"It is a quick workout, whether it's at home, at the gym or with a trainer, I usually do about 45 minutes of circuit training," Decker said.

The final staple of her routine: the South Beach Diet.

"I know I need protein and good fats and lots of veggies, but sometimes I get off track just like everyone else. Whenever I need a jumpstart or feel a plateau, I turn to South Beach Diet. I love that the program is delivered straight to my door and I always have South Beach shakes and snacks nearby for those grab-and-go moments," Decker said.
