I tried to mix it up for a couple months after reading Sol's post about conjugate periodization. I had been climbing a lot of random stuff (no consistency) with the occasional hang board session (~once every other week). I then spent 2 months doing the following:
Easy bouldering warm-up
Project 1-2 routes at my limit (total 4-6 goes)
arm strength and core
ARC 30 min
Project 1-2 routes at my limit
4 sets on campus board
4 onsight/flash boulder problems
leg strength and core
Early in the training I ARCed a third day in the gym, later I climbed routes outside.
Early in the training I worked on boulder problems I could send easily and focused more on the ARCing, doing it as a warm-up both days. Later I treated the ARC as a warm-up and focused on pushing the harder boulder problems and the 4x4.
This definitely got me strong specifically for sport climbing, but I feel that having a bigger and more consistent climbing base would have paid off more. Also, you wouldn't want to do this for long, 8 weeks was a lot of intensity and my body had some lingering aches and pains.
Results: I sent a climb that I could have probably sent before with a lot of work but I did it easily in 4 tries and it upped my redpoint best two letter grades.
... my 2 cents.
one step, two steps... 10,000
