Tom Brady was a starting NFL quarterback for 22 seasons before retiring at the age of 45. Naturally, there was a lot of talk about his workouts andd fitness and training and diet, especially in the final years of his career. There were stories about him drinking 25 glasses of water a day, eating avocado ice cream and employing the TB12 diet to stay atop his game.
Ultimately, Brady did have to do a lot of maintenance to keep himself going, although he told the members of the Pivot podcast that things did get "blown out of proportion" at times (21:40 mark).
