Hey Right Now, I also have occasional problems with my knees that stopped me from doing squats, lunges for the longest time. I finally broke down and bought a generic version of the "total gym" and it has made a HUGE difference!! I can do squats on that JUST FINE (and I was never able to do more than one at the gym), as well as other leg work. And because it's so adjustable, I can do all kinds of upper/lower body work without having to have a gym full of free weights. I bought mine because I got to the point where a) I was lifting free weights that were heavy enough for me to consider "is this the brightest thing for me to be lifting above my head when I'm ALONE?!!" and b) free weights were getting too expensive! At about a buck a pound, once you get up past about 35 pound dumbbells they become cost prohibitive.

The "total gym" knockoff I bought was from Walmart.com, here's the link, it was only $145.
