Summarize this article:

Lay two pieces of newspaper on top of each other, then fold them in half. Tear the paper with both hands until the paper is in tiny pieces, and repeat this exercise until you have ripped up all of the newspaper. Grip a resistance band with one hand, your fingers and your palm facing up. The other end of the resistance band will go underneath your feet. You should be standing with your elbow at your side and bent to 90 degrees. Use the other hand to grip right below your wrist as you curl your wrist and fingers up against the resistance band.  Perform 3 sets of 10 repetitions. Do this for both hands. This exercise will strengthen your wrists as well.
