Workout Update: 645 Cardio/MBF Day 18

Day 18 was the last core cardio workout from MBF and, of course, in the evening the 15-minute cardio routine from 645. In the MBF workout, I was able to do seven full rounds and most of an eighth round during the AMRAP portion. So, that increased from five rounds in the first week to 7.8 rounds in week three. So, my cardio/stamina has improved.
