Next comes hip openers, an important part of any mobility routine. The hips are one of the largest joints in the body, and they often become tight because of prolonged sitting or lack of movement. Tight hips can lead to discomfort in the lower back, knees, and even the legs. Hip-opening stretches improve flexibility, reduce stiffness, and make everyday activities like walking, bending, and exercising much more comfortable. They also help improve overall body movement and balance.
