It seems that most novices will have positive, linear progression during their initial phase....almost regardless of program. As time goes by, programs need *continual* (?) refinement and fine-tuning to achieve progression and PRs.
In theory, is there any reason you can't continually make such refining modifications to keep pace with your ever-growing, ever-adapting body? It seems like the "better" you get the harder it would be to keep pace.....does it become a game of adding relatively foreign challenges and stimulae -- like trying to master a gymnastic move, or some OL that has yet to be tapped -- and this rejuvenates your overall progress? A case of having to change goals altogether -- gain mass, subsequently re-shift overall program as such?
I look at some of Gant's latest evolutions, and even CFFootball.....can you stick with a set goal and genre of programing indefinitely and keep making improvements within that sphere, or at some point do you have to radically shift things (gain weight, e.g., master foreign move)?
Maybe I'm just missing a fundamental and simple concept about progression and programming.
