Welcome back to Fat 2 Fab! Celebrity Fitness Trainer Shawnee Harkins -- from Dr. Phil's Ultimate Weight Loss Race -- whips SheWired's Senior Editor Tracy E. Gilchrist into shape in time for The Dinah!  We're not promising a bikini but Shawnee's going to make sure she can pull one off one if she wants.

This time on Fat 2 Fab, Shawnee takes Tracy for a "kick-your-ass" session hike up Runyon Canyon where she also grills her about her workout routine and teaches her some new moves.
