There's a gym in Chicago that lets people work out with their dogs.
The fitness center opened last year after the founder began exercising with her dog and lost 130 pounds. She says her late basset hound lost 22% of his body weight from their workouts together.
Members who work out at K9 Fit Club say exercising with their dogs absolutely keeps them motivated.
A second K9 Fit Club has since opened in Hinsdale, Illinois.
