The guys that I see with tonnes of women fighting over them are usually not jacked. Hell most of them aren't even in shape. Instead they are popular, exciting, adventurous, intriguing and yes often enough handsome.

"Oh look at how jacked that guy is, he's so alpha he must have the hottest bombshell of a girlfriend". Nope, he may well go home alone to his apartment to count his macros (and even his TRT). If he does have a girlfriend she's probably some chick he met at the gym who's just some average girl (nothing wrong with that). He doesn't have all these sorority looking bombshells fighting over him. The rebellious badboy, the intriguing traveller living off his trust fund, the party boy who may well die at 30, the handsome enigmatic quiet guy; these are examples of men who do well with women. Not some guy counting his calories; that's actually quite boring. He's actually equivalent to the conscientious nerdy engineer who thinks his 6 figure job is going to make the ladies go wild (lol).

If the gym guy suddenly improves his dating life drastically its due to other lifestyle changes and perhaps a decrease in inhibitions and increase in confidence. You do notice these self improvement types often get into the gym... then they go partying/clubbing more, trying to catch up to the validation they wish they had in college. They do anything to improve their social standing (which is what self improvement really is if we're being honest).

But seriously you are wasting your life thinking the gym will actually improve your dating life. Muscles on an autist is like putting lipstick on a pig. You have to fix the real reason you're unattractive (if possible). I don't see women fawning over muscles, instead fawning over other things.

I say this as a gymgoer myself. However I go to the gym so I can eat more food without getting fat, not to attract women.
