Sedentary Time, Mating Success, and HIIT Protocols

Today’s episode begins with two unconventional but remarkable Feats of Strength. After that, Eric presents a Research Review segment about the deleterious effects of sedentary time (even in people who regularly exercise), and some practical strategies for reducing sedentary time. Next, Greg reviews a study linking certain masculine traits to mating success, which has been spread widely (and misinterpreted widely) on social media. That’s followed by a brief segment about high-intensity interval training (HIIT), in which Eric clarifies some definitions and describes the wide range of protocols that fall under the “HIIT” umbrella, which can be very adaptable and accessible to all fitness levels. Finally, the show closes with a music recommendation from Eric.
