Workout Update: 645 Cardio/MBF Day 9

Day 9 was 645 cardio in the morning and the core circuit workout from MBF in the evening. Both workouts went pretty well. Most of the core circuit workout repeats the same workout from last Tuesday. The biggest changes are to the core blocks in which mountain climbers are swapped out for plank jacks and you do exercises like flutter kicks and side planks. All of the exercises in the four-minute AMRAP block are the same, however. I was able to get a little over five rounds done in the AMRAP block, which is a little better than last week.
