Eight hours of sleep
Protecting a full night in bed as a training input, not a leftover
Eight or more hours in bed, treated as non-negotiable and put in the calendar like a workout. Athletes call sleep the point where training turns into fitness. They also describe a clear gap between what they can do the day after a full night and the day after a short one. In practice the protocol comes down to three things: a fixed bedtime, a wind-down that starts well before it, and some way of quieting racing thoughts once the lights are off, whether a breathing count, a body scan or a slow mental walk around the room.

Eight hours is his stated minimum, and in a 2022 Q&A he put sleep level with two weekly rest days at the top of his priority list, calling it crucial for growth as a bodybuilder. Train hard every day, he adds, and you probably will not sleep well or recover.

By his own account in a 2025 Whoop clip, bed is around 11 to 12 and the alarm around 8.30, which works out at eight and a half hours or more in bed. He puts that consistency above everything else for what he calls health-span.

He says eight hours makes a big difference to how he feels, and that he tries hard to make it a priority. Decision quality beats decision volume for him. So cutting sleep to gain a couple of extra hours buys productivity that, in his words, might be an illusion.
