Setup
- Start in a half-kneeling position with your right knee on the floor and your left foot flat in front of you.
- Ensure both knees are bent at approximately 90-degree angles with the torso perfectly upright.
- Place your hands on your hips or across your chest and engage your core to stabilize the spine.
- Perform a slight posterior pelvic tilt by tucking your tailbone under to pre-stretch the hip flexor.
How to do it
- Exhale and slowly shift your weight forward, driving your front knee toward your toes while keeping your torso vertical.
- Continue the forward glide until you feel a deep stretch in the front of the trailing hip and tension in the lead glute.
- Inhale and push through the front heel to return to the starting 90/90 position.
- Maintain a controlled tempo of 2 seconds forward, a 1-second pause at the peak stretch, and 2 seconds back.
Form checklist
- Keep your chest up and shoulders stacked directly over your hips throughout the movement.
- Do not allow your lower back to arch excessively as you move forward.
- Ensure the front knee stays aligned with the middle of the front foot, not caving inward.
- Keep the glute of the kneeling leg squeezed tight to maximize the stretch in the hip.
Pro tips
- Focus on 'pushing' the hip bone of the kneeling leg forward rather than just leaning your body weight into the front leg.
- Maintain a 'tall spine' as if a string is pulling the top of your head toward the ceiling to ensure proper alignment.
Make it harder
- Reach the arm on the same side as the kneeling leg toward the ceiling and lean slightly away from the stretch side.
- Place the back foot on a small elevation (like a yoga block) to increase the stretch on the rectus femoris.
