Workout Update: Lift 4/Shaun 20/645 Cardio hybrid: Day 13

On day 13, I did the 645 cardio workout, immediately followed by Lift 4's stretching routine. I did not foam roll, however. Both went fine, and it did help to stretch after the cardio. I still have a long way to go to get my flexibility where I want it, but my main concern at this point is not backsliding.
