And sometimes our athletes are like, really?

This doesn't feel athletic enough.

So I was like, what could we do to sort of simulate that?

And that's where I came up with the idea of the hip spin-up, which was –

fundamental positions of flexion and rotation of the hip, we touch some end range tissues, we throw some isometrics in, we make your spine work with your hips, just ground-based, don't need any equipment, can be scaled.

And it gives you a touch of like, hey, what is, am I at least at these full ranges of motion for a second today?

Because I think what ends up happening oftentimes is that we can live in a world

where we're not asked to actually do all the things our bodies can do.

And now we're having to be like, okay, here's your vitamin.

Here's your X and such to make up for the fact that we're not really doing the things we need to do with our bodies.

Well, the question here is, what should the hip be able to do, right?

And I say hip as in the chain, right?

But that's the big primary engine.

The spine is the first engine, but then we have these big primary engines of the hips and shoulders.

And what's interesting about that conversation is that if I ask people who are very sophisticated about their running training or their nutrition, I'm like, what should the hip be able to do?

What's normal?

What's far from normal?

What does every physician agree we should be able to do?

They have no idea.

What's normal hip flexion?
