Weight Class In Bodybuilding

In order for bodybuilders to compete against men of similar size, the IFBB has instituted weight classes for all amateur competition. The normal men's weight classes are 70 kilograms (kg), 154 pounds (lbs); 80 kg, 176 lbs; 90 kg, 198 lbs; and over 90 kg. In a minority of competitions, particularly in the Far East, one additional class 65 kg, or 143 lbs is also contested.
