Lying Sartorius Stretch
Lying Sartorius Stretch Exercise Description
The lying sartorius stretch targets the sartorius, a long biarticular muscle that flexes, abducts, and externally rotates the hip and flexes the knee. To lengthen it, place the hip in extension, adduction, and slight internal rotation while keeping the knee extended. Performing this supine helps control pelvic position and reduce compensations from the lumbar spine. You’ll bias the sartorius relative to the rectus femoris and tensor fasciae latae by moving the thigh slightly behind the body, across the midline, and turning the thigh inward with a straight knee. Expect a gentle stretch through the front/inner thigh or near the medial knee; ease off if you feel pinching or joint pain.

How To Do The Lying Sartorius Stretch Exercise
‘- Lie on your back near the edge of a firm surface. Bend the non-stretching leg, foot flat, to stabilize your pelvis.
– Set your trunk: ribs down, pelvis level, and maintain a neutral spine (avoid arching).
– Straighten the stretching leg and let the thigh slide so it’s just off the edge, creating slight hip extension. Keep the knee fully straight.
– Adduct: move the straight leg a few centimeters toward/over the midline.
– Internally rotate the thigh: point the toes slightly inward so the kneecap faces more toward the midline.
– Lightly brace your abdominal wall and keep both hip bones facing up; avoid tilting or rotating the pelvis.
– Breathe slowly. Seek a gentle, diffuse stretch—no sharp pain or numbness.
– To exit, return the leg to the surface before rolling or sitting up.
– Common fixes: if you feel low-back pressure, reduce how far the thigh extends and re-establish neutral spine; if the stretch fades, confirm the knee stays straight and the toes remain slightly inward.
Lying Sartorius Stretch Tips
‘- Bend the non-stretching leg with the foot flat on the surface to help stabilize your pelvis.
– Keep ribs down, pelvis level, and maintain a neutral spine; avoid letting your low back arch.
– Slide the stretching thigh just off the edge to create slight hip extension while keeping the knee fully straight.
– Move the straight leg a few centimeters toward or across the midline to add hip adduction.
– Point the toes slightly inward so the kneecap faces more toward the midline to create internal rotation.
– Lightly brace your abdominal wall and keep both hip bones facing straight up to avoid pelvic tilting or rotation.
– Breathe slowly throughout the stretch.
– Look for a gentle, diffuse stretch at the front/inner thigh or near the medial knee; avoid sharp pain, pinching, numbness, or joint pain.
– When finishing, bring the leg fully back onto the surface before you roll or sit up.
– If you feel low-back pressure, reduce how far the thigh extends and re-establish your neutral spine.
– If the stretch fades, check that the knee is still straight and the toes remain slightly turned inward.
Lying Sartorius Stretch Beginner Introduction
The lying sartorius stretch is a floor-based flexibility drill performed on a firm surface while lying on the back. It emphasizes a long hip flexor that runs from the outer hip area down toward the inner knee. This muscle is lengthened by positioning the thigh slightly behind the body, angled a bit inward, with the knee straight. Being on the back allows the pelvis and lower spine to stay more stable, so the stretch targets the front and inner thigh instead of the low back.
During this stretch, one leg rests bent on the surface for support while the other leg extends, with the thigh drifting just past the edge and slightly across the body. A mild inward turn of the leg increases the sense of length along the front of the thigh or near the inner side of the knee. Calm, steady breathing and a quiet trunk encourage a smooth, broad stretching sensation. The goal sensation is gentle tension rather than sharp discomfort, with any feeling of pinching or joint pain indicating that the position typically needs modification.
