Doing proper strengthening exercises can help prevent these injuries as well as enhance performance. Use of isometric exercises for the forearm and hand will improve grip control and minimize the effects of ball impact. Use of free weights or exercise equipment is suggested for strengthening shoulder and leg muscles. Abdominal curl ups and back extension exercises can be done for the trunk. Weight training should begin with low weights and slowly progress to heavier weights to prevent injuries to muscles and joints.
Tennis provides little in the way of Aerobic conditioning.
To attain aerobic conditioning an individual must exercise for 20-30 minutes continuously. Court endurance can be improved if the individual cross-trains in other activities such as swimming, cycling or jogging. Tennis does require anaerobic activities such as stops and starts and sudden surges at maximal speed. This can be worked on by simply running short sprints on the court, whether it be from side to side or baseline to net. A player can make up his own drills hitting against a wall or with a ball machine.
