(CNN)Everyone knows about LeBron James and his fanatical workouts, but not many people know about the guy entrusted with keeping his billion-dollar body in shape.

Mike Mancias would like to keep it that way.
The Cleveland Cavaliers' athletic trainer has been working closely with the NBA's four-time MVP and global icon ever since he joined the team 14 years ago.
Along with overseeing drills, Mancias' duties encompass everything from keeping tabs on James' diet, to preparing his recovery fluids, to flushing out lactic acid from his body after big games.
Over the years, Mancias has become inseparable from James, who once dubbed him "one of the best trainers in the world." He has shadowed him during All-Star breaks, Olympic duties and, crucially, his grueling offseason workouts.
"He's family, and so it goes beyond basketball and beyond anything on the hardwood," Mancias, 40, tells CNN of their relationship. "He trusts me and I trust him, so it's all good."
