If you participate in more than one sport or fitness activity--whether it’s golf in the summer and squash in the winter; running on Mondays and tennis on Tuesdays; or a combined daily workout at the gym--then you are cross-training. You may be doing it to achieve more complete fitness; to relieve the boredom of engaging in only one activity; to combat prohibitive weather conditions; or to prevent injuries; but you’re doing it, and 'Cross-Training' is the perfect companion. Find out the what, when, why, how, and where of cross-training, and: which muscles are worked by which sports; how to combine your favorite activities into an all-around workout; cross-training to enhance performance in a single sport or event; using cross-training to help avoid injury; working less common activities--like waterskiing, in-line skating, jazz dancing, and boxing--into your cross-training program; and much, much more.
