Hamstring Tendonitis Stretches: A Gentle Lying Lesson

Most hamstring tendonitis stretches pull the leg long and fold the body forward, and for a sore tendon near the sitting bone that is often the very move that stings the next morning. The lesson above takes a different route. You lie on your back with your knees bent, slide one heel a short way along the floor, and notice how the pelvis and the back of the thigh answer. Nothing is pulled to its limit. The idea comes from the Feldenkrais Method®, which works with small, slow movement and close attention rather than range.

The ache this page is written for sits deep under one buttock, right where the hamstrings anchor to the sitting bone. It tends to build through a long drive or a day on a hard chair, and it often eases once you stand and walk. Clinicians call it proximal hamstring tendinopathy, or high hamstring tendinopathy. Most people search for it as hamstring tendonitis. Whatever the name, it behaves in a particular way, and that behavior shapes everything that follows.

Hamstring tendinitis or tendinopathy: what the words mean

Tendinitis is the older word. The ending, itis, means inflammation, so it pictures a hot, swollen tendon. Tendinopathy is the newer and broader word: a tendon that has become sensitive and has changed a little in its structure, usually after more load or pressure than it could adapt to at the time. Under a microscope, long standing tendon pain shows surprisingly little of the classic inflammation. That is why most clinicians now say tendinopathy, and why rest on its own rarely settles it for good.

Tendons that carry the same load day after day can become sensitive anywhere in the body. The best studied example is the Achilles: about one athlete in four is estimated to meet Achilles tendinopathy over a lifetime (StatPearls, 2024). The hamstring tendon at the sitting bone is less studied, but it seems to follow the same slow, stubborn pattern, and it has one extra complication. You sit on it.

Why hamstring tendonitis stretches so often backfire

Picture the hamstring tendon as a rope that runs over the edge of the sitting bone before it anchors there. When the hip bends and the knee straightens, the rope is drawn taut over that edge. This is exactly the shape of a classic hamstring stretch: sitting with one leg out in front, or bending forward toward the toes. The tendon is pressed against the bone at the same moment it is pulled. Clinicians call this compressive load, and a sensitive tendon tends to dislike it more than anything else.

Sitting does the same thing more quietly. A hard chair presses up, your weight presses down, and the tendon is caught between them for an hour at a time. So the two things people most often do for this ache, stretching it and sitting through it, are the two things most likely to keep it going. None of this is a failing. The urge to stretch a tight feeling is reasonable; it just does not suit this tendon.

How to practice these hamstring tendonitis stretches

Think of them as movements rather than stretches. Lie on a rug or a firm bed with your knees bent and your feet flat, so the sitting bones carry no weight at all. The heel slide is tiny: a hand's width along the floor is plenty, and less is fine. Go slowly enough to feel the knee straighten a little and the pelvis rock, and stop well before anything tugs at the back of the thigh. If a movement is not comfortable today, make it smaller, or simply picture it. In Feldenkrais® lessons, imagining a movement is a real part of the practice.

Rest between the movements. The pauses are where you compare one side with the other, and where the back of the thigh has a chance to settle. Eight to twelve minutes is enough. If the ache under the sitting bone is louder that evening or the next morning, make the movement smaller next time and see whether the tendon settles.

When to try it, and who should skip it

Good moments are the end of a desk day, after a long drive, or first thing in the morning when the back of the thigh feels stiff. It also suits the evening, since nothing here raises the heart rate.

Some situations ask for a clinician first. Pain that began with a sudden tearing or popping feeling during sport, with bruising behind the thigh, is a different injury and belongs with a doctor or physiotherapist. So does tingling, numbness, or weakness running down the leg, which points toward a nerve rather than a tendon. A leg that feels unsteady or gives way, or pain that followed a fall, deserve the same care. After hip or back surgery, stay inside whatever limits your surgeon has set, and ask before adding this. During pregnancy, if lying flat makes you light headed, rest on your side and imagine the movements instead.

Easing the positions that press on the tendon

Movement helps most when the tendon is not being pressed for the rest of the day. A softer seat, or a cushion with the sore side cut away, spreads the pressure. Standing up for phone calls and breaking a long drive with a short walk changes the dose. Tilting the base of the car seat back a little shifts weight toward the thighs. Deep forward folds, stretching straps, and hard hill running are worth pausing while the tendon is sensitive. Our guide to hamstring pain while sitting goes into the chair and car details.

