My husband ordered a Total Gym. There are different versions - ours is one of the cheaper models.
Hubby used it alot at first and really seemed to like it. Like so many folks, he's gradually lost interest and never touches it now, but that's just the way he is with exercise in general.
I've used it some and have found it to be very effective on most upper body exercises. I don't use it for lower body. The leg exercises seemed awkward to me. Free weight work - lunges, squats - just works better, IMHO.
I'd love to have a Bowflex, but the price is too high for us.
