Setup
- Lie face down on a flat surface with your legs extended straight behind you.
- Place your palms flat on the floor directly under your shoulders, keeping your elbows tucked close to your ribs.
- Rest the tops of your feet on the floor with your toes pointed.
How to do it
- Inhale as you press through your palms to gently lift your chest off the floor, keeping your hips and pelvis grounded.
- Exhale as you lengthen your spine, looking slightly forward or upward without overextending the neck.
- Hold the peak stretch for 20-30 seconds while maintaining deep, controlled diaphragmatic breathing.
- Slowly lower your torso back to the starting position on a controlled exhale.
Form checklist
- Keep your shoulders depressed and away from your ears to avoid shrugging.
- Engage your glutes slightly to stabilize the pelvis and protect the lower back.
- Distribute the curve evenly through the entire spine rather than hinging only at the lower back.
- Keep a slight bend in the elbows if you feel any pinching in the lumbar spine.
Pro tips
- Focus on pulling your chest forward through your arms to maximize the stretch in the rectus abdominis.
- Imagine lengthening your spine from the crown of your head to create space between the vertebrae during the extension.
Make it harder
- Walk your hands 1-2 inches closer to your hips to increase the degree of spinal extension.
- Transition into an Upward Facing Dog by pressing into the tops of your feet to lift your thighs and knees off the floor.
