Lisa,
I've been using it as a cardio. But only using 3 & 5 pound wts. Just not enough wt work for me to feel like it's a c/s. Of course I agree if you go heavier that it would be c/s.
PS: did you decide what to get next??? I'm eyeballing the cross training series. But for now I'm gonna focus on getting down the ones I have.
