i have always belived in those machines. the soloflex, bowflex, total gym........................seriously. for the no competitive athlete they are great.
one condition though...............
under no circumstances ever never ever follow the routine they give you. do a 5x5 / dc/ or wsb something other than what they tell you.
A very close friend of mine actually works for them!!! When I visit him we usually bust that thing out cause I'm not gonna pay $10 a day to go train at his local gym. All in all it's a good BB work out, you get mad pumps, but there's no real way to train heavy. It's by far the best machine like that on the market!!!
