This is for the proform 600 S..I noticed on some peoples comments their machine only had 2 preset workouts. Mine has 4 preset workouts and includes hand weights with a place to put them on the actual machine. I had my doubts about a machine that would "fold" but if it really worked then I was willing to give it a shot since I have VERY limited space in my apartment. Rent in New York is ridiculous but space in New York is something of a dream. This machine is actually a dream, my dream machine. I get a fantastic workout and I never get bored when using the different workouts on the machine. ...review »
