Heidi Montag 'Back on Workout Wagon'
Now that she's stuffed with turkey, Heidi Montag is hitting the gym.
"Back on the workout wagon! Too much Tgiving food!" Montag wrote on Twitter Thursday.
"Today was my first day back and I already feel so good! I am going to stick with it," Montag declared.
A few minutes later, she added, "I am determind to keep this up through the new year !! you guys are great motivators!"
Montag knows how to whip herself into shape.
She used her "Heidi Montag Workout" to slim down for her Miss Universe performance earlier this year.
