Muscle is one of the most powerful and most underestimated predictors of long-term health. Beyond appearance or athletic performance, skeletal muscle plays a direct role in metabolic function, insulin sensitivity, cardiovascular health, cognitive protection, and lifespan. This playlist covers the science of muscle mass and strength — how they decline with age, why that decline matters clinically, and the evidence-based strategies for building and preserving them throughout life. Topics include resistance training, VO2 max, zone 2 cardio, visceral fat, body composition, and the physiological relationship between physical fitness and longevity.

Burnout, anxiety, chronic stress and exhaustion are not “mindset problems”... they’re measurable changes in your biology. In this video I break down what burnout really is in medical terms, and what people who never burn out do differently using The 1% Health Rule. I’m Dr Alex Wibberley, an A&E and Lifestyle Medicine doctor. After nearly a decade on the emergency department frontline, I’ve seen that people don’t suddenly “hit a wall” - their cortisol, blood sugar, nervous system and sleep rhythms have been failing quietly for years. In this video you’ll learn: • Why burnout is a physiological state, not just “feeling stressed” • The three silent biomarkers of burnout that show up before you feel tired • How rhythm, sleep, blood sugar and HRV shape your resilience • Why a lot of anxiety is metabolic, not mental • The simple daily micro-behaviours of people who stay sharp, calm and energised • The full 1% Health Rule blueprint you can start using today TIMESTAMPS 00:00 Intro 02:33 Chapter 1 - Burnout Isn't a Feeling (It's a Physiology) 06:25 Chapter 2 - The Compounding Health Curve: Why 1% Matters 10:29 Chapter 3 - The Three Silent Biomarkers of Burnout 15:01 Chapter 4 - Rhythm: The Real Secret of Energy That Never Crashes 19:14 Chapter 5 - Anxiety Isn't Mental (It's Metabolic) 23:14 Chapter 6 - The Recovery Gap: The Habit That Saves You From Burnout 27:40 Chapter 7 - Why Motivation Is a Terrible Health Strategy 31:15 Chapter 8 - Movement as Energy Regulation, Not Fitness 35:30 Chapter 9 - The Social Buffer: Why You Burn Out Faster Alone 39:45 Chapter 10 - The 1% Health Rule Blueprint 44:19 Thanks!
