7.Thumb Extension
Strengthening the muscles of your thumbs can help you grab and lift heavy things like cans and bottles.
Put your hand flat on a table. Wrap a rubber band around your hand at the base of your finger joints.
Gently move your thumb away from your fingers as far as you can.
Hold for 30 to 60 seconds and release.
Repeat 10 to 15 times with both hands. You can do this exercise two to three times a week, but rest your hands for 48 hours in between sessions.
8.Thumb Flex
This exercise helps increase the range of motion in your thumbs.
Start with your hand out in front of you, palm up.
Extend your thumb away from your other fingers as far as you can. Then bend your thumb across your palm so it touches the base of your small finger.
Hold for 30 to 60 seconds.
Repeat at least four times with both thumbs.
