Lauren Bruzzone, 72, is true fitness inspiration.

The attorney and adjunct college professor regularly attends a 6 a.m. CrossFit class at a gym near her Stamford, Conn., home.

“This is not something I would have ever guessed I’d be doing if you asked me 15 years ago,” Bruzzone told “Good Morning America.” “[My friend] kind of had to talk me into it a little bit, but I figured I would try it and if I didn’t like it I would stop.”

“It’s just a little bit more intense but I’m still doing it and enjoying it,” she added.

Bruzzone’s definition of “just a little bit more intense” is debatable.

Carozza also credits Bruzzone’s strength in her 70s to her consistency as well as her willingness to focus on her weaknesses, instead of just doing the exercises at which she is best.

Bruzzone is also flexible, thanks to years of doing yoga, and watches her weight, though she doesn’t follow one particular diet.

Mostly, Bruzzone said she just follows the advice she would give to other people of any age, which is to never give up and to pace yourself with exercise.

“I’m happy taking it slow,” she said. “At my age you don’t want to break anything. It takes too long to fix.”
