I've just always tried to separate boulder strength and endurance sessions. I certainly couldn't do an even half good PE/Endurance session tagged onto the end of a hard bouldering session, especially with campusing and shoulder exercises thrown in as well.
Cheers for the wisdom. Will split the sessions. What's ARC then?
climb with a manageable but definite pump in your forearms for 10-40 minutes.
ARC = no pump or very light pump, you know you're doing something but it's just a bit of extra blood flow
