The decision to go in a new direction with the show’s trainer is part of an overall reboot. “We intentionally tried to not replace Jillian,” executive producer Todd Lubin tells the publication.

Next season the show will be “getting slightly away from just the tape measure, and getting into overall well being and health,” says Lubin. “That’s where Loser needs to go.”

As for the 29-year-old Russian athlete, Lubin says her background makes her the right person to help motivate overweight contestants to push themselves.
