Sit upright on a firm surface with your feet hip width apart.
Move forwards, so that you are sitting close to the edge.
Lean your weight onto one side of your pelvis, and lift the opposite side of your pelvis off the surface.
Place the lifted side slightly backwards to walk your bottom backwards.
Repeat this with the other side.
Continue 'walking backwards' until you are sitting with your legs in front of you and off of the floor.
Complete the same movements in a forward motion to bring your feet back onto the floor.
