A lean body in good shape and health is what many desire; and a flat tummy of course. Core muscles help you to stabilise, walk and maintain good posture. Weak core muscles have been linked to posture problems and back pain. Most people do not have a firm grasp of core muscles. Abs and the core are used synonymously by some.
However, abs are just one side of the core muscles. Having a flat tummy does not equate to core strength. Core muscles comprise the abs on the front, the gluteus and lower back, the diaphragm area, hip muscles and the pelvic floor. Fitness experts advise that core strength training is essential for overall fitness.
