Risks and Rewards

  The most significant contribution of Arthur Jones in developing the Nautilus principles and machines was not variable resistance through the full range of movement around one axis — but actually determining in what position that muscle had to be in to be fully contracted and fully relaxed — because it is the alternation between those muscular states — that determines the blood flow (circulation), and that is what produces health, growth, and optimal functioning. To him, that was incidental to developing machines that would be “foolproof” in ensuring that a person did precisely the right movement — and ensuring the results he “guaranteed.”

However, he did not account for trainees to actually subvert the intended functioning of his equipment — usually by lifting more weight than could be maintained by the proper performance. The machines were not designed to enable one to lift the most weights, but actually to exhaust the muscles using the least amount of resistance. All that got lost in training and selling machines to those who believed that using the most weight (resistance) was what produced optimal results — rather than by achieving the greatest difference in the state of muscular contraction and relaxation — just as the heart is effective in pumping blood out towards the extremities by that same action.

However, contrary to popular belief, the heart cannot force blood through the miles of capillaries, in which the purpose of that evolutionary design is to slow the blood down to where it can efficiently exchange gases with the resident tissue — at which point, contractions of the muscles at those extremities that contain the capillaries (at the head, hands, and feet), are effective at contracting (pumping) that blood back to towards the heart aided by the veins that allow blood to flow in only that direction back towards the heart (center of the body). It is two different set of blood vessels, and not just the heart providing the motive power for all the blood flow. That is the greatest misunderstanding of cardiovascular functioning and exercise effectiveness.

That is why exercise — or more specifically, contractions at those extremities, cause blood flow that ensures the elimination and removal of those accumulating and stagnant metabolic waste products (inflammation), and then allowing the new nutrients that ensure health, development and optimal functioning — as Nature intended. That process ensures the health and well-being of that individual — and not simply wanting it more than everybody else — as the jocks fancy it is.

So, far and away the most important thing, is to understand the science of this process — and not simply lifting the most weight possible. Thus the squat, deadlift, bench press are not the most effective exercises as often touted — but are simply those movements that allow one to use the most weight — regardless of whether they produce the desired results. As many have known and proven time and again, lifting the most weights possible, is a precursor for a career-ending injury, while a better objective for most, is to obtain the maximum benefits with the least amount of risk and injury. That is the wise strategy no matter what one is doing.

And hopefully by now, many more are entertaining how well they are functioning, or can function at all, when they are 75, rather than thinking that any price at 25, ensures their glory for the rest of their years. That has been the predictable failing in the traditional sports model as the template for lifelong fitness and health. It won’t matter how good one was at 25, when one is absolutely no good at 75 — and god forbid, even live another 25 years in that persistently declining condition.

After all, this is the 21st Century and the Space Age — and not just the continuation of the Cave man era — when life was assuredly, short, nasty and brutal. Then the future did not matter — and how one hoped to improve for it. It was just “one and done” — at every opportunity. And so life has persisted with that kind of attitude and outlook — rather than in thinking it is for a better tomorrow, and day after that… So yeah, excessive drinking, smoking, eating, driving recklessly and fast, has consequences and long term effects, and not taking the maximum risks just because one can.
