Plyometrics are damn fun. I love campusing. It is a pure expression of power as possible in climbing.
Although it is the most common tool for maximal (max) effort work in climbing, it is not the optimal tool.
Campusing, by its very nature, is non-linear. If your campus board personal record is 1-4-6, 1-4-7 is a quantum leap away.
However if a hangboard is used for max effort work, it is simple to make linear gains. I can add or subtract just a 1/2 lb at time.
It is easier to get from point A to B by taking steps (not leaps).
