In this segment, Ben Greenfield highlights recent research indicating that the most significant reduction in mortality comes from roughly ten minutes of vigorous activity each day. He emphasizes that this benefit does not require lengthy workouts such as 40‑minute WODs or 30‑minute spin classes. Instead, a brief, physically demanding effort—like a brisk uphill walk or a ten‑minute high‑intensity interval session on an Aerodyne bike—can achieve the needed intensity to improve health outcomes.

If you look at the biggest reduction in mortality, it resulted from around 10 minutes of vigorous activity per day. So, we are not talking about a 40 to 60-minute WOD. We're not talking about even a 30-minute spin class. We're literally talking 10 minutes of doing something that is pretty physically demanding on a daily basis. A lot of people can wrap their heads around 10 minutes, like just, you know, walk up that hill as briskly as possible for 10 minutes, or, you know, hop on an Aerodyne and jam through some intervals for about 10 minutes. That'll leave you pretty breathless.
