Consistency

From a comment by Gordo on xtri


Protocol impacts the amount of "work" that we can absorb and, ultimately, "work absorbed" is what determines performance. So the plan (or person) that enhances our ability to absorb training is what proves optimal over the long run. That is probably why discussions over training protocol are a lot like discussions over nutrition. At a deep level, we know that our own choices are what determine results. It is also why the best coaches are the people the figure out how to get their athletes to absorb the most training, not the guys with the best scientific knowledge.

Many coaches allude to the fact that they have a superior method. I'd be wary of those people. The best coaches that I've met are the ones that admit that they get nearly as much wrong as they get right.
