Setup

  1. Lie face down on a flat surface with your legs extended straight behind you, tops of the feet pressing into the floor.
  2. Place your hands flat on the floor directly under your shoulders with fingers pointing forward.
  3. Tuck your elbows close to your ribcage and engage your glutes slightly to stabilize the lower back.

How to do it

  1. Exhale as you press through your palms to slowly lift your chest off the floor, keeping your hips and pelvis grounded.
  2. Inhale deeply into your belly at the top of the movement, holding the stretch for 15-30 seconds while maintaining a long neck.
  3. Slowly lower your torso back to the starting position with control, maintaining tension until your chest touches the floor.

Form checklist

  • Keep your shoulders depressed and away from your ears throughout the lift.
  • Maintain a slight bend in the elbows to avoid joint locking and keep tension on the muscles.
  • Ensure your hips stay in contact with the floor to maximize the stretch in the lower abdominals.
  • Avoid overextending the neck; keep your gaze forward or slightly upward.

Pro tips

  • Think about 'pulling' your chest forward through your arms rather than just pushing up to create more space in the abdominal wall.
  • To target the obliques, gently rotate your torso to look over one shoulder while in the peak stretch position, then repeat on the other side.

Make it harder

  • Walk your hands 1-2 inches closer to your hips before lifting to increase the degree of spinal extension and stretch depth.
  • Transition into an Upward Dog variation by pressing through the tops of your feet to lift your knees and thighs completely off the floor.
