Lie on your front with your toes tucked in and hands on the floor close to your chest, with forearms vertical and neck long.
Push up off the floor with your body aligned through the heels to the top of your head.
Once your arms are straight continue to push slightly backwards letting your hips rise high.
Keep your knees straight or slightly bent and press your heels towards the floor.
Keep your ribs down and push trough your shoulders and upper back.
Then reverse the movement back to the starting position and repeat.
