(HealthDay News) -- Cross training involves varying your fitness regimen with a host of different activities.

Here are some benefits of cross training, courtesy of the American Academy of Orthopaedic Surgeons:

Cross training allows you to work your entire body, rather than strengthening just one area.A good program includes weight-training exercises (weight lifting, for example), aerobics (stair climbing), and flexibility exercises (yoga).Rotating between several types of exercise keeps your routine fresh, fun and prevents boredom.Overuse injuries are less likely, since muscles aren't used in the same way all of the time.Using muscles throughout the body can help you adapt better to new sports and activities.
