Cara Castronuova was born in 1979.  Raised in Elmont, New York, with three younger brothers. Her father, a former Marine led her to boxing at the age of five in the family garage.  An athlete at an early age, she wrestled in high school and in college. Cara graduated from Hofstra University with a Bachelor of Arts degree in communications.

Castronuova first entered the boxing arena as a youth boxing trainer, and shortly after, began competing locally as a boxer, winning her first fight in 2002 at the NY Empire State Games in Syracuse. She also did volunteer work for a

government-funded program for troubled youth to

teach them the virtues of boxing and keep them off the


While working as a personal fitness and boxing trainer

at popular sports clubs like Chelsea Piers and Gleason's

Boxing Gym, she used fighting and boxing to encourage

clients to "find their warrior within."

Castronuova won a pair of "Silver Gloves" in 2004, the

second-place prize in the Golden Gloves competition, all

while continuing to train clients. 

Castronuova came back one year later and won her first

New York Golden Gloves championship at Madison

Square Garden in 2005 in front of a televised, capacity crowd.

Her beloved father, who suffered from obesity, passed away when she was 14. This was a tragic blow for Cara. "I wish I could help him now, knowing what I know," Cara says.

After losing her father, Cara and her family banded together to become  stronger through the loss, only to be struck by tragedy again when Cara's mother was killed in a car accident in 2006.

While working working in various boxing gyms in New York and boxing competitively she submitted an audition tape to the hit television show “The Biggest Loser”  Cara was ultimately selected from trainers from around the world to join Jillian Micheals and Bob Harper as one of two of the new Mystery trainers on the show.

"It was a whirlwind process. My background as a fighter has played an important role in landing this job and in ultimately getting the weight off the contestants," says Cara.

"I am here to teach the contestants to have the heart, and mindset, of a fighter. They have been getting knocked down their whole lives. I am here to help them realize that their lives are worth fighting for," says Cara. "It's time to get back up off 'the canvas' and start fighting again."

"I feel like my experience as a fighter inside the ring and out is what makes me an outstanding trainer as I am able to understand the hardships the contestants have experienced and push them to get back up again," Cara says. "A fighter gets back up, no matter what."

In addition to her turns in the ring and her new television exposure, Cara has a budding film career. Appearing in seven feature films since 2007.
