His Shaolin master judged fitness by how fast a storm-tossed lake returned to calm. Modern exercise science measures almost the same thing. MORE EPISODES → https://thednaofthings.com/ Dr. Jeremy Koenig sits down with Walter Gjergja, co-founder of Zing Coach and a 32nd-generation Shaolin master, who spent eight years training at the Shaolin Temple before going on to study exercise physiology at Stanford. Gjergja explains how his master’s lake analogy lines up with heart rate recovery, which he calls perhaps the best marker of cardiovascular health, even better than VO2 max. He also describes how Zing’s AI coach, guardrailed by tens of thousands of rules, adjusts a long-term plan to daily sleep, HRV, and mobility data for the roughly 90% of gym goers who train without a personal trainer. By the end, the conversation turns on a question neither of them fully settles: as these systems learn more about us, how much of our own data should we actually see?

Gjergja describes eight years of study at the Shaolin Temple on Mount Song in Henan Province, where mornings started with chanting sutras and then running 1,500 steps to the cave where Bodhidharma meditated. Afterward he studied exercise physiology at Stanford. He explains why his master compared cardiovascular fitness to a lake returning to calm after a storm, and why he considers heart rate recovery perhaps the best marker of cardiovascular health, even better than VO2 max. Gjergja describes how the Zing AI coach is guardrailed by tens of thousands of rules and combines long-term trends and goals with real-time data like sleep and heart rate variability (HRV). It also uses computer vision to assess mobility and injury risk, and tracks body composition instead of scale weight. He talks about Zing’s partnerships with gym chains, health insurers, pharmaceutical companies, and Paris Saint-Germain, and about a co-pilot tool for personal trainers. Koenig and Gjergja also discuss functional and hybrid training, orthosomnia and sleep anxiety, data anxiety from wearables, and LDL cholesterol and Lp(a) in context. Koenig shares how his training helped him spot Lyme exposure early, and how his sprint coach Garnet Cross shaped his view of coaching, mindfulness, and consciousness. #TheDNAofThings #HeartRateRecovery #AIFitness #CardiovascularHealth #Shaolin LINKS: https://www.drjeremykoenig.com/ https://www.instagram.com/drjeremykoenig/ https://www.youtube.com/@drjeremykoenig
