On this episode of All About Fitness, Dr. Kelly McGonigal, a research psychologist at Stanford University, joins me to discuss her new book the Joy of Movement. Dr. McGonigal studies how physical activity and exercise can change the way your brain functions and our conversation will provide you with specific suggestions for how you can change your approach to exercise so that it can become something that you look forward to doing as opposed to being something that you feel you have to do.
