At 36, Walton is actually the youngest head coach in the NBA. Among his peers, he is far from alone in trying to find ways to preserve his health. The coaching lifestyle tests endurance and mental toughness, just as it does for players. Although most coaches have access to the same science, equipment and training staffs as players, they are typically left to their own devices when it comes to taking care of themselves.
While the Lakers have a robust medical staff, “their days are full with the players,” General Manager Mitch Kupchak said.
Because of that, the Lakers are taking extra steps to ensure Walton stays healthy and on the sidelines.
Supervising Walton’s pool workout that September morning was Josh Wright. Officially, his title is assistant to the head coach, a position created after Walton arrived. Wright’s duties are myriad, but first and foremost, he oversees a fitness regimen for Walton and the Lakers’ assistant coaches.
A former personal trainer with a kinesiology degree, Wright connected with Walton several years ago through Phil Jackson. Wright helped Jackson through the back and hip troubles that plagued the Hall of Fame coach throughout his tenure with the Lakers.
Some proactive stuff here from the franchise with Kerr, Phil and other coaches' health issues in mind.
