That's why in the book, which I know you haven't read, but if you do read it one day, no. I've been too busy. Yeah, I know. The section of the book where I write about stability, the analogy I use much against the desire of my publisher who hated it was that of a race car. Because again, you're thinking like, how does a race car explain stability?

Because again, you're thinking like, how does a race car explain stability?

But if anybody's driven a race car, or if you haven't, if you can take my word for it, one of the fundamental differences between a race car and a street car is that in a race car, you're transferring much more of that horsepower to the tires than you are in a street car. In a street car, a lot of energy seeps out because the chassis is not very stable. And you might say, well, why?

In a street car, a lot of energy seeps out because the chassis is not very stable. And you might say, well, why?

Well, in the case of a car, it's because it's more comfortable. Race cars are not being optimized for comfort, they're being optimized for performance. If you're optimizing for performance, you actually want more stability in the chassis and the suspension so that you're transmitting more force to the tires and the tires to the surface.

If you're optimizing for performance, you actually want more stability in the chassis and the suspension so that you're transmitting more force to the tires and the tires to the surface.

And similarly, when you think about an individual who has stability, they are able to transmit force much more directly to the outside world and they are able to receive force more safely from the outside world. And that's why no matter how long you ever gave me, I could never throw a hundred mile an hour fastball. And it's not that I don't have the strength.

I'm sure that if you put a 20 year old version of me next to a pitcher, I could have outdone him in every measure of strength. but I didn't have the stability to be in motion and stabilize the capsule of my shoulder and transmit force like a whip through my arm. You wouldn't look at a picture and think that's stability, but it's remarkable stability.

So when a client comes in at 10 squared and you do an assessment, how do you gauge how far they are away from being able to do... the dynamic movements? How are you gauging? What are you testing? What are you looking for to say, yeah, this person could start doing plyos.

Like for example, one thing I love doing, I don't have this on my centenary and decathlon list because we're being so strict about that only having 10 things, but I have kind of a side list of things that I want to be able to do. Like I want to know how late in life I can maintain certain metrics. And one of them is how late in life can I still do a broad jump of my height?

So why is that something I enjoy doing? Because it combines two things. It combines the concentric strength and power to be able to leap, but even more importantly, and at least as difficult, is it requires the eccentric strength to land and decelerate really quickly. How do you know when you look at someone if they're ready to do that, for example?

So just to be clear, people understand a wall squat is just level one.

Number one is failure constituted by pain or not doing it for a certain length of time.
