ok, i've got a cardio question. i was readin some muscle fitness magazine a couple months ago and there was an article that rated alot of cardio equipment. anyways, the stationary bike was rated as poor. it's not really that bad is it? it's the only kind of cardio that i ever do. it keeps my heart rate up. i'm not exactly sure how high it's supposed to be, but i rode teh bike for an hour friday morning and it stayed around 140-150 the whole time. but, is this bike just a waste of my time or what?
