Tim Grover, the trainer who worked directly with Michael Jordan, Kobe Bryant, and Dwyane Wade during some of the most dominant stretches of their careers, built Relentless around a direct argument that most people never actually discover what they're capable of because they stop pushing the moment real discomfort sets in, well short of any genuine physical or mental limit. Drawing on his own firsthand observations training some of the most competitive athletes in recent sports history, Grover categorizes people into three types, cleaners, closers, and cooolers, based on how they respond under pressure when a situation genuinely demands more than comfortable effort. The book's blunt, occasionally confrontational tone reflects Grover's actual coaching style, refusing to soften its central challenge that most readers have never come close to testing their real capacity.