Where graded loading and clinical care fit

The mainstay of care for a sensitive tendon is graded loading: asking the tendon to work, then slowly asking a little more over weeks and months. It usually begins with isometrics, where the muscle works against something without moving, and builds from there under a physiotherapist who knows your tendon. This page does not set out that program, because the dose depends on your tendon and your history. The lying lesson sits alongside that plan. It keeps the back of the thigh on easy terms with movement, and it helps you feel the difference between a tendon being worked and a tendon being pressed.

Yoga and Pilates work through a different mechanism, and each has its own strengths. While the tendon is sensitive, deep forward folds in either may bother it, so it is worth telling your teacher. The Feldenkrais® approach is quieter still. It asks how the pelvis and leg organize themselves, and it lets the tendon rest while you learn.

If you are coming back after a strain rather than a slow building ache, our hamstring recovery exercises are a closer fit, and the lying lesson in our stretches for an injured hamstring shares the same small, slow spirit. Our Feldypedia entry on movement recovery after surgery and injury explains why a guarded body part often needs attention before it needs effort. The Feldy program for recovering from injury or surgery carries this approach across many short lessons, and you can try Feldy free for 7 days, no credit card needed.

Find where to start

A sore tendon at the sitting bone is one story, and the back of the thigh can ache for several other reasons. Which movement method suits you depends as much on how you like to move as on where it hurts.

Common Questions about hamstring tendonitis stretches (FAQ)

What is the best hamstring tendonitis stretch when sitting is what hurts?

For an ache that builds under the sitting bone, the kindest option is barely a stretch at all: the small heel slide from the lesson, lying on your back with the knee bent. It lets the back of the thigh lengthen a little while the tendon is neither pressed against the bone nor pulled to its limit. Any stretch that folds you forward over a straight leg does the opposite, so it can wait until the tendon is calmer and a clinician agrees.

Which movements are worth leaving out while the tendon is sore?

Deep forward folds, seated toe touches, stretching straps, and long holds with a straight leg all press the tendon against the sitting bone. Long spells on a hard chair or a bike saddle do the same more slowly. Fast hill running and sprinting ask a lot of the tendon before it is ready. Leaving these out for a while simply changes the conditions the tendon lives under.

Is it safe to try these when the ache runs down the back of my thigh?

A dull ache that stays at the sitting bone and the upper thigh is the usual pattern for a sensitive tendon, and the small movements here are generally comfortable for it. Pain that travels past the knee, or that brings tingling, numbness, or weakness, points toward a nerve, and that needs a clinician before you add anything new. If a movement leaves the ache sharper that day or the next, make it smaller or leave it out.

How often is sensible with a sore hamstring tendon?

A short session most days suits this lesson, because you are practicing attention rather than loading tissue, so there is nothing to recover from. Tendons do respond to the total they are asked to do in a day, so the lesson, your loading plan, the sitting, and the walking all add up. If the sitting bone is more tender the next morning, that is useful information about the whole day, not a reason to push harder.

How many weeks before a hamstring tendon feels calmer?

Tendons are slow, and this one is slower than most because you sit on it. Many people describe steady change over two to three months of patient work rather than weeks, with better days and worse days along the way. The lying lesson can feel pleasant the same day, but treat that ease as information, not as a sign that the tendon is ready for a deep stretch.

How is this different from the isometrics and loading my physio gave me?

Your loading plan asks the tendon to work, and then slowly to work harder, which is what helps a tendon rebuild its capacity over time. This lesson asks almost nothing of the tendon. It works on how you sense and organize the pelvis and leg, so the loading you do is easier to feel and easier to steer. The two sit alongside each other, and the physiotherapist's plan leads.

Which signs mean I should stop experimenting and have the leg looked at?

A sudden tearing or popping feeling during sport, especially with bruising behind the thigh. Tingling, numbness, or weakness anywhere down the leg. A leg that feels as if it might give way, pain that followed a fall, or an ache that keeps building over several weeks despite gentler sitting and less stretching. Any of these is a reason to see a doctor or physiotherapist rather than to keep trying things on your own.
