Nah bruh, most gym communities are pretty welcoming places. I love seeing fat folks making an effort - how the hell are you going to give someone a hard time for trying to make themselves better? That’s pathetic and I don’t think that happens much at all. I’m on the other end being a wimpy twig, I step on machine that a 50yr old woman just steps off and I cut the weight in half of what she had it on and start grunting. I’d be an easy target I guess if people wanted to be jerks, but I’ve seen nothing but respect thankfully.
