- Place the roller perpendicular to your spine and lie with your sacrum (the back of your pelvis) — not your spine — on the roller.
- Pull your left knee toward your chest, keeping your right heel on the ground. You should feel a stretch on the front of your right hip.
- To increase the stretch, reach your right arm over your head and open your left knee slightly out to the left.
- Hold for 30 seconds, then switch legs. Repeat as needed.
This is a passive, relaxing stretch that lengthens your psoas, one of the deep hip flexors.
