Professor Sebastien Chastin joins the Common Good Podcast to talk about his groundbreaking research into "the perfect cocktail" of exercise and rest that will lead to longer and healthier lives. Professor Chastin outlines the "three-to-one" formula, where three minutes of physical activity offsets every hour spent sitting, and how he and a team of international researchers carried out their study. He also looks at his work into how exercise can reduce the risk of infectious diseases like the coronavirus by a third.
