Setup
- Lie face down on a flat surface with your legs extended straight and the tops of your feet resting on the floor.
- Place your palms flat on the ground directly underneath your shoulders.
- Tuck your elbows in close to your ribcage and keep your gaze toward the floor.
How to do it
- Inhale deeply and press through your palms to slowly lift your chest away from the floor.
- Keep your hips and thighs pressed firmly into the mat to isolate the stretch in the abdominal wall.
- Hold the peak position for 15-30 seconds while maintaining steady, deep breaths.
- Exhale as you slowly lower your torso back to the starting position with control.
Form checklist
- Keep your shoulders depressed and away from your ears.
- Avoid locking your elbows completely if it causes joint discomfort.
- Engage your glutes slightly to stabilize the pelvis and protect the lumbar spine.
- Distribute the curve evenly through the spine rather than hinging only at the lower back.
Pro tips
- Think about pulling your chest forward and 'up' to create space between your vertebrae before deepening the stretch.
- Breathe into your belly to create internal pressure that further stretches the abdominal fascia from the inside out.
Make it harder
- Slowly rotate your head and torso to look over one shoulder to increase the stretch on the opposite oblique.
- Walk your hands a few inches closer to your hips to increase the angle of extension, provided you have the spinal mobility.
