Well day 3 of P90X is in the books. According to my HRM I burned 1144 calories in 65 mins. I did the Shoulders & Arms + Ab Ripper X. I actually completed 142 reps of the 339 they do on the DVD. On day 1 I was only able to complete 72. I felt a better today though. Great workout. Tomorrow is Yoga X. I will feel good to stretch.
