Workout Update: 645 and XB Stretch Hybrid - Day 45

Day 45 was a flexibility and mobility day, with the namesake routine in 645, and in XB I did the lower back six-minute routine.

The flexibility workout in 645 was good. It follows the same format as it has the entire time, seven total moves that are performed back-to-back, then you get a 45-second break. You do three rounds and then finish with box breath breathing.
