So I mastered 1 scoop preworkout this morning, was about to go to the gym and do some lifts, a buddy coaxed me into INSANITY instead. He had a portable dvd player and we busted out the fit test and Cardio Power and Resistance. Great workout!!
I took some more before my afternoon workout, P90X Shoulders and Arms, my goodness the pump was amazing. I burned some good calories today.
