RTF# 232 Muscle After 40: Why Building Muscle Is Essential for Healthy Aging & Longevity
Let’s get into it! Some topics from today’s episode include:
⭐️Muscle is about longevity, not just looking “fit”
⭐️The three types of muscle: skeletal, cardiac, and smooth
⭐️Why muscle is called the “organ of longevity” by regulating glucose, insulin sensitivity, and metabolic health
⭐️The difference between strength, muscle mass, and muscle endurance
⭐️Sarcopenia, age-related muscle loss, affects function over time
⭐️Repeated dieting without resistance training can leave you under-muscled
⭐️How strength training can help with joint pain, arthritis, balance, and independence and why progressive overload matters more than just sweating or getting tired
⭐️Cardio, Pilates, yoga, and classes can be useful without replacing strength training
⭐️It is never too late to build muscle in your 40s, 50s, 60s, 70s, and beyond
