Stand up straight with your feet hips width apart.
Fix a resistance band securely under one foot with the other end held in your hand on the same side.
With your arm relaxed by your side, gather up some tension in the band.
Keeping your back upright and gaze directly ahead, lean to your side away from the band.
Slide your free hand directly down the side of your thigh, making sure you do not allow your body to lean forwards.
Once you have reached as far as you can go, control the movement as you slowly return to the starting position.
