You can use traditional training methods like running and swimming as well as exercise on various machines or on in-line skates. Distribute the load of training among various body parts, thus reducing the risk of injury. Keep training while you are injured. When one body part is injured, you can train using different muscles and joints. Planning Your Program A cross-training program usually involves a combination of different exercises, each performed for a specific period.
Anaerobic exercise entails intense bursts of muscle activity.
Isometric exercise involves contracting the muscles against a fixed resistance without moving the joints, as in pushing against a wall. To improve aerobic fitness, for example, you can bike for 30 minutes. To increase strength, you can lift weights for 30 minutes. You can do one form of exercise each day, or both on the same day. If you do both on the same day, you can change the order in which you do them.
