ELI5: Why do strongmen often have big guts and you never see body builders in "world strongest" competitions?
gpt
Bodybuilders alternate two kinds of training:

* "bulking"- where they train intensively to get bigger muscles and eat a lot, prioritizing stuff that helps grow muscles. But they also gain fat from that.
* "cutting"- where they go on a very strict diet to eliminate fat, while training lightly to maintain the muscles as much as possible.

The cutting actually makes the bodybuilder weaker, but is neccessary to achieve the "ripped" look. Right before the competition they also dehydrate themselves. It's not unheard of for bodybuilders to faint on stage.

Strongman don't do cutting because it doesn't help  them get strong. They just keep the fat they gain while building muscles.
