Get down on all fours and place the soles of your feet against a flat wall. Your hands should be directly under your shoulders. Once in position, start to walk your feet up the wall backwards behind you.
Walk your hands back towards the wall at the same time. Ideally, you should keep going until your chest is flat against the wall, but stop where you feel comfortable. Hold for 10 seconds, then reverse to the starting position.
