most of the time people automatically view being stared at in the gym as a bad thing, or they let the fear of being stared at psych them out of going to the gym. there are so many reasons why someone could be staring at you in the gym and it doesn't necessarily have to be bad. they could like your outfit, or be in awe. it doesn't have to mean they're judging you, but they very well could be judging you in a good way!
