If so, your low back and hips may be tight and lack flexibility. Back pain may soon be a problem. It s very important to have good flexibility in the spine, because excessive tightness in the spine can impede normal movement. Muscles weaken when movement is limited.
Flexibility allows muscles and joints to move through their full range of motion.
It is joint specific. This means that a person may have excellent range of motion in one joint and be limited in another. Poor flexibility of the back and hips may lead to stiffness, poor posture, back problems, movement limitations, and a higher risk for injury to muscles, tendons, and ligaments. With aging and inactivity comes less range of motion. What is unclear is how much of this reduction in joint flexibility is caused by aging or by the reduced physical activity related to aging.
