Wynonna has been working with her own personal trainer, Dominick, for several years, but this is the first time he's seen her really try to change her life.
"I have [noticed a change in her commitment], and it's only because of this show," Dominick said. "I've been with her for three years, and it was always like, 'How can I get her to commit to this workout?' She's always giving to everybody else all day long. We have a set workout, but I'm always the first to get cancelled. I know in her heart, she wants this."
