Just do it? Better than nothing is not the standard.

Exercise may be the most important thing you can do for your health and well-being.

That's a bold statement, but I believe it's true.

The problem is that we've lowered the standard.

Nike told us, "Just do it."

As a call to action, it's brilliant. If you're doing nothing, then yes, doing something is almost always an improvement.

But "better than nothing" is not the same as "effective."

Those are two very different standards.

If your goal is simply to check the exercise box, almost anything qualifies. Take a walk. Lift a few weights. Ride a bike. Sweat a little. You'll be able to say you exercised.

If your goal is to become stronger, maintain your independence, reduce your risk of physical decline, and preserve your ability to live the life you want, then the question changes.

Not Did you exercise?

But Did your exercise create the adaptation you wanted?

Those are not the same question.

We accept effectiveness as the standard everywhere else. We don't celebrate a medication because it's better than taking nothing. We ask whether it works. We don't judge a business strategy by whether it keeps us busy. We judge it by whether it produces results.

Exercise deserves the same standard.

The body doesn't reward effort.

It responds to demand.

Not every exercise session creates enough demand to make the body adapt. Some sessions are too easy. Some are too random. Some are simply repeated because they feel familiar.

Being tired is not proof.

Sweating is not proof.

Time spent is not proof.

The only meaningful question is whether the body was given a reason to become stronger, more capable, and more resilient.

Don't confuse activity with effectiveness.

One fills time.

The other changes you.

If exercise is important—and I believe it is—then it deserves more than "better than nothing."

It deserves to be done well.
