ive been lifting for a long time and i would like to have a gym at home.i see what the people look like on the commercials and i dont believe it.i tried a friend's SOLOFLEX a few years ago and i wore the hell out of it and didnt get anything out of it. well,BowFlex is saying that their machine gives 400 lbs of resistance.i have tried other machines and even manage to press 600 lbs(my best press was 455...nowhere near 600 lbs) on some electronic machine at some "gym".well,what i want to know is if you can do say 300 lbs on your bowflex,can you bench 300 lbs on freeweights?
