It takes a lot of body control to win a championship in 5 different weight classes. A fighter must know his body then train and eat accordingly so as to peak during the specific time of the fight. For the most part, fighters keep their training schedules and eating habits private so as not to tip off the opponent. It could be that successful fighters workout all day, eat right and don’t drink or do drugs. It’s also possible that some of these fighters are just blessed with 1% body fat and require less effort to maintain their desired weight. Either way, the following fighters have perfected the art of winning in different weight classes.
