Setup
- Kneel on a padded mat or soft surface with your knees hip-width apart.
- Place a sturdy chair either directly in front of you or to your side within easy reach.
- Position your torso upright with your hips fully extended and your glutes squeezed.
- Lightly place one or both hands on the chair for balance and support.
How to do it
- Inhale and slowly lean your entire torso backward as a single unit, hinging only at the knees while keeping your hips locked.
- Lower yourself only as far as you can maintain a straight line from your knees to your head.
- Exhale and engage your quadriceps to pull your body back to the starting vertical position.
- Maintain a slow and controlled tempo, focusing on a 3-second descent and a 1-second ascent.
Form checklist
- Keep your glutes tight to prevent your hips from hinging or sitting back toward your heels.
- Maintain a neutral spine and avoid arching your lower back as you lean.
- Use the chair only for balance; do not use your arms to pull yourself back up.
- Ensure your knees stay parallel and do not flare outward during the movement.
Pro tips
- Focus on driving your shins and the tops of your feet into the floor to initiate the upward movement.
- Maintain a slight posterior pelvic tilt (tucking your tailbone) to maximize the stretch on the rectus femoris muscle of the quad.
Make it harder
- Gradually reduce the hand pressure on the chair until you are using only one finger for balance.
- Increase the depth of the lean to move your torso closer to the floor, increasing the lever arm and resistance.
