In this Huberman Lab Essentials episode, I discuss how to build muscle strength and size (hypertrophy) and cover key training principles to enhance athletic performance and offset age-related muscle decline. I explain how the nervous system drives muscle movement, the key differences between training for hypertrophy or strength, and resistance training protocols to build muscle for performance and healthy aging. Additionally, I discuss tools for assessing recovery and the role of key nutrients—such as creatine and electrolytes—in supporting muscle development and performance. This episode provides actionable, science-backed strategies to enhance movement, preserve strength with age, and boost energy levels. Read the episode show notes at hubermanlab.com.
