Hi,
When doing the core and upper body workouts, I've always done all elements on the same day, one after the other, in the order presented on the course page.
I reach the last element somewhat tired, and progress slower with it. There are steps that I can preform in terms of volume and technique, but not tempo, but if I do them separately, I can reach the required tempo as well.
Is the order intentional, so the last element should be trained when more tired? I've noticed that in some cases people asked about separating the workout into several days and were told it's ok. If this is the case, when doing all three on the same day, should I rotate the order between them? Or should I measure readiness to move on to the next step (and\or achieve mastery) when "fresh"?
