Dr. Kelly Starrett

It's the best book on embryology there is.

But he has this hypothesis that it's one of the ways that the body used to tune itself.

That we spend time, for example, loading and kneeling on the hip

re-approximates the hip into the socket.

We get better hip function after that, right?

We have all these mechanics that function better when the hip has sort of better congruency, is better centrated.

And all you need to do is sit on the ground or work on the ground or kneel on the ground.

And that happens automatically.

Most of the time when we're sitting, we're actually sitting on our femurs.

We're not even sitting on the part of our pelvis that really handles that weight, the ischial tuberosities, the sit bones.

And so his idea is, well, we can get into some of these fundamental shapes and patterns and restorations doing something we always used to do.

Two and a half million years, I mean, I'm a little fatter, your femur's a little longer, but 10,000 years ago, we're the same person.

What's changed?

Well, we don't ever get up and down off the grounds.

So suddenly you're like, oh, that yoga, that mat Pilates, those wrestling games, those things turn out to be hugely important.

When am I going to put that in?

I'm a busy working person.

I can do it in the evening sitting on the ground.

And you will see your wattage change.

You'll see your power change.
