The “core” really relates to all the muscles which provide stability during human movement. Although the abdominal are an important aspect if the core, it also includes deep hip, scapula, cervical, spinal and ankle stabilizers. often muscle can take multitask, either performing a stability and mobility role, such as the soleus, which not only produces ankle stability but generates a significant amount of movement across the ankle.
Good core stability programs should incorporate
Scapulo – thoracic stability
Central stability, including the abbs and diaphragm
Deep hip stability
ankle and knee stability
