Workout Update: 654 Cardio/Lift 4 Hybrid: Day 16

Day 16 was the back and biceps workout in Lift 4 and, of course, the 645 cardio routine in the morning. The Lift 4 workout was a circuit workout. Even though it had no cardio, it was tough. I did try to increase the amount of weight I was using for the exercises, but on some of them, I had to reduce the weight after the first set, especially in the second block.
