Wrist curls are a common exercise that build muscle in the lower forearm and are extremely beneficial. You will need a curl bar and or free weights, and a bench. Place your arms on the bench while you sit on the ground, letting your hands hang off the side with the weight. Make sure that your palms are facing towards you. Then pull the weight up as a bicep curl, but use only the wrists. Do three sets for 12 reps.
Wrist extensions are almost the same basic workout as a wrist curl but instead of having your palms face towards you, you will have them facing towards the ground. In this exercise you will extend your wrists and bring them towards you. You will not need high weight to create stronger muscles. Do three sets for 12 reps.
Stress Ball Squeezes
This exercise is extremely simple and productive. All you need is a stress ball or something that can be squeezed and contracted. Squeeze the ball for the count of three and then relax and repeat. Complete three sets of 20. These three simple exercises will create much stronger wrists if done two to three times a week.
