Dr. John Ratey of Harvard Medical School presented findings that exercises incorporating complex motor movements create a sharper, more efficient brain. His research shows that as you challenge your body to perform complex physical movements, your brain releases growth factors that create new pathways between cells. Specifically, moves that challenge your balance (leg lifts with shoulder presses) or put you in out-of-the-ordinary positions (pretzel), activate these neurochemicals. Furthermore, these movements not only strengthen existing cells but trigger new cell growth. So the result? Better memory and attention skills and a rockin’ bod!
