Thumb bend
Start in the same position and bend your thumb inward toward your palm and stretch for the bottom of the pinky finger with your thumb. If you can’t reach the pinky finger, don’t worry, stretch as far as you can. Repeat this exercise with each hand 10 times.
Make an “O”
Curve all your finger inward until they will form an “O” and hold them for a few seconds in this position. Straighten your fingers again and repeat this exercise 3-4 times daily on each hand. It’s very good to do it whenever your hands feel stiff.
