After 40, Your Muscles Change—Here's What Science Says

A conversation with Professor Leigh Breen, an expert in translational muscle physiology, about why muscle strength is crucial for healthy ageing and longevity. We explore why skeletal muscle is now considered our largest organ, the science behind age-related muscle loss (sarcopenia), and practical strength training approaches for people of all ages and abilities. Discover how resistance training, combined with proper nutrition, can dramatically improve your health span and help you maintain independence as you age.
