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.

How much of your heart health is actually decided in one ordinary week, long before anything turns up as chest pain, a high blood pressure reading or a cholesterol result your GP wants to talk about? More than you would probably guess, and this video walks you through that week a day at a time, showing where brisk walking, strength training, the Mediterranean diet, sleep and your own numbers each fit into lowering your risk of a heart attack or a stroke as you get older. It is a seven day heart plan built around the things with real evidence behind them, so brisk walking, strength work you can do in your kitchen, blood pressure you measure properly at home, the Mediterranean diet trials, sleep, and the social connection nobody ever mentions at a health check. One job per day, and the research explained rather than glossed over. I have laid it out this way because heart advice tends to arrive all at once and leaves you with no idea where to start. Monday is your walk. Tuesday is putting muscle back on. Wednesday is the food shop rather than the willpower. Thursday is getting to know your own numbers. Friday is people. Saturday is the supplement cupboard and an honest look at what those bottles are doing. Sunday is sleep and twenty minutes of setting the week up. Heart disease builds silently inside the walls of your arteries across decades, so no seven days undo that. What a week can do is become the week you repeat, and that is where all of the power sits. The trials I go through here were run in people in their seventies and eighties, and the differences turned up within a couple of years, which is worth knowing if you have ever assumed it was too late to bother. What you'll learn: -What a flight of stairs tells you about your heart that a resting measurement cannot -How much walking actually protects your independence as you get older -Why losing muscle after fifty quietly pushes your blood sugar and blood pressure up -What the big Mediterranean diet trial found, and what it looked like day to day -How to take your blood pressure at home so the number is worth something -Why loneliness sits in the research next to smoking and blood pressure -What the largest fish oil and vitamin D trial actually showed Whether you want to bring your blood pressure down, keep doing your own shopping in twenty years, or simply give yourself the best chance of a long and active old age, you can start this today with a pair of shoes and a tin of beans.
