Enhancing Daily Functionality Through Cognition and Curiosity

In this episode, Regan Archibald explores the vital connection between your muscle, heart, and brain—what he calls the muscle-heart-brain axis—and why this triad is central to aging well. You’ll discover how muscle isn’t just for vanity, but a powerful organ system that communicates with your brain, boosts cardiovascular health, and secretes myokines that influence everything from immune function to glucose regulation. Regan shares powerful insights on peptides like MOTS-c, 5-Amino-1MQ, BPC-157, and GLP-1s, and how they enhance muscle recovery and metabolic health. He also introduces the "Fitness 50 Benchmarks," a diagnostic framework to help you measure and improve your performance with age. If you're looking for actionable ways to preserve cognitive sharpness, heart strength, and muscular vitality into your 80s, 90s, and beyond—this is the episode for you. www.agelessfuture.com
