A few things you can do to prevent undue joint strain.
Elbow, wrist and joint braces, or guards, not only prevent injury but also reduce the load on joints. Ask your doctor if braces may alleviate some of your joint stress and, who knows, perhaps improve your game.
Don't stomp your feet.
Research shows pounding exercises like kickboxing, step aerobics and more can be tough on joints. Switch to low-impact activities like biking and swimming that offer the same calorie-burning benefits without the painful pounding.
