At 40 years old, when many of his contemporaries have long retired, LeBron James stands tall as a titan of the NBA. He’s preparing to embark on his 23rd season, a phenomenal feat that few could ever have imagined. What is the secret to this incredible longevity? Is it just a matter of innate talent, or is there a costly secret he’s keeping?

1. The 40-Year-Old “King” and His Million-Dollar Investment
LeBron’s “immortality” has become a hot topic in the basketball world. Gary Payton II, a free agent, once dropped a bombshell: LeBron James spends nearly $2 million annually to maintain his body. This colossal figure, though denied by LeBron himself on The Pat McAfee Show, has sparked a debate about the level of investment an athlete makes in their physical well-being. “Man, I don’t know where the hell that s**t came from,” LeBron said, “but I do invest in my body for sure.”
Payton II’s claims, even if exaggerated, reveal a glimpse into how LeBron takes care of himself. It’s not just about high-intensity gym sessions but a scientific and expensive recovery process: soft tissue work, hyperbaric chambers, and ice baths. These are cutting-edge tools that help the body recover faster, minimize injuries, and prolong a career.
2. LeBron and Luka: Two Stars, One Philosophy
LeBron James’ story can be juxtaposed with a similar case: the much younger star, Luka Dončić. After the 2024-2025 season, Luka faced criticism for his conditioning. However, he responded with a spectacular transformation. Reports indicate that Luka shed 14kg (31 pounds) during the summer of 2025, preparing for FIBA EuroBasket and a new start with the Lakers.
This transformation wasn’t just a result of training but also of significant lifestyle changes: a scientific diet, improved sleep routines, and a revamped training program. And there’s a fascinating connection: Luka will be reunited with Jeremy Holsopple, the former head strength and conditioning coach of the Dallas Mavericks who has now joined the Lakers. This move shows that the Lakers are serious about investing in their physical support staff, a strategy LeBron has embraced for years.
3. The Lesson of Professionalism and Discipline
LeBron James has proven that age is just a number when you have enough discipline and professionalism. His posts of workouts at 5 a.m. are not just a show of pride but a declaration of absolute dedication. At 40, he is still fighting to maintain All-NBA form, with an impressive stat line of 24.4 points, 7.8 rebounds, and 8.2 assists in 70 games last season.
The investment in his body, whether it’s $2 million or less, is not an expense but a strategic investment. It’s the secret that has kept LeBron at the peak of his game for nearly 23 years, turning him from a talented player into a symbol of longevity and professionalism.
LeBron James is not just a great athlete; he is a model of discipline, professionalism, and foresight. His story, along with Luka Dončić’s, demonstrates that innate talent is only the beginning. To sustain greatness, one must make an unceasing investment in oneself, both physically and mentally. They aren’t just playing basketball; they are building a legacy, a lesson in how to triumph over the unforgiving nature of time.
