I don't know if this bothers you, but there is something I need to get off my chest (pun intended)...
Ladies, I love that you are proud of your body and all, but please put on a shirt at the gym. A sports bra, bra being the key word here, is not an acceptable shirt at the gym. I am not just being a picky prude here, but a shirt is a way to keep sweat at bay. Nothing grosses me out more than the ladies who are at the gym for hours, mind you, sweating up a storm and rubbing on everything in their reach. Most weight machines require some type of upper body contact, not to mention the gross factor a sweaty, shirtless gym goer can add to the floor mats while doing abs. No one ever wipes down those mats either... but don't even get me started on that.
If you're proud of your figure, then more power to you. I am all for prancing around in your sports bra on an outside jog (with sunscreen, of course), just don't do it at the gym.
