Workout Update: 645 Cardio/MBF Day 3

On day 3, I did 645 cardio in the morning, and the MBF upper-body burn workout in the evening. Again, my weight selection was better this time in the MBF workout. I mostly used 10-15 lbs throughout the workout, which, because you are doing so many reps, quickly, with no rest between sets, is plenty.
