Workout Update: 645 Cardio/Lift 4 Day 23

Day 23 was the back and biceps Lift 50/50 workout in Lift 4 and, again, the cardio workout from 645. I again managed to use the extra weight from week 3 on the lift portion of the workout, and in the 645 cardio workout, I did less intense HIIT exercises that had less impact.
