Workout Update: 645 Cardio/Lift 4 Day 10

Day 10 was the rest day in Lift 4, so I did the 645 cardio workout in the morning and the Lift 4 recovery routines in the evening. Both went fine. I was again switching up the HIIT moves in the 645 workout, this time incorporating the Heisman and squat jacks from Insanity and mountain climbers and soccer runs. That keeps me from getting bored in the workouts.
