HOW: Begin this exercise in a seated position with your ankle hanging comfortably off the edge of a table and the inner lower leg facing upwards. With the ISOTIB appropriately on your foot, lift your foot up towards the ceiling, pause for the given amount of time, and return your foot to the starting position.
FEEL: You will feel the muscles of your inner lower leg working to move your foot into ankle inversion.
COMPENSATION: Avoid having the motion come from your knee or hip joint. Keep your leg straight and relaxed with the motion only coming from the ankle joint.
