Even though we believe that being deconditioned (having insufficient stress, which results in movements becoming out of practice) is the only form of being unfit, there are actually two other ways that can limit our physical capacity just as much: misuse (having improper technique as a result of a fixation on effort over form), and overuse (pushing through pain of repetitive stress despite under recovered diminishing returns).
Flow, or our optimal level of fitness, is achieved when we strike a balance between putting in sufficient but not excessive effort, properly building and challenging our technique, and experiencing exertional discomfort as opposed to distressed pain. We also want to avoid overusing, underusing, and misusing our bodies.
