Workout Update: 645 Cardio/MBF Day 10

On day 10, I did 645 cardio in the morning and the upper body burn workout in MBF in the evening. The MBF workout was hard, even using light weights. The combination of exercises was hard, as was the fact that there was no rest once the workout started.  So, even on the exercises that I would normally use a heavier weight on, like rows, I was using avery light weight and still struggling.
