Hamstring Stretch
This stretch targets the muscles along the back of your thighs, which tend to tighten from long hours of sitting and can pull on your lower back when they're too short. Keeping your hamstrings flexible makes it easier to bend forward safely, climb stairs, and get up from low seats. It's a gentle, low-risk movement that pays dividends in everyday comfort.

Form cues
- 01
Lie flat on your back on a firm surface — a yoga mat or carpet works well.
- 02
Bend both knees with feet flat on the floor to start, then slowly lift one leg toward the ceiling.
- 03
Hold the back of your raised thigh with both hands, or loop a belt or towel around the sole of your foot.
- 04
Straighten your raised leg as much as feels comfortable — a mild pulling sensation behind the thigh is the goal, not sharp pain.
- 05
Keep your lower back pressed gently into the floor throughout the stretch; don't let it arch up.
- 06
Keep the leg still on the floor flat and relaxed, not bent or lifted.
- 07
Breathe slowly and steadily — exhale as you ease deeper into the stretch.
- 08
Hold for 20 to 30 seconds, then switch legs.

Common mistakes
Forcing the leg too straight too fast — if your lower back lifts off the floor, you've gone too far; ease the leg back until your back settles down.
Holding your breath — you'll notice your shoulders creeping up toward your ears; consciously drop them and exhale.
Letting the resting leg bend or lift off the floor — check that your heel stays flat on the ground throughout.
Pulling with jerky, bouncing movements instead of a steady hold — bouncing can strain the muscle rather than lengthen it.
Gripping too high on the leg (behind the knee) and putting pressure on the joint — move your hands to the back of the thigh or use a belt around the foot instead.
Scale it
Easier and harder variations
Easier
Keep a generous bend in the raised knee so the stretch is mild, and use a belt or towel around your foot so you don't have to reach as far.
Use this if you feel tightness or discomfort before your leg is anywhere near vertical.
Harder
Slowly flex your foot — pull your toes toward your shin — while holding the stretch to add a gentle calf component and deepen the hamstring pull.
Try this once you can comfortably hold the basic stretch for 30 seconds with your leg fairly straight.
Note
Sit upright in a sturdy chair, extend one leg straight in front of you with your heel on the floor, and gently hinge forward from the hips — keeping your back straight — until you feel a mild stretch behind the thigh.
Use the seated version if getting down to the floor and back up is difficult, or if you have a hip or knee replacement and your surgeon has advised avoiding deep hip flexion while lying down.
