In this episode, I speak with Will Ahmed, founder and CEO of WHOOP. WHOOP isn’t just another wearable—it’s become a global movement, with over 9 million tags on TikTok—a massive sign of how deeply it’s shaping the conversation around self-quantification. You’ll learn: - WHOOP’s mission and what makes it unique—continuous 24/7 physiological data, actionable coaching, and innovations like ECG and blood pressure insights - WHOOP 5.0 and WHOOP MG hardware—ECG readings, detecting atrial fibrillation (AFib), and the challenge of noninvasive blood pressure tracking - WHOOP’s partnership with OpenAI—in-app data analysis, conversation via ChatGPT, and integration of user supplement, nutrition, and blood test data - The “Healthspan Score”—developed with the Buck Institute to quantify physiological age using nine validated metrics - Sleep-stage detection—the real story on cross-device variance and what population-level data reveals about recovery - Heart rate variability (HRV)—why it reflects autonomic nervous system health, and why trends matter more than absolute numbers - EMF/Bluetooth exposure—WHOOP’s offline modes This episode is a must-listen if you’ve ever wondered how continuous physiological tracking can actually guide your training and lifestyle. My favorite part? Never-before-heard sleep, HRV, and recovery insights on what WHOOP has discovered after tracking the data of millions of users.
