Performed this workout w/ active 3 minute rest periods ie. I rowed, on my concept2, at a moderate pace during the 3 minute rest period. That really increased the calories burned during this workout as well as the workout intensity and amount of sweat produced. One could add a 300 to 400 meter easy run as a substitute for rowing.
I also did this after a night and day of fasting. Had plenty of energy at 6:45 PM today after having last eaten at 7 PM last evening.
