In this episode of Everyday Health Stories, Dr. Reddy and Anna explore the groundbreaking science behind how exercise impacts aging at the genetic level. They discuss telomeres, the protective caps on our chromosomes that shorten over time, leading to aging and increased disease risk. But here’s the surprising part—not all exercise helps preserve telomeres. Dr. Reddy breaks down which exercises actually work, explaining why only high-intensity activities like running, HIIT, fast cycling, swimming, and rowing have been proven to extend telomere length and add years to your cellular health. Listeners will also learn about MET values and MET-minutes, how to measure exercise intensity effectively, and which common workout mistakes might be accelerating aging instead of preventing it. Whether you’re an athlete or just getting started, this episode provides practical, science-backed strategies to help you make every workout count!
