You should go to the gym to train, not to watch other folks
I don't think it can be helped, especially the more exhausted I get, I notice it's harder to resist thinking about other people.
By the way, has anyone else noticed how everyone at the gym goes desperately out of their way to avoid eye contact and physical contact at all costs? I've never seen so many people awkwardly shuffle around, trying not to bump into each other while at the same time trying not to look at the other person.
