Final answer:
Back pain relief can be achieved through strengthening or stretching the abdominal muscles, which are part of the core system supporting the spine and maintaining posture.
Step-by-step explanation:
Back pain can be relieved from either strengthening the abdominal muscles or stretching the abdominal muscles.
Strengthening or stretching the abdominal muscles can greatly contribute to back pain relief. The abdominal muscles, including the rectus abdominis, external oblique, internal oblique, and transversus abdominis, are part of the core that supports the spine. These muscles work in unison to maintain posture and balance. Strengthening exercises make these muscles more robust, while stretching promotes flexibility, both of which are vital to support the spinal structures and reduce stress on the back.
Additionally, a well-balanced core includes the muscles of the lower back like the quadratus lumborum, which also assist in maintaining proper posture and stability. Proper posture controlled by these muscles can prevent muscle fatigue and ensure that no single muscle group is overworked.
