“The Biggest Loser” will visit 2002 Olympic facilities in Utah on Tuesday night’s episode.
The contestants will train like Olympians and with Olympians.
Apolo Ohno, the most decorated U.S. Winter Olympian of all time, leads the cast of athletes scheduled to appear and is in the preview video above.
Also slated to join the show are bobsledders Lolo Jones and Jazmine Fenlator and curlers Debbie McCormick, Jessica Schultz and Ann Swisshelm.
The contestants will run more than a mile up a bobsled track, no easy task.
