Slightly off the subject here, but...
I was in the gym one evening and this girl sat on the exercise bike next to me.
Her triceps were pulsating, massive, the first time I'd seen muscular arms on a woman, in the flesh. She then went on to do some bicep pull-ups and her guns must have been 16 inches, really peaked.
Needless to say I could not get off that bike for about 20 minutes because, errrr...
So I don't think I could handle a workout with Heather Armbrust for this reason!
