Workout Update: 645 Cardio/MBF Day 19

Day 19 was the final resistance-focused workout (full body burn) in MBF and the 15-minute cardio routine from 645. The MBF workout was very challenging again, especially in the unbalanced blocks. That was especially the case since some of the exercises were done standing on one foot. In the 645 workout, I still swapped out the jump lunges since my knee was still a bit sore.
