HOW: Get set-up seated if you’re performing this for the first time, the goal is to progress to standing. While keeping your arch lifted by doming your foot, spread your toes apart as far as you can, hold for a moment then return to starting position. When performed correctly, your arch will raise in height and all of your toes will spread apart from one another.
FEEL: You should feel your foot and arch muscles working with this exercise, you should also feel your arch tighten up and the muscles in between your toes working.
COMPENSATION: Try to keep the rest of your foot and your heel on the ground, try to keep your toes in line with one another, do not excessively extend/flex your big/little toe, do not move your foot side-to-side
