Workout Update: 645 Cardio/Lift 4 Day 51

Day 51 was legs 50/50 in Lift 4 and 645 cardio. The Lift 4 workout was very tough. I was sweating like crazy even during the lift portion of the workout and was absolutely wiped out by the end of the HIIT. Needless to say, during the 645 workout, I did much lower-impact exercises.
