Workout Update: 645 and XB Stretch Hybrid - Day 41

Day 41 was the cardio routine in 645. Again, this workout did increase the intensity a bit, but not so much that it made the workout too hard to do. As has been the case so far in Phase 2, this workout reuses some moves from prior workouts and introduces new moves or new variations on moves. Also like the other workouts, this one has seven exercises that are performed back-to-back with minimal rest between them for four rounds. In the first three rounds, you do each exercise for 45 seconds and in the last round for 30 seconds.
