Workout Update: 645 and XB Stretch Hybrid - Day 59

Day 59 was the flexibility day. In XB I did the lower back routine, and of course, in 645 it was the flexibility and mobility workout.

The 645 workout had quite a few new stretches mixed in with some that have been in prior workouts. The focus is again on hip, shoulder, and hamstring flexibility. It is not hard, but it definitely builds on the prior versions of the workout and is more challenging than in prior weeks.
