Weight Class Rules & Regulations

Weight Cutting Process

Fighters must make weight during official weigh-ins, typically held 24-48 hours before the fight. The weight cutting process involves strict dieting, dehydration, and intense training camps to reach the required limit.

Championship Weight Requirements

For title fights, fighters must make the exact weight limit. For non-title fights, there's typically a 1-pound allowance. Missing weight can result in fines, fight cancellations, or catchweight bouts.

Moving Between Divisions

Many fighters compete in multiple weight classes throughout their careers. Some champions have even held titles in different divisions simultaneously, showcasing their versatility and skill across weight ranges.
