Your abs are part of your core, which includes your pelvic muscles, hips and the muscles that support the spine. The benefits of abs extend to daily function, sports performance and physical health. Strong abs help prevent an exaggerated anterior tilt to the pelvis. If you have this pelvic tilt, you may experience too much pressure on the lower back's discs and facet joints, flexible points that enable your back to bend. This pressure often leads to weakness, pain and potential rupture. ~ Berceste
