Grip Strengthening with a Tennis Ball
These exercises should only be performed after evaluation by a qualified medical professional and under their instruction. Should you experience pain or discomfort while doing an exercise, stop immediately.
Sit comfortably in an upright position. Your right elbow is bent to 90 degrees and your right hand is holding a tennis ball in a palm-up position.
Next, firmly squeeze the tennis ball with your right hand. You'll feel the muscular contraction in your right forearm and hand. Relax and return to the starting position.
