I've been doing TurboFire since Friday. We don't have a gym membership, so the only way I'm usually able to work out is through DVDs at home. TurboFire is a lot of fun, and I got up early this AM to start my day with it.
And our DVD player is apparently broken. It took me 35 minutes of cleaning, blowing on things, etc. to even get it to recognize the disc. The same disc and workout played on Friday night just fine, so I know it isn't the disc, but the player. Once I got it to (finally) recognize the disc, the player just skipped nonstop. So, that's awesome.
