Workout Update: Lift 4/Shaun 20/645 Cardio hybrid: Day 37

Day 37 was the back and biceps (50/50) workout in Lift 4 (which I did in the evening) and the Cardio Circuit workout from Shaun 20. Both workouts went okay. I was able to use the increased weight for all sets of the lifting exercises in each block of exercises in Lift 4, although it was a challenge to finish off the wide biceps curls in the last set.
