Hi, I'm Christine King, and I'm here today to show you how to strengthen a pitcher's wrist flexor. This is important for the velocity of a pitcher's throw so we really want to work on the strength of these muscles. All you need is a dumbbell. We're going to sit down and put our forearm on our thigh. The first position will be with the palm up. We'll gently curl the wrist, tightening the grip on the dumbbell and then opening the hand until the dumbbell just about falls out. Continue to curl and release about 15 to 20 repetitions. The second position is with the palm down, still forearm resting on the thigh. Same activity only in the opposite, the wrist will come up, you will tighten the upper forearm muscles and then release the wrist down. And then the third activity is with the arm extended so you may have to reduce your weight a little bit and with a neutral grip you will bring the weight up to the ceiling and then down to the floor, strengthening the forearm in a neutral grip.
