How to do it
Setup
- Lie face-up on a mat with your knees bent and feet flat on the floor, keeping your legs together.
- Extend your arms straight out to your sides at shoulder height with palms facing down to anchor your upper body.
Movement
- Keeping your knees and feet glued together, slowly lower your knees toward the floor on one side.
- Lower only as far as you can while keeping both shoulder blades flat against the mat.
- Pause for a brief stretch across the hip, outer glute, and lower back.
- Engage your midsection to smoothly draw your knees back to the upright starting position.
- Repeat the motion in the opposite direction.
Breathing
Inhale smoothly as you lower your knees to the side, and exhale as you engage your core to return to center.
Cues
- Shoulders glued to the floor
- Knees stay stacked
- Move with control
Common faults
- Lifting the opposite shoulder off the floor to force the knees down.
- Stop the descent as soon as the opposing shoulder begins to peel off the mat; prioritize thoracic anchoring over knee depth.
- Allowing the knees to slide apart during the rotation.
- Keep gentle inward pressure between your inner knees and ankles throughout the movement.
- Using momentum to swing the legs side to side.
- Control the descent slowly and use your abdominal muscles to pull the legs back to the center.
Safety
- Move within a comfortable range of motion and avoid forcing the knees to the floor if you experience sharp lower back or hip pain.
