That half hour weight workout becomes a two hour workout. In this sport, more is NOT better, in fact, more is worse. I think there's no less amount of drug use in football, basketball, gymnastics, wrestling, not just body building. When I was competing we had mandatory IOC which is International Olympic Committee random drug testing three times a year. They need to bring that back in all sports.
Power lifters are smaller.
It's muscle hypertrophy which means muscle swelling. Muscles appear to be bigger, but it doesn't mean the fibers are stronger than a power lifter, or a shot putter or a tennis players muscles. Body building pumps blood into the muscles, which increases the muscle fibers along with many other reasons. The muscles appear to be bigger. Any form of exercise will increase strength, but there are small men that are much stronger than some of the larger body builders.
