It isn't much to look at. The roof leaks, the interior is decorated with faded, autographed fight posters and a huge stained Mexican flag, and the sparring ring appears to be made entirely of duct tape. The workouts are throwbacks from a previous century, just running, shadow-boxing, skipping, jumping rope and hitting the heavy, double-end and speed bags. And if you want attention from a coach, you have to show some real dedication. But for $30 a month, follow Gene Vivero's cycle and you'll be in fighting shape in no time, whether you intend to become one of his many fighters representing at local and national Golden Gloves tournaments or just want to get in shape and aren't into the whole low-impact workout thing.
