Skeletal muscle is going to explain about 80% of the variance in your resting metabolic rate.

That's your faster, slow metabolism.

Again, 80% of the variance is going to be explained by how much lean muscle you have, for the most part.

So you don't need to be huge, but losing muscle is called sarcopenia.

You lose muscle faster than you should be with aging.

Highly associated with inflammatory states, reduced resting metabolic rate, which then goes right back to the equation.

Glucose regulation, all of these things start to happen.

Last fire hose, I know I'm going after it this little bit here, but this is a topic of clear passion to me, is you have the presence of strength as well as the act of the training itself.

So going through the strength training process has additional benefits to things like your central nervous system, brain, and neurological system.

The evidence is very clear.

Your physical brain will stay healthier in terms of white matter and things like that.

when you strength train.

It will stay around a lot longer.

There's actually a lot of research now that's starting to point to the fact that things like dementia and Alzheimer's, late onset specifically, is highly preventable.

And by highly, I mean it's an extraordinarily high number.

You'd have to get a neuroscientist on to really get numbers there.

But it is way more preventable than we realize, specifically from physical activity and exercise as not the only thing there, but a huge component to that.

Lastly, why?

Remember, the way that you move throughout the world has three big components to it.

So when you pick your leg up like that and you just shifted your toe, what ended up happening there is three things.
