When reference is made to your “core” many people think it is your entire abdominal/trunk region. It actually refers to a specific group of deep muscles in your trunk region. The core muscles include the deepest layer of abdominals (the Transverse Abdominis), muscles of the pelvic floor, deep back muscles (Multifidi) and your Diaphragm (responsible for breathing).
Our “core” is responsible for stability with movement. These muscles work together to provide support for the trunk and spine. They are activated when we lift, lean, walk and with transitional movements (rising from sitting to standing). A lack of core strength can be associated with back, hip and pelvic pain and instability.
