I was wondering if this product is anygood for strength training? I read alot about it on the internet and I came across many people that said that they had great results...Im so sick of my bench and wieghts, I want to find something quick so I dont have to change weights all the time from one dumbell to another. I mean, Im not that strong (yet), I weigh around 170 and bench 135..not to good, I read alot about this product of how "you lift your own weight" If this product helps me to actually lift "My own weight" im considering to buy it. Because if I can bench what I weigh, I will feel pretty good of myself...Thanks...
