Set-up: Begin facing a wall, standing tall with a braced core and good posture. Inclining forward at the hips, without flexing or rounding your spine place your hands against the wall at substantially wider than shoulder width.
Movement: Now lean your weight into your hands until you feel a suitable amount of tension. Slowly lower your body to the wall, keeping your weight on your hands and without standing up at the hips. Push yourself - under control, and without momentum - back to the start position.
