Leg Up Hamstring Stretch
Leg Up Hamstring Stretch Exercise Description
The Leg Up Hamstring Stretch (supine straight‑leg hamstring stretch) targets the posterior thigh, emphasizing the hamstrings: semitendinosus, semimembranosus, and the long head of biceps femoris. Performed lying on your back, it uses hip flexion with a mostly extended knee to lengthen the hamstrings while the pelvis and lumbar spine remain neutral against the floor. Keeping the sacrum “heavy” and the lifted leg aligned with the same‑side hip helps you feel the stretch in the muscle belly rather than at the knee or low back. A strap or towel around the mid‑foot lets you maintain alignment without reaching or rounding the shoulders. This controlled, alignment‑focused approach works well for both beginners learning foundational flexibility and experienced exercisers maintaining posterior chain range of motion. Subtle ankle dorsiflexion can increase tension on the gastrocnemius if you want to include the calf, but keep the knee straight to emphasize the hamstrings. Aim for a gentle, even stretch along the back of the thigh—stop short of pinching or nerve‑like sensations.

How To Do The Leg Up Hamstring Stretch Exercise
‘- Lie on your back with your head, rib cage, and sacrum resting on the floor.
– Extend one leg along the floor; keep it straight or slightly bent if needed to maintain a neutral spine.
– Lift the other leg by flexing at the hip; keep the knee straight but not locked and the toes pointing toward the ceiling.
– Hold behind the back of the thigh or calf (not behind the knee); draw the leg toward you without shrugging the shoulders.
– Keep both hips level and the sacrum heavy; avoid letting the pelvis tuck or rotate as the leg comes up.
– Align the lifted leg with the same‑side hip—do not let it drift inward or outward.
– Breathe steadily; soften the front of the hip and let the back of the thigh lengthen.
– Option: loop a strap or towel around the mid‑foot to assist, keeping elbows close and shoulders relaxed.
– Lower the leg with control and repeat on the other side.
Leg Up Hamstring Stretch Tips
‘- Keep your head, rib cage, and sacrum resting on the floor to maintain a neutral spine.
– Extend the down leg straight or only slightly bent so you can keep your spine neutral.
– Lift the working leg from the hip with the knee straight but not locked and toes pointing toward the ceiling.
– Hold behind the back of the thigh or calf—not behind the knee—when drawing the leg toward you.
– Keep both hips level and your sacrum feeling “heavy” on the floor to avoid tucking or rotating the pelvis.
– Align the lifted leg directly with the same‑side hip so it doesn’t drift inward or outward.
– Draw the leg toward you without shrugging; keep the shoulders relaxed as you stretch.
– Breathe steadily and consciously soften the front of the hip as you let the back of the thigh lengthen.
– If using a strap or towel, loop it around the mid‑foot and keep the elbows close to your sides so the shoulders stay relaxed.
Leg Up Hamstring Stretch Beginner Introduction
The Leg Up Hamstring Stretch (supine straight‑leg hamstring stretch) is a floor-based flexibility move centered on the back of the thigh. Performed while lying on the back with one leg extended on the ground and the other raised, it uses movement from the hip with a mostly straight knee to lengthen the hamstrings. The lower back and pelvis stay settled against the floor so the stretch is felt through the middle of the thigh rather than in the knee or low back. Many people notice a smooth, gentle pull along the back of the lifted leg when the thigh, knee, and foot stay lined up with the same-side hip.
A strap or towel placed around the middle of the foot can support the raised leg without reaching or tensing the shoulders, which encourages a calmer upper body and steady breathing. This simple, alignment‑driven stretch suits beginners building basic flexibility as well as experienced movers interested in preserving ease of motion in the backs of the legs. A small ankle bend toward the shin can add a bit more sensation in the calves while the main emphasis remains on the hamstrings.
