The aggressive pursuit of maximum possible muscle mass and physical development — taken to its logical extreme. Buff maxxing isn't just going to the gym; it's optimizing every variable: periodization, sleep, nutrition timing, supplementation, recovery tools. The 'maxxing' suffix implies a completionist mindset where ordinary effort isn't enough and every marginal gain gets chased. Common in self-improvement and fitness communities that treat the human body as a project to be fully optimized rather than maintained.
Cold plunges, four meals, and a 5 AM alarm — bro is buff maxxing at a clinical level.
