Gym Girls, why do they look at you?

In the gym I notice more and more Girls kind of staring at me. I Am not a succesfull person with the ladies. I actually have been told a lot that I am not attractive by Girls and they didn't look at me at all before too. I Look better now and am more confident in my body but the Girls that seem to stare at me in the gym are with their boyfriend or insanely attractive so attraction can't be the reason. I Looked at my form that is allright so not making a fool of myself and am not lifting that heavy that it is interesting.

So I have no clue on why they look is there a way to find out why without risking making a fool out of myself can I see at the way the look why it is and if yes how?
