Workout Update: Lift 4/Shaun 20/645 Cardio hybrid: Day 43

Day 43 was the start of Week 7 in Lift 4, which is the first of the two shred weeks in which you switch up what body parts are being worked in the various workouts. In the morning, I did Pure Cardio, and in the evening, it was Chest and Back (circuit) in Lift 4. The circuit workout was very tough (since there was little to no rest until the end), although I was able to use the same amount of weight for all the exercises in each set of the workout.
