I'll encourage anyone who's serious about getting in shape, but these fat gym selfies are invariably just a shortcut to feelings of accomplishment. Their treadmill readouts wouldn't even be a decent warmup for most people, but they think the fact that they were in a gym makes them fit. They're not willing to actually put in the effort, they just want people to think they have. And when they fail to lose weight, or they get fatter, they can say, "See? I've been exercising and still can't lose weight! It's all genetics!"
