Last year, I had Sean Mulroney on the show, and he shared his story about how he lost over 100 pounds and got started with his personal trainer. So I thought it might be a good idea to get one of his personal trainers on the show to get her perspective on how she helped Sean and what were the challenges that she faced while training Sean.  Jamie Gilliam is an MS in exercise science. She has worked very closely with Sean and personally trained him physically to become more physically active.
