HOW: For this exercise secure a resistance band at the tip of your thumb. Stabilize the opposite end with your other hand, then take your thumb across your hand as if you’re making a number 4. Pull your thumb down towards your wrist then slowly release back up. This will be a very small movement.
FEEL: You will work the muscle on the front side of your thumb with this exercise.
COMPENSATION: Don’t let your wrist rotate, specifically inward (pronation), keep your palm up towards the ceiling.
