Setup
- Start on all fours in a tabletop position with your hands under your shoulders and knees under your hips.
- Extend one leg straight out to the side, keeping your foot flat on the floor and in line with your resting knee.
- Ensure the bent knee remains at a 90-degree angle with the inner side of the knee and ankle contacting the floor.
- Keep your spine neutral and your gaze directed slightly ahead of your hands.
How to do it
- Inhale to prepare, then exhale as you slowly sink your hips back toward the heel of your bent leg.
- Hold the deep stretch for the prescribed time, maintaining a slow and controlled breathing rhythm.
- Inhale as you gently rock your weight forward to return to the starting tabletop position.
- Complete all repetitions on one side before switching to the opposite leg.
Form checklist
- Keep the extended leg completely straight and the foot grounded.
- Maintain a flat, neutral spine without rounding or arching the lower back.
- Keep your hips square to the ground throughout the movement.
- Avoid letting the bent knee slide outward; keep it anchored under the hip.
Pro tips
- To maximize adductor engagement, imagine pulling your straight leg toward your midline while it stays fixed on the floor.
- Focus on 'tucking' your tailbone slightly to increase the stretch in the hip capsule and protect the erector spinae.
- Breathe deeply into the pelvic floor to encourage the nervous system to relax into the range of motion.
Make it harder
- Drop down onto your forearms to lower your center of gravity and deepen the hip opening.
- Slowly rotate the toes of the extended leg toward the ceiling to shift the stretch more into the hamstrings.
