You've got pumping iron, you've got Conan, you've got these things.

And you went from bad for my health to, oh my gosh, I can become a superhero.

And this empowered a generation of men, mostly.

Oh my gosh, I can become a physical superhero.

That was awesome, but the downside of that was everyone's association with him with strength training was muscle and bodybuilding.

And that is a very limited perspective of strength.

So scientifically, the people in this field were not strength training people.

The exercise physiologists, the nutrition scientists, and most were the 1960s through 90s, were all endurance folks.

And so you had no research being done.

I mean, you couldn't make the argument anymore that it was bad for your health, but there was no argument that it was really great for your health.

And they had a whole generation of kids like me.

who came up on that, but then also like science and started saying like, why aren't we doing studies on strength and high intensity stuff?

And well, that only lasted so long before work started coming out in that area.

And now it is so clear.

We have mechanism, we have epidemiological evidence, we have randomized control trials in men and women, young, old, and the research goes on.

Physical strength is one of the single strongest, pun intended, predictors of lifespan.

And so you've got lifespan, which is how long you're going to live.

You have health span, which people talk about now, which is how healthy are you within those years?

And now scientifically, we call that strength span, right?

And what they're saying is strength span, it's not the only thing that matters, but it's an important characteristic to your health span.
