Core fitness and core strengthening provide the cornerstones on which all fitness activities are based. Yet until a few year ago, core training was a well-kept secret known only to dancers and gymnasts, who were totally unaware the routines they’d been doing all their lives were about to go mainstream.
No one had been trying to keep core fitness a secret. Joseph Pilates had developed one formalized system of core training 100 years ago. But for the most part, the only people who had any interest in Pilates training were dancers who were trying to rehabilitate injuries. Other athletes trained with weights and did regular running routines to develop and maintain peak fitness. In the 1960s and 1970s, if you trained in a gym you went there to lift weights.
