Why it helps
Tight hamstrings can limit how far you bend forward and add strain on the lower back and knee. Lying down keeps the back supported and lets you relax into the stretch.
The strap lets you control the stretch without straining to reach your foot. If the stretch causes nerve-type symptoms, a sciatic nerve glide is often a better choice. It fits well in low back pain routines.
Step-by-Step Instructions
- Lie on your back on a mat or bed with both legs straight, or one knee bent with the foot flat.
- Loop a strap, belt or towel around the ball of one foot and hold an end in each hand.
- Keeping the knee straight, use the strap to slowly raise the leg until you feel a gentle stretch at the back of the thigh.
- Hold for 30 seconds while breathing slowly. Keep your head and lower back on the floor.
- Lower the leg slowly. Repeat 3 times, then switch legs.

Key Form Cues
- Gentle stretch: Aim for a mild pull, not pain.
- Knee straight: A soft knee is fine; do not let it bend a lot.
- Shoulders relaxed: Let the strap do the work, not your neck.
How much to do
Hold each stretch for 30 seconds, 3 times on each leg, once or twice a day.
Progression & Regression
Regression (Make It Easier)
- Keep the other knee bent with the foot flat
- Lift the leg only a little
- Try the seated back-of-leg stretch instead
Progression (Make It Harder)
- Hold for 45 to 60 seconds
- Gently draw the toes toward you at the end of the stretch
- Add a few slow knee bends and straightens while holding the strap
Who it suits, and who should check first
Good fit for: tight hamstrings, low back pain, knee stiffness and anyone who wants better flexibility for bending.
Check with your clinician first if: you have pain, tingling or numbness that travels down the leg, a recent hamstring strain, or recent hip, knee or back surgery.
Precautions
Stretch the muscle, not the nerve.
- If you feel tingling, burning or pain spreading below the knee, ease off; this suggests nerve tension rather than a muscle stretch.
- Do not bounce or pull hard on the strap.
- After a recent hamstring strain, build up gently; see our hamstring strain guide.
- Stop and consult your provider if: you feel numbness, tingling or pain shooting down the leg, sharp pain at the back of the thigh, or new weakness in the leg.
Frequently asked questions
How long should I hold a hamstring stretch?
About 30 seconds, repeated 3 times, is a common recommendation. Longer holds are fine if they stay comfortable.
Why do I feel the stretch behind my knee or in my calf?
That can be normal tightness, but tingling or burning suggests the sciatic nerve is being stretched. Bend the knee slightly and ease off.
Is this stretch good for low back pain?
It can help when tight hamstrings limit bending. It is usually part of a wider program that includes strength work.
