Personal trainer Robert Fletcher claims that he created a show called "America's Next Great Trainer" and shopped it around Hollywood two years ago, reported TMZ.
Fletcher alleges he sent his pitch material to Stallone's publicist, and also to agents at William Morris Endeavor, which represent the 69-year-old actor.
The New York native says in court documents filed on June 10 that he even had a signed agreement with California-based conditioning coach Todd Durkin to host the show.
However, in 2015 Durkin stopped all communication with Fletcher. Fletcher also claims he sent "The Biggest Loser" producer David Broome marketing materials for the show.
The show features 20 male and female trainers as they compete in martial arts, strength training and boxing - which Fletcher claims is an exact copy of his idea for America's "Next Great Trainer".
The personal trainer is suing the "Creed" star, NBC, Durkin, and other Strong producers for upwards of USD 7 million.
