“Flexibility is overrated, just like good posture. Gymnasts and acrobats need it, the average person doesn’t. Most people need greater power and control throughout their existing range of motion: that’s much more useful for performance and injury prevention.
Another critical concept is that stiffness is a sensation, not a physical property. People think they need to be more flexible because they feel stiff, but that sensation is rarely related to actually limited range of motion. Stiffness is more like a kind of chronic pain, difficult to troubleshoot, much more complicated than range of motion.”
