You may be in great shape, for the sort of exercise you do routinely. But if that's all you do, day after day, you may be setting yourself up for injury or mental burnout and that is not a good way to get fit. What can help prevent injury and burnout? Cross training.

Cross training is a great way to condition different muscle groups, develop a new set of skills, and reduce boredom that creeps in after months of the same exercise routines. Cross training also allows you the ability to vary the stress placed on specific muscles or even your cardiovascular system. After months of the same movements your body becomes extremely efficient performing those movements, and while that is great for competition, it limits the amount of overall fitness you possess and reduces the actual conditioning you get while training; rather than continuing to improve, you simply maintain a certain level of fitness. Cross training is also necessary to reduce the risk of injury from repetitive strain or overuse.
