Workout Update: 654 Cardio/Lift 4 Hybrid: Day 30

On Day 30, I did not work out in the morning, so in the evening, I did the 645 cardio routine followed by Lift 4 back and biceps. The back and biceps this week is a circuit workout, and it is one of the hardest lifting routines in the program because of the fact that you are lifting heavier weights and have no rest between the exercises in the sets and minimal rest between sets and blocks. I had to drop the amount of weight I was using on several of the exercises to be able to maintain proper form.
