I have a new exercise gadget…. This plastic plate has a small dome on the bottom, so it’s tippy. The idea is to make controlled rotational movements, keeping the foot evenly applying pressure to the top, including the toes. I have pretty good ankle rotation—for now—and this will help me improve it. For now, I do the rotations sitting down. In the way-future, I will stand on this tippy platter, when my balance is MUCH better.
