There are many exercises that can help treat, as well as PREVENT, tennis elbow. Here are a few to start with once the swelling has subsided in your joint. First, let's start with a stretch. Stretching will help minimize the stiffness that comes with joint injuries. This one focuses on the extensor and flexor muscles in your wrist: [expert demo] Hold your arm out straight in front of you with your palm up. Gently push down on your hand until you feel it in your forearm. Hold for 20 to 30 seconds. Flip your palm over and do the same on the other side. Repeat 2 to 3 times up to 5 times a day with each arm. Another exercise to try is wrist flexing. This move helps strengthen the muscles you've just stretched. Sit in a chair and rest your forearm on your knee or a table. The goal is to have only your wrist move. Holding a one-pound weight or a soup can slowly raise and lower your wrist ten times. Flip your arm over and do the same with your palm facing up. Do this three to five times a day. The last exercise we're going to talk about is the ball squeeze. Hold a tennis ball or even a balled up sock in your hand and squeeze. Keep squeezing for about six seconds and then release. Wait 10 seconds before repeating. Do this eight to 12 times on both hands. Even after your elbow has fully recovered, continue performing these exercises to avoid a repeat injury. For more ways to treat joint pain check out the rest of the videos in this series.
