Max Christie remembers sending LeBron James the text.

What do you do to stay ready? How are you recovering this fast?

Christie had just settled into his hotel room in Sacramento. It was a few days before Christmas, and the Lakers were in town to play the Kings the next day. And Christie, a 19-year-old rookie, wanted to know his future first-ballot Hall of Fame teammate’s secrets.

James, who has enjoyed unprecedented longevity in the NBA in part because of legendary recovery and treatment, sent Christie back a list of all of the tools and tactics he uses to stay spry as a 38-year-old in Year 20.

Christie has studied James’ pre- and postgame routines throughout the season. And for the past three weeks, he’s been implementing everything James shared with him, ranging from icing his knees and feet to using Normatec boots to cold showers and foam rolling and stretching.

“Everything he does from after the game in the locker room to before the game, how he gets ready for games,” Christie told The Athletic. “I mean, I’ve observed everything, and I’m trying to use everything that he’s been doing and putting it in my repertoire.”

At first, Christie didn’t notice much of a difference. But a few weeks in, he’s reaping the physical and mental benefits. The Lakers are too, as Christie has filled in nicely for the injured Austin Reaves and Lonnie Walker IV in recent weeks, with his 3-and-D skill set helping the team on both sides of the ball. His stats aren’t eye-popping, but he’s been dependable for a teenager who had question marks about his shot, strength and physicality a few months ago.
