One of the most common New Year’s resolutions is to lose weight and get in shape. But joining a gym or a spinning class can sometimes be intimidating and cost-prohibitive. In this week’s edition of Dr. Greg Davis on Medicine we revisit an in depth interview with Antonia Malchik, author of the best-selling book – A Walking Life: about the past and future of walking’s role in our shared humanity. She talks not only about the physical benefits of walking but also the mental and emotional boost we can get by lacing up our shoes and putting our best foot forward.
