TED-Ed: What makes muscles grow? - Jeffrey Siegel

Muscles, making up a significant portion of body weight, require regular attention to grow or maintain. The brain and muscles work together to perform tasks, with muscle fibers undergoing stress-induced damage and repair, leading to growth. Hypertrophy requires exposure to higher workloads, while lack of resistance leads to atrophy. Nutrition, hormones, and rest are crucial for muscle repair and growth, with factors like gender, age, and genetics influencing muscle-building potential. Meaningful growth, akin to life, demands challenge and stress.
