in fact that is what i hate most about the gym...the way some view it as a meatmarket/singles club. i am there to workout, to sweat, to stay in shape, to meditate. that is the last place i would want a man to leer at or approach me. unfortunately the women's only gyms don't have the serious workout equipment, neither in cardio or weights, that is really important if you're sincere about physical fitness. so therefore i go to the gym at "off" hours...late morning or late evening, when the before/after work singles mixer crowd won't be there.
oh, and as for how i dress? in a good sports bra, sensible workout pants, and a tank or t-shirt.
