Workout Update: 645 and XB Stretch Hybrid - Day 80

Day 80 was flexibility day again. I did the lower back routine in XB and mobility and stability in 645.

The 645 routine actually added a couple of new moves, one of which I was very surprised I could do as well as I did. One of them was a stretch I could do when I was a lot younger and in martial arts, but have not been able to do it for a long time. I am also getting a bit better at the kick-through variations.
