Once a given capability is reached there will be a need for training just to maintain that level. Maintenance is training in that some will be required just to hang on.
A skilled practitioner is a competitor. Being a “competitor” doesn’t necessarily require winning formal competition. It could mean “competing” to continue to hit a certain measurable marker of skill, an indicator that you’ve still “got it.”
A Marine that trains rifle marksmanship until he always shoots in the 240+ range on Table One and then maintains that for the rest of his career (or, better still, the rest of his life) needs some on-going marksmanship training just to hold on. This isn’t a particularly high skill level but it’s achievable by anyone knowledgeable of what good shooting entails and willing to do a little work to get there. Merely maintaining such a level puts you in great standing among Marines and better-than-fair standing among good riflemen.
Maintaining what you’ve got is a form of progress, moreso for more physically demanding skills and capabilities. A person that earns a higher skill classification and then remains competitive within that peer group has maintained. More on this from Ross Enamait:
I like that this applies not just to conditioning and strength training, but to maintaining skill at sports, too. During the off season and whatnot.
