Workout Update: 645 and XB Stretch Hybrid - Day 83

Day 83 was cardio in 645, and it was HARD. It was the most intense version of the cardio workouts in the program so far. It used the bands a lot, it had some plyometrics and some core. And, it moved fast. There were very few transition breaks and idle chit-chat as there had been in the prior cardio workouts. You pretty much go from move to move immediately. You do three "regular" rounds where each move goes for a minute, and then a fourth round in which you do each move for 30 seconds. I am someone who does not sweat a lot during cardio workouts but I was sweating a lot more than usual.
