I use the bowflex blaze cause it was on sale

But I find the rods to be pretty optimistic, XD it tells me I can do 70lb bicep curls pretty easily and bench 100, I can probably do half....
But yeah no, As long as you feel the resistance and the burn it really does work, I like it because it's fairly quiet as opposed to my old home gym with the metal weights that go clang clang when you use them so you can't listen to music as easily
Plus it looks good as a piece of furniture
