DAY 16: Cardio circuit

In the P90X world... they call my performance today, "doggin' it" - I have no idea where this term started... but I was not giving it my all. I did as many reps as I could... but I knew my performance was not stacking up to other times I've done this workout... I have no idea what was holding me back. I just didn't seem to have as much energy... There were a lot of swear words. And they were not used in jubilation. But, I got it done and that's the important part. :)
