This review article recognises the unique function of the core musculature. In many real life activities, these muscles act to stiffen the torso and function primarily to prevent motion. This is a fundamentally different function from those muscles of the limbs, which create motion. By stiffening the torso, power generated at the hips is transmitted more effectively by the core. Recognising this uniqueness, implications for exercise program design are discussed using progressions beginning with corrective and therapeutic exercises through stability/mobility, endurance, strength and power stages.
