I do cross-country, which is definitly a great sport to get into. it isn't easy, an easy workout is running steady for an hour or more. however, it is excellent exercise and gives you lots and lots of endurance. not too great for building muscle, but it keeps me lean and fit. I would recommend this sport to anyone who needs excercise outside their MA classes. This sport is basically running, and lots of it. if you don't want to be on a team or don't have one accessible, just go for a run. i really like trails more than roads, its prettier and more fun.
