Workout Update: Lift 4/Shaun 20/645 Cardio hybrid: Day 17

Day 17 was the rest day in Lift 4. So, I did the 645 cardio workout in the evening followed by the Lift 4 stretch routine. I did not do the foam rolling this evening, however. I started incorporating more exercises from Insanity (mostly modified as they are in Shaun 20) into the workout but still doing a couple of the exercises in the 645 cardio routine.
