PS3 Move system like wii fitness

Okay, so I need to exercise more. I read all about the PS3 move and the games. I already have a PS3 so that is the way I will go I guess. It is $150 for what I want to get started. That really isn't bad considering I was looking at getting a new system before. I love games and I think playing one will be fun and make me want to exercise. I am going to bring home my hand weights too and start using them as well. I seem to be doing more things than sitting and watching TV but they all still involve sitting... like that won't work!
