I have a good client with it - actually he used to have it. A few years ago we traveled to Boston together for a meeting, and he had to lug his machine around (this is probably 2002 or so). It took up half his suitcase, and he bitched about it most of the trip, including during the big meeting we were in to folks who'd met him 30 minutes before.
About 4 years ago his daughter was diagnosed with leukemia (she's fine now), and after her recovery, he got involved in one of the exercise programs to raise money for research. Apparently it was her suggestion, but he's dropped a bunch of weight (I'd guess about 75 lbs.). More importantly, he hasn't needed to use his machine in a few years.
So, yeah, hit the gym, fattie.
It will do more than make you look buff.
