I hope I am right that it is best to work up to 3X 1minutes on the prerequisites. If so I am almost there on all of them, but not even close on a proper hollow hold.
My plan is to just do three sets of each for what feels like 80% of my max hold until I build up to the 3X 1minute.
At this point, is there any reason I should test my maximum hold time on each of the prereqs?
