The Science (and Myths) of Health Tech: VO2 Max, Wearables & Longevity with Dr. Todd Schroeder

In this episode, we sit down with Dr. Todd Schroeder. USC professor, exercise physiologist, and co-founder of K2 Sciences, to explore what actually works when it comes to health and fitness technology. From wearables and VO2 max testing to EMG studies and AI-powered motion tracking, Dr. Schroeder breaks down the science behind the trends and shares what decades of clinical research really say. We cover what health tech matters (and which don't), how to think critically about the data you're getting, and what role tech should play in your health journey. Plus, we get into the realities of muscle loss, why sleep is your most underrated training tool, and how innovation is reshaping physical therapy. This episode will help you cut through the noise and think more critically about the role of technology in your health.
