Hey Bro, I gotta Bowflex I'll sell ya.
I love the workout on it, but it won't fit in my room at my fraternity house so its just sitting at my parents crib gathering dust. And everyone's right, its platform is based on circuit training and does very well for toning, tightening, and with proper diet, defining. For putting on mass I wouldn't recommend it though. If you're interested, PM me about it, I'll make you a sweet ass deal.
