Know this:
99.9% of the attractive people in the gym started where you are now. Some were fat kids, others were skinny. Very few of us are born with just amazing genes. We all started somewhere. That guy benching 400lbs didn't just wake up one morning and decide to lift that, it took a lot of sweat and hardwork to get there. The chick on the eliptical all toned n sexy had to work for that body.
No one in the gym is watching you, hell I rarely notice anyone in gyms unless its crowded and I'm waiting to use something. Hell some people may offer tips and/or assistance.
