![]() This we accomplish by training rotational movements. As more research is published, the link between your core and low back pain is astounding and definite. Physical therapist, Sahrmann, states, “ during most daily activities, the primary role of the abdominal muscles is to provide isometric support and limit the degree of rotation of the trunk…A large percentage of low back problems occur because the abdominal muscles are not maintaining tight control over the rotation between the pelvis and the spine at the L5- S1 level.” Basically, we need a stronger core to counteract rotational forces – our body turning. The reasoning behind this shift in core emphasis vs the abs is the ever increasing incidence of low back pain. However, also be prepared for some back pain down the road! Sure, if you just want to stand in the mirror and flex your six pack – go right ahead and crunch. Because of this, your core is so much more important than your abs. ![]() ![]() This area works together to keep you upright, to resist motion so you don’t fall over, to bend over AND stand back up again, to rotate, to walk/run efficiently, etc. The ENTIRE middle of your body is your core. Whereas, your CORE is a much bigger area! Your core covers the area from the rib cage down to your glutes on all sides of your body and incorporates your back muscles. Beyond that, they’re not so functional in daily tasks that require you to do more than bend over (because you have to stand back up again, right?). They’re the muscles that make up the front & side area of your belly (for lack of a better word). The long sought after six-pack is more about clean eating than doing a zillion crunches or sit ups. Your abs are just your abs. ![]() Now we know that the core functions more to help anti-rotation (twisting) of the trunk vs flexion of the trunk (crunching). The gold standard ab exercise used to be crunches, but then came the concept of the core. Someone asked why we don’t do any crunches or sit ups in class anymore. ![]()
