Effective stretching should be approached as a neurological process aimed at increasing the nervous system's tolerance to stretch, rather than as a simple mechanical deformation of tissues.

This perspective is widely supported by modern movement neuroscience. Research indicates that short- and medium-term increases in flexibility result more from a change in sensory tolerance to stretching (via nociceptors and Golgi tendon organs) than from permanent structural lengthening of muscle fibers (Meta-analysis: Weppler & Magnusson, 2010). The central nervous system acts as a 'guardrail' by limiting range of motion to protect joint integrity. Andrew Huberman's approach is therefore scientifically sound and aligns with the concept of 'stretch tolerance.' It is worth noting, however, that over the long term, adaptive changes in connective tissues may also occur, although the neurological mechanism is the dominant factor during individual sessions. This is a view that intelligently shifts the focus from 'physical strain' to 'neural regulation.'
