Being muscular doesn’t automatically mean being healthy.

In this deep-dive episode, we explore a counterintuitive but critical topic: why high muscle mass paired with low cardiovascular fitness can increase health risks rather than reduce them.

We unpack the research linking low VO₂ max to heart disease and early mortality, explain why muscle alone doesn’t protect the cardiovascular system, and explore the real-world consequences — from poor recovery to elevated blood pressure and chronic fatigue.

Using athlete comparisons, we show why hybrid fitness, strength and cardio, is the true sweet spot for performance, longevity, and quality of life.

If you care about living longer and performing better, this is a must-listen.
