You've been able to gain mass with the bowflex? While the reviews I have read about it are mostly positive, I still can't help but think something else might be better. I admit however, that I've never used a bowflex. We have the video, and she printed out the manual.
As I said earlier, my wife wants one (the Ultimate model), but for $2000 I can get a body solid product with free weights and a cable machine + a bit more and have it shipped for free. Whereas a BF would be $2000 + $200 shipping. double that shipping if she were to return it.
We both want some equipment in the house, but we are both wanting different things. She brought up space, but the ultimate model folded is 28x48. The stuff I want doesn't fold up, and it's big (84x54" in foot print). It's the max resistance that I worry about the most on the bowflex. With free weights, I could always go buy more plates to add more weight if I wanted too.
I was looking at the Body solid EXM3000 selectorized model, but thinking a bench with a smith machine and some of the add ons would take care of what we both want to do (and be cheaper). She wants to tone up, I want to build up.
I'd be interested in hearing about anyone gaining mass with the BF. Right now, I'm doubtful of how much it can do.
