I'm really sorry that happened and it made you so uncomfortable. What a bunch of jerks!! But you know what, screw them!!!!! And well done you for exercising!!!!!! Please don't let this isolated incident put you off. I totally understand why you found this hurtful, but these guys were just being jackas$es. The main thing is to keep on excercising because that is a great way to do something good for yourself. Honestly, whenever I see anyone exercising - whatever shape they're in - I think "good for them". And I'm sure that's what most people think. So, good for you!!!
