Most climbers don't train (FYI - Projecting climbs inside is not training. That is just performance in a different venue.) Of the few climbers who train, most are self-coached. In self-coaching, by definition, the person both creates the training map and has to follow it. For any map to be useful, you need to know where you are, where you want to go, what is the fastest way between those two points, and what is interesting along the way.
A great article, part of an useful training map, can be found here.
