Labs vs. Strength: What Really Predicts How Long You’ll Live? | Ep. 407

  1. Labs vs. Strength: What Really Predicts How Long You’ll Live? | Ep. 407 Jeff Armstrong 1:05:57

We’ve been taught that Longevity lives in our lab results—cholesterol, blood sugar, inflammation markers. But what if your ability to grip, stand, walk, and produce force tells us more about your future than anything in your bloodwork?

In this episode, we explore the tension between traditional biomarkers and functional performance measures. Is longevity something we measure in a lab—or something we express through movement?

Dr. Jeff Armstrong and Corbin Bruton break down the most important lab markers for Aging well, the overlooked power of strength and aerobic capacity, and why the future of longevity may lie in integrating both.
