Hamstring Stretch

Overview

The hamstring stretch eases tightness at the back of the thigh, which is common with sitting, running and long periods of desk work. A comfortable seated version is easy to do daily and keeps the back of the leg feeling free.

Stretch Name

Hamstring Stretch

Primary Purpose

• Ease tightness in the hamstring muscles
• Support comfortable hip and knee movement
• Complement strength work for the back of the leg

Target Muscles

• The hamstring muscles at the back of the thigh, which attach around the knee

Difficulty Level

Beginner

Step-by-Step Instructions

1. Sit on the floor or a mat with one leg extended and the other foot flat on the floor.
2. Sit tall and hinge forward from the hips, keeping the extended leg straight.
3. Stop when you feel a mild pull at the back of the thigh.
4. Hold for 20–30 seconds, breathing normally.
5. Repeat 2–3 times, then switch legs.
6. For a gentler version, loop a towel around the foot and pull gently while lying on your back.

What You Should Feel

A mild pull at the back of the thigh. Stop if you feel sharp pain, numbness, tingling or pain radiating down the leg — those are not a normal stretch sensation.

Common Mistakes

• Rounding the back instead of hinging from the hips
• Bouncing into the stretch
• Holding the breath
• Pulling so hard behind the knee that it pinches or tingles

Easier Alternatives

• Sit on a folded blanket or cushion to tilt the hips
• Use a towel around the foot while lying on your back
• Bend the knee slightly and straighten as tolerated

Progressions

• Hold longer (up to 45 seconds)
• Add a gentle ankle pull toward you at the end of the stretch
• Pair with progressive hamstring strengthening, especially for tendon-related pain

Who Should Avoid This

Do not stretch through a recent hamstring tear without clearance. If pain radiates down the leg with numbness or weakness, arrange an assessment rather than stretching through it.
