Where Exactly Is Muscle Memory? And Other 'Movement In The News" Headlines

A deeper look into three recent headlines in the body-nerd world. First up, recent research has shown that our skeletal muscles remember training at the protein level - no brain required! This is exciting research and Katy and Jeannette discuss the implications for exercise over the lifespan. Second, they dig into a recent study of uphill walking; the research suggests it is cheaper to take the steeper route, but energy efficiency might not be the only consideration. Finally in response to the online noise about recent changes to the CDC developmental guidelines, Katy and Jeannette explain what has really changed and whether it should have caused such an upset.
