Thanks for getting back to me. Your article that I posted about just seemed confusing. You introduced it with the three core movements PER W/O with 2 PR zones alternating, three W/O per week. But, when I studied the example you laid out at the end of the article, you had three core movements PER WEEK (1 per W/O) and 3 PR zones alternating?! The example was easy to follow, but I hesistated just because I wanted to clarify exactly what the design is supposed to be.
