HOW: Place a resistance band around your forefoot. Use your other foot to apply a line of resistance that is to the inside of your working ankle (shown in the video). Slowly push your ankle outwards. Imagine you are a car windshield wiper cleaning just the outside of the window. Slowly return back to the starting position.
FEEL: You should feel the muscles on the outside part of your calf working as you move your foot away from you.
COMPENSATION: Do not let the band pull your foot back into the starting position. Slowly bring your foot back in and fight the resistance of the band.
