About this episode

This episode discusses the misconceptions about training intensity and provides insights on effective fitness metrics and protocols.

The truth most fitness shows won't tell you: we're overestimating both how MUCH and how HARD we train. We think we're training. We're really just moving. Statistically speaking, only 24% of American adults meet the federal exercise guidelines. This episode breaks down what "training hard" actually means for strength versus cardio, why vigorous intensity is non-negotiable for longevity (a 2018 JAMA study found low VO2 max is a stronger mortality predictor than smoking), the two metrics that reveal whether your training is working (VO2 max and resting heart rate), and the exact protocols to fix it — including the Norwegian 4x4, the most-studied HIIT protocol in the world.
