A tight, inflexible spine affects posture, circulation, and even daily movement. This simple flexibility test isn’t just about stretching—it reflects how young and mobile your body truly is. Practice gentle back-opening stretches every day to reduce stiffness, improve posture, and help your body move with ease and confidence again. #backflexibility #spinehealth #posturema
