Start by shaping your hands as if you are giving “two thumbs up.” With your forearms parallel to the ground, and your thumbs pointing to the ceiling, start moving the thumbs individually in a circular motion. You can rotate clockwise for a while and after 10-15 seconds, you can change direction. You can also, if you’re talented enough, move the thumbs in a different direction at the same time. Start slowly in speed, and work your way up. You shouldn’t feel any pain during this exercise, so stop immediately if something doesn’t feel right. This exercise is a great way to stretch the thumbs and the tops of the hands.
