“Everyone wants to know: What should a workout actually consist of? And first of all—let me say this: the most important thing to do is SOMETHING. ANYTHING. Walk. Jog. Calisthenics. Swim. Lift some weights. Hike. Stretch. Do burpees. Play a game of basketball or go get on the jiu-jitsu mat. Some people aren’t sure what to do for a workout—but that is often just an excuse. Exercise doesn’t need to be some complex, multi-level, multi-dimensional, scientifically proven methodology. But it does need to be SOMETHING.”
