"just f*ing workout"

The excessive amount of staring people do here finally got to me in a big bad way. Joe & I went to the gym on Thursday night & he decided to run while I lifted legs. Firstly, I am a woman lifting. Secondly, I am not doing the "pre-sanctioned lifting workout" that every other woman does (the trainers at the gym prescribe the same crappy routine for everyone). So, I was doing squats & dead lifts & I am noticing people are staring at me, but whatever, none of them are too close. So, it is my last set of dead lifts and there is a man standing not even 4 feet away completely staring at me. I mean, I turned over gave him a look, and he continued to stare. Finally I yelled at him in English, "just f*ing workout." He was clearly stunned, but responded "it's just different." So now I am even more fired up, and as I continue with my routine I started to think maybe I should apologize or whatever. So, I go tell Joe what happened & he said go apologize, so I went over and apologized & the guy was just like well no women here do that type of workout with such good form. And, I was just like "I get that, but that doesn't mean you can just stare." His response, "yeah, we tend to do that here." Just like, well, that's the way it is. But good thing I apologized, because turns out he is a trainer at one of the gym's other locations & he teaches Pilates at our gym, so yeah, would be kind of awkward if I happened to walk in his class sometime....
Clearly, the staring has been bothering me for a while here & I just snapped on this guy. It wasn't really fair, but at the same time I have no idea what makes these people think it is okay to just blatantly stare at you. There is nothing pleasant about it, and although they may not mean to be critical, it certainly tends to comes across that way sometimes. So my true fiesty liz colors finally shone through.....I am sure you guys have all been missing her.
