Figure I need to up my cardio game a bit. Tired of the treadmill all the time. I've done the P90X cardio dvd's and while they did tend to get old, it was a good workout. I borrowed those to see if I liked it so I don't have them anymore. I don't plan on doing it in 60 days. I'll try and do it every other day with weight training the off day. We'll see how that goes.
