I used to be a "gym rat" but the general "guy culture" at most gyms is thinly veiled bully behavior. I can not count the number of times I interrupted normal, buff, and outright fat guys giving less-than-babe-status women grief. I finally found myself getting prepared for anger when going to the gym, and after switching gyms a number of times I gave up and now work out in parks and at home, away from the public assholes that ruin it for all but the beautiful.
