Workout Update: Power-90 Master's Series Day 54

 Day 54 of the master's series workouts was the core cardio workout. It is definitely not my favorite of the group (mostly because of the Dreya Roll push-ups, which are a harder version of the Dreya Rolls in P90X, which I have never been able to do well). But, it is a very challenging workout, that could have easily replaced the core synergistics workout in P90x. I plan on doing the x-stretch routine today, and then tomorrow starting in with P90x chest and back.
