Wish I had you confidence. I wore just a regular skin tight t-shirt with no chest showing and leggings and I was doing my leg moves and I usually do them eyes closed so I can concentrate. I was done with my first rep and opened my eyes to see that there was a middle aged woman judging me like I have done something bad. I felt ashamed and left the gym before my last reps were done.
I’m a dude so I may not able to fully understand but sometimes you just gotta stop caring. People will judge and some, but what you can keep doing is lift. Never stop lifting, don’t let some pathetic old lady stop you from becoming the best version of yourself. Remember that.
