Workout Update: 645 Cardio/Lift 4 Hybrid: Day 55

Day 55 was the last day of this round of the hybrid workout. I just did 645 cardio in the evening. I decided to switch things up for the next round. Lift 4 is still going to be my primary workout, but I am going to incorporate a couple of the Shaun 20 workouts, which are shorter (20 minutes) low-impact versions of Insanity that Shaun T created when he was filming his Dig Deeper program and I will still do 645 cardio once or twice a week.
