The Seven Network is searching for ways to capitalise on the success of Australian Ninja Warrior with meetings being held to secure a similar format.

Nine Network's Australian Ninja Warrior has been the most successful television format of the year to date, smashing its primetime rivals Yummy Mummies and MasterChef. Despite its short season, the show's grand finale became the most watched non-sport program of 2017.

Now, creators of similar shows are circling the Seven Network to help them cash in on the current wave of interest in fitness-themed reality programs.

Industry sources said Seven is considering airing an Australian version of Spartan: Ultimate Team Challenge.
