I will say this.
I've noticed I get more attention from people in general being in shape.
My problem was I still had/have a poor mentality that didn't go along with my looks.
I took some classes not too long ago and there was a girl in there a few years older than me that was feeling me.
She really let it be known.
But once she got a sense of my lack of confidence, she wasn't interested anymore.
She wasn't that good looking, but it felt good to get noticed and actually be seen as attractive to someone.
Unfortunately, my mentality wasn't as easy to train as my body was, pause.
I'm still growing though.
Went out to my buddies birthday party last weekend and when I left he told me one of his friends asked "yo who was that buff dude you work with? He made me realize I need to step it up in the gym"
I ain't even "buff" I'm just in shape, and your average dude in 2019 really isn't.
I do think looks/muscles can help, but you still need a mouthpiece/confidence to go with it.
