HOW: Get set up in a seated position barefoot with your foot resting on the ground. For this exercise keep the big toe down on the floor while lifting the other toes up towards the ceiling. Key here is to keep the arch of the foot strong for this exercise, don’t allow the foot to roll in while lifting the small toes up. This may give you a false sense of toe elevation here.
FEEL: You should feel your foot muscles working to perform this exercise and control the motion. It may be challenging and even frustrating at first, but try to relax your foot and 'try less' versus tensing up.
COMPENSATION: Avoid the urge to excessively flex and curl the big toe while it rests on the ground, just use a little pressure. Try to keep the rest of your leg above your foot/ankle 'quiet' and relaxed.
