When It Comes To Physical Activity, One Size Does Not Fit All

Yes and no.

First, the trash from the researchers:

"A landmark University of Alberta study, analyzing a sample of over 275,000 individuals, has found that when it comes to participation in physical activity, one size does not fit all...

'Our results have important implications for the design of government interventions aimed at increasing physical activity,' says Humphreys. 'When developing these programs, we must take into account North America's diverse population. A program that increases participation in one population, say older adults and retirees, in a particular state, may not have the same effect on young married minority couples in another state.'"

This study is not "landmark."

It is more "skidmark" as in what some people find in their underwear.

Nor does it have "important implications." No matter who or what you are, there are certain criteria anyone must fulfill in order to get fitter.

There is no need to "take into account North America's diverse population."

That thinking is the trash that gets researchers more money, not the population any fitter.

All physical activity to improve fitness is governed by two laws and two laws only.

All of fitness is governed by three laws and three laws only (this includes nutritional fitness).

There is no avoiding this.

So in a very real sense, one size does fit all.

This is akin to "buy low, sell high" as the one principle that results in a profit.

And just as with "buy low, sell high" each person will have a different determination of what is "low" and what is "high."

This is the only area in which there is variation.

BUT, you cannot violate the principles of fitness and succeed. Period. End.
