The UFC Performance Institute is recommending fighters stay within 10 percent of their weight class on fight night, per an expansive analysis by the facility released Monday.
In addition, the detailed study states that no more than 1.5 percent of an athlete’s body weight can be lost per week from only body fat, so any drop in weight “should plan to be less severe” in order to lose fat and not muscle. The recommendation is that fighters should be losing no more than two to three pounds per week through their weight descent to get down to their contracted weight.
