Define fitness how you choose.
That’s your right; it can be a subjective thing. If you wish to belong to a cult, you have a right to believe what you want. It is wise, though, that you seek to know more. Most people don’t know where to start. Do not infer that I’m claiming I know everything–in fact, the more I learn, the more I have realized that I need to learn. The sort of awakening to which I refer, though, does not happen without some attempt at discovery.
“The confidence of amateurs is the envy of professionals”–this, to me, represents the frame of mind owning so many practitioners in the fitness industry–but on the other end of the spectrum you find Bruce Lee saying, “My style is no style…” As this goes, it is difficult to maintain “no style” forever..and so even with an experienced coach there are preferences and go-to exercises that become prioritized more highly than others, but this often corresponds with the use of some underlying logic or systematic approach. Also, then, there are organizations which follow certain principles and standards–and there are coaches within these organizations who limit themselves within these parameters. With all this said, one coach is not another and one gym is not another–this is why I say I am an advocate for fitness; but not for the fitness industry, per se. I have been called old-school, but I prefer that over “closed-minded.”
