The hosts share practical exercise modifications, discuss the importance of reaching muscular failure, and emphasize recovery, nutrition, and consistency. They encourage listeners, especially women and older adults, to prioritize strength training for muscle growth for lifelong optimal health and independence, offering accessible strategies and resources for getting started at home.VivoBarefoot Discount:Support your feet and ankles with VivoBarefoot shoes—with perfect styles for any occasion!
