I'm thinking of buying a $250 exercise package from an infomercial. I've been doing one of the exercises and it feels good. It stretches and stegnthens at the same time. I'm really tentative, though, since that's a good chunk of money and fitness things are more often than not a loose for me. However if it is a win, it's worth a lot to me. That's why I'd take the gamble.
Darn I wish I could just fine the love of DDR again.
Anyway, I have no idea what I'll decided, but if you're interested, it's the http://fluidity.com/ system. It appears to have good reviews.
