Shameless Run
The motto for choosing gym outfits is comfort, and the word is one that people can interpret in different ways. Wearing a towel around your waist to do some cardio on the treadmill is apparently this guy’s idea of being comfortable in your gym clothes.
Maybe he forgot to take it off and change into the proper fit, or this gym is in his basement. Either way, it’s a hazard to wear such clothes around elaborate fitness equipment like that where it can easily catch on something to break the machine or injure the user.
