Setup
- Lie flat on your back on a mat with your legs fully extended.
- Keep your spine neutral and your head resting comfortably on the floor.
- Place your arms relaxed at your sides.
How to do it
- Bend one knee and bring it toward your chest, grasping your shin or the back of your thigh with both hands.
- Exhale as you gently pull the knee closer to your torso until you feel a comfortable stretch in your glute and lower back.
- Hold the position for 20-30 seconds while maintaining deep, rhythmic breathing.
- Inhale as you slowly lower the leg back to the starting position and repeat on the opposite side.
Form checklist
- Keep the extended leg flat on the floor to stabilize the pelvis.
- Ensure your shoulders and neck remain relaxed and in contact with the mat.
- Pull the knee straight toward the same-side shoulder, avoiding lateral flare.
- Keep your lower back pressed firmly into the floor throughout the hold.
Pro tips
- Flex the foot of the straight leg to engage the hip flexors on that side, which deepens the stretch on the bent leg.
- Focus on 'heavy hips'—imagine your pelvis sinking into the floor to maximize the release in the gluteal fibers.
Make it harder
- Perform a 'Double Knee to Chest' by pulling both legs in simultaneously to increase the stretch across the entire lumbar region.
- Gently tuck your chin toward your knee at the peak of the stretch to incorporate a neural glide for the spine.
