We always have to go to extremes on the internetThese threads always default to the roided out dudes as an example of what "hitting the gym" means. Even the OP used the word "bodybuilding" instead of working out. Right from the top you can tell they've never been in a weight-room
it's like WTF does bodybuilding and some awkward roided out dude on a beach have to do with hitting the gym
.

But most dudes are probably not going to see that big of a difference in dating outcomes from working out. If you have the time, sure... but if time/resources are limited I'd focus on other shyt like making more money and moving to a city where the dating climate is more favorable.
