So it appears to me that there have been some changes to the web interface, separating out all the various progressions into separate pages. While I'm appreciative, there seem to be a bunch of new progressions that need to be mastered, as well as a split between /PE exercises and /SE exercises.
So I was just wondering if I should be working both /PE exercises and /SE exercises in the one workout, or am I supposed to master all the preparatory exercises before the specific exercises?
