@bullfitnesshq: Adjustable posture alignment aid designed to provide passive thoracic extension and scapular retraction through controlled external positioning of the shoulders and upper spine. By mechanically cueing upright posture and facilitating gentle stretching of the pectoral, cervical, and upper thoracic musculature, the device may increase postural awareness and temporarily reduce flexion-dominant positioning associated with prolonged sitting. Intended for low-intensity mobility support and proprioceptive feedback rather than structural correction or medical treatment. #posture #stretching #backpain #postureexercises #healthyneckposture
