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

On Day 4, I did the Shaun 20 pure cardio workout and Lift 4 shoulders (intervals) in the evening. All the HIIT today ended up being low impact because the moves in the Lift 4 workouts are the ones that are some of the hardest for me to do, but I did do a couple of unmodified no-jump burpees. The Shaun 20 workout was slightly easier than the first time I did it this week but it was still challenging.
