I for one find nothing wrong with OP. Gamers in general have a stigma as most of you might know. I even use to feel embarrass to tell people I was a gamer because of how people perceived "gamers". It is known that most "gamers", PC gamers in general don't get the exercise they need. Nothing wrong with motivating and breaking stereotypes for other people. Sure there are the people that say this is egotistic and vain but don't we do this as well in the gaming world with rank, trophy's, achievements, skins, etc?
Akronus97 calling this "dumb" or whatever he said (to lazy to look at his post) and using sarcasm to try to gain sympathy for his point of view which is probably a deeper issue than guys showing their bicep lol.
Bro you need to do some hammer curls. Work that long head bruh.
I can honestly say my bicep is my weakest and smallest muscle
