HOW: Place a resistance band around your forefoot. Use your other foot to apply a line of resistance that is to the outside and closer than your working ankle (shown in the video). Your goal is to slowly push your ankle in a down + inwards direction in a diagonal line. Point your ankle down and in. Slowly return back to the starting position.
FEEL: You should feel the muscles on the inside 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.
