There is a 2nd component. Efficacy, as bfowler notes above is the 1st component. The 2nd is injury avoidance.

The best Pro athletes have successful, long term careers. They can make the games they play look effortless because they are so smooth, balanced, graceful and fluid.
But since all of us have different bodies what works best for any one of us is a function of our both our strengths and weaknesses, as well as the wisdom to listen to our bodies and walk that tightrope between too little and too much training.
