There’s plenty of evidence pointing to the benefits of exercise for creativity. Feeling good physically gets you in the right mood to focus and be productive. Exercise also forces you to have disconnected time (it’s tough to text or email while working out), and this allows you to reflect on whatever it is you’re working on. In a Stanford study, 90% of people were more creative after they exercised.
It’s no surprise that so many creative and successful people built exercise into their daily routines. Kurt Vonnegut took walks into the nearby town, swam laps, and did push-ups and sit-ups, Richard Branson runs every morning, and composers Beethoven and Tchaikovsky both walked daily.
