Half Kneeling Hamstrings Stretch
- Beginner
- Isolation
- Timed hold
- Lower legs
This unilateral stretch isolates the hamstrings to improve flexibility and hip mobility while reducing lower back tension. By kneeling on one leg, you stabilize the pelvis to ensure the stretch is felt deeply throughout the entire length of the target hamstring.

Setup
- Begin in a half-kneeling position with your right knee on the floor and your left foot flat in front of you.
- Straighten your left leg forward, resting your heel on the ground with your toes pointed toward the ceiling.
- Place your hands on your hips or on the floor on either side of your front leg for balance.
- Ensure your hips are square to the front and your torso is tall and upright.
How to do it
- Inhale deeply and lengthen your spine, pulling your shoulders back and down.
- Exhale as you slowly hinge forward from the hips, leading with your chest toward your front knee.
- Maintain a flat back and hold the stretch for 20-30 seconds while breathing deeply into the tension.
- Inhale as you gently return to the upright starting position, then switch legs and repeat.
Form checklist
- Keep your front knee straight but avoid locking it out aggressively.
- Hinge at the hips rather than rounding your lower or middle back.
- Keep your front foot flexed (toes toward shin) to intensify the stretch.
- Ensure your hips remain level and square, not tilting to one side.
Pro tips
- Think about pushing your tailbone back and up toward the ceiling to maximize the stretch at the hamstring's origin.
- Contract your quadriceps on the front leg; this uses reciprocal inhibition to help the hamstrings relax and lengthen further.
Make it harder
- Place your front heel on a small elevated block or step to increase the angle of the stretch.
- Reach toward your front foot with the opposite hand to incorporate a slight cross-body stretch for the outer hamstring.
