And he makes it look so easy.

He does make it look easy, and people don't know how hard that is. The whole purpose of that is to give an athlete a greater sense of his or her body. When you get on that ball, there's no way to cheat. You have to fire your entire system, your entire kinetic chain—muscles, cells, nervous system—all components have to fire in order to do that without holding onto something. When they come in the first day, we have people kneel on a ball, and they can't do it.

It's like getting in a car that doesn't have four-wheel drive but you're going to take it up a mountain in snow anyway. You just saw someone else do it, so you’re like, ”Huh, well I'm going to drive up the mountain in a Toyota Corolla.”

I’m 28—if I want to have a long-term exercise regimen and be able to stay active, what are the things I need to start doing now to put myself in a position to be able to do that?

Number one: You've got to know what's going on with your body. That's always going to go back to getting a proper assessment. Number two is that your recovery has to match the training. Every time you train—even if you're training perfectly for your body's wants and needs—you're going to cause some imbalances, some muscle trauma. So you're going to need body work. You have to make sure you're getting the proper stretches in line for your body, and tissue work, and the right food. Sleep, staying hydrated. All of this goes hand-in-hand. It's like if you have a Formula One car or a fighter jet, you're not going put a bunch of bad gas and shitty oil in it. There's a system in place to make those two pieces into the machines they are, and the human body is the same way.

So if we take a guy like Draymond Green, or LeBron, or Oladipo, it’s such a grueling season. From the end of one game to the start of a next, how do you prepare to get your body back in top shape?

The three components I always suggest to my athletes: Number one, get in a cold tub after long games to calm the body down and get as much inflammation out of the body as possible. And some even like to do contrast: the hot and the cold. Number two, get the right food, and get hydrated. And then number three, sleep.

For example, this is kind of the protocol I was using with Oladipo during his playoff run: The minute you get off the court, get in that cold tub. After that, you need to get at least 1.5 liters of water in you. And then get a good meal in you. Stay away from the flour, stay away from the refined sugar, stay away from the gluten. Those are things that will cause internal inflammation. Lastly, you've got to get eight hours of sleep, at a minimum.

Especially with these athletes who are taking four- or five- hour flights on their day off—flying dehydrates you. A dehydrated muscle is like a dried sponge on the sink. If you take that sponge and you run it under water, you're creating a bunch of fluid. So you have to get as much new fluid to these areas as possible.

When you say "do contrast," does that just mean going from cold tub to hot shower?

We like to use five minutes hot, five minutes cold, five minutes hot, five minutes cold.
