I just bought my Ab rocket a few weeks ago. I still haven't used it but I did try it out once I got it put together. I got the flex master to go with it too. The only problem I had was the resistance bands, they just weren't strong enough for me. I could go down and back up with ease (no resistance even with the strongest band). I'm kind of iffy about using it since I'm getting no resistance at all. Has anyone else used it and had results? Also, is there any way to get better resistance...maybe rig one up? Any ideas? Thanks a bunch!
