Castronuova was also the head trainer on Season 11 of "The Biggest Loser", helping the show reach record high ratings.

She has been dedicated to fighting childhood obesity and started "Knockout Obesity Foundation" to help kids learn how to live a healthy life. Her programs incorporate Boxing, which she uses as an analogy to teach kids virtues like courage, fortitude and perseverance.

"My goal was always to use boxing as a parallel to illustrate to kids how results come from hard work and sacrifice," said Castronuova.
