Setup
- Sit on the floor with both legs extended straight in front of you in a staff pose.
- Bend your right knee and place the sole of your right foot firmly against your inner left thigh.
- Square your torso toward your extended left leg and flex your left foot so the toes point toward the ceiling.
How to do it
- Inhale deeply to lengthen your spine, reaching your arms toward the ceiling.
- Exhale as you hinge forward from the hips, reaching your hands toward your left foot, ankle, or shin depending on your flexibility.
- Hold the position for 30-60 seconds, breathing deeply into the back of the ribs and sinking deeper with every exhale.
- Inhale to slowly roll back up to a seated position and switch legs to repeat on the other side.
Form checklist
- Keep the extended leg's knee pressed toward the floor without locking it.
- Lead the movement with your chest and belly rather than rounding your forehead to your knee.
- Ensure both sit-bones remain grounded on the mat throughout the stretch.
- Keep your shoulders relaxed and away from your ears.
Pro tips
- Focus on the 'belly-to-thigh' connection; maintaining a flatter lower back will provide a more effective hamstring stretch than rounding the spine.
- If your hamstrings are very tight, place a small rolled-up towel under the knee of the extended leg to prevent strain.
Make it harder
- Reach past the sole of your foot and clasp your wrist with the opposite hand to deepen the fold.
- Actively press the knee of the bent leg into the floor to add an adductor and hip-opening component to the pose.
