NBC has announced The Biggest Loser's tenth edition will premiere Tuesday, September 21 at 8PM ET/PT.

Similar to its last five editions, the reality weight-loss competition's tenth edition will consist of two-hour episodes throughout its broadcast run.

The Biggest Loser trainers Bob Harper and Jillian Michaels and host Alison Sweeney will all return for the new season.

NBC began casting for The Biggest Loser's tenth season in February via a 15-city casting tour which began in Chicago and concluded in Los Angeles.

In addition The Biggest Loser's tenth-season premiere, NBC also announced its non-celebrity revival of The Apprentice will premiere Thursday, September 23 at 10PM ET/PT.

The revival -- the first non-celebrity Trump edition of The Apprentice in three years and seventh overall -- will follow 16 new candidates as they enter the boardroom for the opportunity to land a job within The Trump Organization with a six-figure salary.
