Exercise & FitnessScience-Backed Stretching Protocols to Build Flexibility at Any Age
In this Huberman Lab Essentials episode, Andrew Huberman explores the biology behind flexibility, covering the roles of muscle, connective tissue, and key neural structures like Golgi tendon organs and von Economo neurons in regulating range of motion. He compares four stretching types — dynamic, ballistic, static, and proprioceptive neuromuscular facilitation (PNF) — and clarifies which are most effective for different goals. A key focus is static stretching: Huberman recommends low-intensity, longer-duration holds using the 'micro-stretching' approach and the Anderson Method to improve flexibility without triggering protective reflexes. He also addresses whether to stretch before exercise, how warming up affects outcomes, and how aging accelerates flexibility loss. The episode closes with a discussion of how yoga may improve pain tolerance through insula-mediated pathways, offering insight into why consistent stretching has benefits well beyond physical range of motion.
