🫀 About Jake Kelly, MD

I’m Dr. Jake Kelly — a board-certified performance cardiologist, VO₂ max, Metabolic & Longevity strategist, and Ironman triathlete on a mission to help people live 20+ more years they actually want.

Over the past two decades, I’ve trained as a physician, athlete, and educator — coaching elite endurance athletes, treating patients with advanced heart failure and cardiac transplant, and raising three resilient kids alongside my wife, Katie (a nurse practitioner, marathoner, and amazing chef).

Now I’m building a new model of care and content: one that blends medical precision with real-world performance.

🏃‍♂️ What This Newsletter Is About

Each week, I share science-backed, experience-tested insights on:

  • VO₂ Max and cardiorespiratory fitness (your real “vital sign”)

  • Metabolic health, insulin resistance, and energy

  • Mitochondria and muscle — the engines of long-term vitality

  • Training plans and protocols for real life

  • How I coach my family, patients, and readers toward better healthspan

This is not theory. It’s what we live and teach — from the clinic to the track to the dinner table.

🔬 Who This Is For
