Runner's Stretch
The runner's stretch is a standing hamstring stretch where you extend one leg forward and hinge at the hips to lengthen the back of your leg. It targets the hamstrings directly, with the calves getting a secondary stretch through the ankle position. It's a quick, no-equipment option for loosening tight hamstrings before or after a run.
Why it works
Extending one leg forward with a straight or nearly straight knee, then hinging forward at the hips, pulls the hamstring through its full length from the sit bone to just below the knee. Keeping the ankle flexed, toes pulled toward you, adds tension through the calf as well, since the calf crosses behind the ankle joint.
Set up
- Stand tall and step one foot forward, heel on the ground and toes pointed up.
- Keep a slight bend in your standing leg's knee for balance.
- Rest your hands on your front thigh or hips to support your posture.
How to do it
- Keep your front knee straight or nearly straight, heel down and toes lifted.
- Hinge forward from your hips, keeping your back flat rather than rounding.
- Lower until you feel a firm stretch along the back of your front leg.
- Hold the position, then return to standing and switch legs.
Form cues
- Hinge from the hips, not by rounding your lower back.
- Keep your front toes pulled up toward your shin.
- Keep a soft bend in your back knee for stability.
- Stop lowering the moment you feel a stretch rather than pain.
Breathing: Breathe slowly and evenly while you hold the stretch, letting each exhale ease you slightly deeper.
Common mistakes
Rounding the lower back to reach further.
Fix: Keep your spine flat and hinge from the hips instead, even if that means a smaller range of motion.
Locking the front knee too hard.
Fix: Keep a very slight softness in the knee rather than pressing it back to full lockout.
Bouncing to deepen the stretch.
Fix: Hold the position still rather than bouncing, which can trigger a protective muscle contraction instead of a release.
How to program it
- This is a gentle static stretch, so it works well daily, especially after runs or leg training.
- Hold each side for 20 to 30 seconds, for 2 to 3 rounds per leg.
- Save deep static holds for after activity rather than right before a run, when a light dynamic warm-up serves you better.
Safety notes
- Stop at the point of a firm stretch. Sharp pain or numbness means you've gone too far.
- Skip deep holds directly before sprinting or explosive work, since a very loose hamstring right before max-effort running can affect performance.

Frequently asked questions
How long should I hold the runner's stretch?
20 to 30 seconds per leg, for 2 to 3 rounds, is enough to loosen tight hamstrings.
Should I do this stretch before or after running?
It's best saved for after your run or as part of a separate flexibility session. A light dynamic warm-up works better right before running.
What can I do if I can't reach my hamstrings comfortably?
A seated hamstring stretch on the floor lets you support your back against the ground while you work on the same flexibility.
Why do I feel this stretch in my lower back instead of my hamstrings?
You're likely rounding your spine to reach further instead of hinging from your hips. Keep your back flat and stop lowering once your hips can't hinge any further without rounding.
