Which is better Exercise euempiqnt?I am debating on Buying either the Ab Circle Pro or the Ab Glider something another.. If anyone has used either of these, I'd like some reviews on how well they worked. It's hard to trust commercials, and online reviews on the websites and things. Things like How comfortable it was.How easy it was to use.How often you had to use it.How much weight you had lost.etc.Please, and thank you!
