Workout Update: T25/Lift-4/645 Corrective and Foam Rolling- Day 43

Day 43 was the start of week 7 (the first shred week) in Lift 4 and Cardio 1.0 from T25. That means the muscle groupings get mixed up in Lift 4, with today's workout being the chest and back circuit workout. Even though this one does not have a HIIT component, it has the three-exercise, three-round burnout, which wipes you out (at least it wipes me out) as much as doing HIIT does.  The T25 workout in the morning again got a little bit easier, especially in the lunges (which have been difficult for me).
