“A well-designed cross-training program includes a variety of alternating exercises that stress different methods of workout and affect different parts of the body. The American Academy of Orthopaedic Surgeons offers this list of cross-training benefits:
It's a total body workout that strengthens a variety of areas and muscles.
It prevents boredom, which could otherwise derail your exercise regimen.
It helps prepare the muscles for new forms of exercise.
It reduces the risk of an overuse injury stemming from repetitive movements of the same muscles.
In the event of an injury, you may not have to stop exercising. Instead, you can try other exercises that won't aggravate your injury.”
