Very flexible joints

If you're hypermobile, don't use mobility work to push further: the NHS says "do not overextend your joints just because you can". See a GP if you think you have joint hypermobility syndrome: for example, your joints keep dislocating, or you keep getting sprains, strains, pain or stiffness.

Source 44

Chest pain or fainting: call 999

Call 999 if:

• You get sudden pain or discomfort in your chest that doesn't go away; it can feel like squeezing or pressure, burning or indigestion.
• The pain spreads to your left or right arm, or your neck, jaw, stomach or back.
• You have chest pain and feel sweaty, sick, light-headed or short of breath.
• Someone faints while exercising, can't be woken within 1 minute, or has chest pain or a pounding, fluttering or irregular heartbeat.

Sources 45, 46

Unusual breathlessness

Call 999 or go to A&E (accident and emergency) straight away for severe difficulty breathing (gasping, choking or not able to get words out), a chest that feels tight or heavy, pain that spreads to your arms, back, neck and jaw, lips or skin turning very pale, blue or grey, or sudden confusion. If you're more short of breath than usual, or your heart is racing, fluttering or skipping beats, contact NHS 111.

During yoga

A joint pain that is sharp, gets worse during a session, lingers into the next day or changes how you move is a reason to use an easier version, and to see a GP or physiotherapist if it keeps happening (the rule in our plans). Muscle soreness for a day or two after something new is normal. In a hot class, stop if you feel dizzy, sick or unwell; our hot yoga guide lists the signs of heat illness.

Before you start

The NHS advises getting advice from a healthcare professional first if you have a health problem, an injury or symptoms, or have recently had a heart attack or an operation.

"Stretch a pulled hamstring as soon as you can"Emerging evidence

No trial compares stretching with not stretching, and more frequent stretching saved under 2 days in the only dose trial. Strains caused by deep stretching took the longest to heal. What shortened the return was an early start and controlled lengthening under load. Gentle range, yes; deep folds, later.

Sources 12, 11, 3, 9, 6

"Rest it completely until it stops hurting"Emerging evidence

Starting rehab on day 2 rather than day 9 got people back about 3 weeks sooner with similar re-injury, and the NHS says keep moving once pain allows.

"Stretching before sport prevents hamstring injuries"Strong evidence

Flexibility training made no difference to hamstring strains in elite football, and across 25 trials stretching didn't prevent sports injuries, while strength training did.

Sources 39, 40

"Tight hamstrings cause strains, so the more flexible the better"Emerging evidence

One study found injured players had been less flexible, but larger ones found no link, or a difference of under 2 degrees with little clinical value. Age and a previous injury matter more, and the slowest strains happen at the end of a big range. With very flexible joints, the NHS says "do not overextend your joints just because you can".

Sources 48, 41, 42, 20, 3, 44

"Once it stops hurting, you're ready for sport"Emerging evidence

Healing was still visible on MRI at return, re-injuries cluster in the first 4 weeks back, and experts want pain-free strength, flexibility and field tests, and pain-free sprinting, first.

Programmes with them were linked with half as many injuries in one review, but the randomised evidence is uncertain. Worth doing, not a guarantee.

"A hamstring tear always heals with rest"Emerging evidence

Most strains do, but a tendon pulled off the bone is often missed and is usually repaired early, within weeks.

"Yoga is a proven treatment for a pulled hamstring"Strong evidence

No trial has tested it. It can carry some of the strength, balance and gentle range work, beside a rehab plan.
