They say never trust a skinny chef, but we spotted several toques working up a sweat at the David Barton Gym at the Gansevoort South during the South Beach Wine & Food Festival. The number-one gym rat was Art Smith, who is best known as Oprah Winfrey's chef. The Chicagoan recently shed 100 pounds at the David Barton location in the Windy City, and he kept up his workout regiment here in Miami. It was a good thing he had such discipline because as one of the judges of the Burger Bash, Smith had to sample all 27 gourmet patties. How many miles on the treadmill did that take to burn off? Perennially perky Food Network star Rachael Ray was also addicted to the upscale gym. She and her rocker hubby, John Cusimano, went to the Collins Avenue sweat factory daily. In fact, one morning Ray arrived at the gym so early, it wasn't even open yet. No word on whether she shouted out "yum-o" during her cardio.
