Doherty, who hit the headlines in Channel 4 documentary series Big Fat Gypsy Weddings, has apparently lost over 10lbs at a bootcamp in preparation for the keep-fit launch.
According to the Daily Star, Doherty used to regularly have 25 pints a day, but has now curbed his passion for alcohol.
He is also apparently considering teaming up with his Celebrity Big Brother co-star Sally Bercow for the project.
"It would be good to do something that couples can work out together to," Doherty told the newspaper. "There is nothing out there for a man and his woman to do together. I'm not sure about wearing any of that Lycra nonsense, though."
A rep for Doherty added: "He would love to film a fitness video for couples, so watch this space."
