Limited flexibility in the lower back and thighs is often linked to back pain because it can contribute to muscle strain and mechanical stress on the lumbar region. When muscles in the lower back or the hamstrings (thighs) are tight, they can restrict the natural range of motion of the spine and pelvis, forcing the back to compensate in ways that may lead to injury or chronic discomfort.1

While lumbago is a general term for lower back pain, it is frequently associated with weak or strained muscles. Maintaining physical fitness through targeted movement is essential for spinal health; incorporating flexibility training alongside strength-building exercises helps ensure that muscles remain supple enough to support the spine without excessive tension. If you are experiencing persistent pain, it is important to address the underlying cause, as it may stem from conditions such as a herniated disk or sciatica rather than simple tightness.1
