Workout Update: 645 and XB Stretch Hybrid - Day 55

Day 55 was the last day of Phase 2 in 645, which meant doing the cardio workout again. The routine is the same, seven moves back to back, and all are moves that have been done during the program (or slight variations on them). This time they only did three rounds and then a longer cooldown stretch at the end. My cardio is still not great, but it is getting better so the program was challenging. The seal jacks and the plank walkouts definitely wore me out in this workout.
