Workout Update: 654 Cardio/Lift 4 Hybrid: Day 2

 On Day 2, I did 645 cardio in the morning and Lift 4's back and biceps circuit in the evening. I again used the same amount of weight for the exercises that I ended the last round with. Even so, because the workout switched up from the last two weeks of the program, it was very challenging, and I struggled to finish the 10 reps in the third set.
