HOW: Start in a seated position with your heel on an elevated surface and your foot hanging off. Allow your toes to go down towards the floor and then bring your toes up towards the ceiling. Make sure to use a high enough surface for your foot so your foot can go as far down as possible.
FEEL: You should feel the muscles in the front of your shin working.
COMPENSATION: Don’t go down and up with your foot too fast, slow and controlled.
