Sit on a step or low box, preferably with a back support. Extend both legs and cross the working leg over the non working leg.
Wrap the band around the balls of the working foot. Pass the band around the other foot as shown in the video.
Hold the end of the band with the same arm as the working foot. The ankle should be at 90° and turned outwards (eversion) before you start the movement
Turn the ankle in, without moving the rest of the leg.
