Exercise is defined by its purpose

Exercise is a process to stimulate a muscular growth mechanism. This is a shortened version of the definition of exercise developed by Ken Hutchins. It is succinct by design to focus on the important issue: stimulate muscle growth. A lot of confusion is perpetrated by creating, expanding and repeating incorrect associations. This confusion has fueled animosity from those who practice nearly every form of physical activity in search of exercise credits to increase their self-worth. How dare you suggest that my favorite activity is not exercise?

Here’s an excerpt from another promotional email that I received that clearly illustrates the stupidity that is so rampant:


Get Your Daily Workout In – One Minute at a Time

The benefits of regular exercise can’t be overstated – reduced risk of disease, healthier weight, better mood, and longer life.  All great reasons to get moving – but many of us still struggle to fit exercise into our schedules.
Adults need at least 2.5 hours, or 150 minutes, of moderate aerobic exercise every week – plus a couple muscle-building workouts – just to maintain good health.
If that sounds like WAY more time than you have, consider this:
•     2.5 hours a week is only thirty minutes a day, five days a week – plus
you can exercise in ten-minute intervals throughout the day and still get all the health benefits of a full workout.
 •     There are plenty of ways to squeeze a few more minutes of exercise into your day:
– Park at the back of the lot and walk (briskly!) into the office.
– Take every other step on the stairs, just for the challenge of it.
– Do a dozen squats every time you get up from your desk.
– Speed walk around the parking lot during your lunch break.  Just ten                  minutes can get you about 1,000 extra steps!
– Do a brisk lap around the grocery store before you start shopping.
– Use heavy items – like laundry detergent or a bag of groceries – as                   weights for bicep curls.
– Do jumping jacks during the commercial breaks while watching television.
– Try pushups against the counter while you’re waiting for the kettle to boil.
•     Map out some activities that you can add to your daily routine – and then get started building that habit.  10 minutes here, 15 minutes there and before you know it you’re up to 30 minutes (or more) each day, enjoying all of those great health benefits!


It is completely inappropriate to use moderate and aerobic in describing exercise. also, “workout” is a sensational jargon term for “feeling exhausted”. It has nothing to do with muscle building stimulating growth. The title states one minute at a time. Since it’s all cumulative, then how about 2 seconds at a time? It is not cumulative. The level of highest intensity is most important. Stimulation is achieved when a threshold is crossed. If it isn’t crossed, then nothing lasting results. It f it is crossed, then time is required to allow the growth. Interrupting that growth process is counterproductive. I won’t even attempt to address the rest of the deception in this piece that is built on these incorrect assumptions.

When a term gets overused and misused its meaning gets lost. If exercise is not distinct from activity and not different from recreation, then why would we have so many words to designate the same thing? Consider exercises as used in elementary school math. A concept like fractions is introduced and explained and then at the end of the chapter, exercises are presented. They typically progress from basic to challenging. What is the purpose for a student doing the exercises? Is it to have the exercises done? Is it to get the correct answer? Or is it to stimulate growth in the student to be able to do more complex things than ever before and ever more complex things in the future. The problem has already been worked many times before by others. We have the answer already in the back of the book. The point is to stimulate growth. The point is not keeping the child quiet or off the streets, as good as those things are. They are merely side effects. The point is growth. It is a long term adaptation. A student may work through problems for half an hour and find that their ability to continue is waning. Is that really growth? No! Not immediately. Growth comes over time. Exercise is an extreme. Growth is the adaptation to counter the extreme. If it isn’t challenging it won’t stimulate a change.

Now carry this logically into the realm of other activities. Take work for example. Work is a measure of output. It is not a measure of effort or energy. Those are inputs. Is work exercise? I was told many times in my formative years that when I did physical labor that I had gotten “my exercise for the day”. If the purpose of work is to get as much output accomplished as possible then it would be quite antithetical to exercise. To accomplish work, it is best to conserve resources and be efficient. The only point is to reach the desired amount of output. It is highly recommended to use tools to aid the process and save energy. The less challenging a task can be made, the more capability one has to do further work.

How about sporting activities? What is the purpose when we participate? Realistically the purpose is one of two things: To win in a performance or to improve in a practice. Athletic activities involve such skilled movements that to improve our ability involves rehearsing the skill in order to become more efficient in the movement. This means using less energy for a given output or achieving a greater output for the amount of energy expended. Again, like work output, this is antithetical to exercise. Practice for an athletic activity is productive when it is performed precisely. When fatigue sets in and the practice becomes sloppy, then it is counterproductive. To carry a practice to the point of being physically challenging enough to be exercise is also dangerous. On the other hand, a performance in competition is likely to be taken to the physical extreme yet that extreme is not the purpose, but rather to avoid that extreme by employing the practiced skill and reaching a higher level of performance is the point.

What about recreational activities? It’s often stated that exercise makes you feel better, maybe that it energizes you. Aren’t these benefits the actual purpose of recreation? Are exercise and recreation the same thing? Sometimes? Always? Never? NEVER! Why are there 2 different words? Again Ken Hutchins’ work in “Exercise vs. Recreation” is a great asset to understanding. Exercise and recreation are two completely different things because they have very different purposes. An attempt to get both at the same time only serves to compromise the integrity of each so that neither is accomplished.

Exercise is prescribed for growth stimulation. Keep it brief, intense and infrequent.
