Carla Birnberg


Carla Birnberg, AKA MizFIt, is an award winning writer, community builder, personal trainer, and bodybuilding competitor.

A blogger since 2001, she launched MizFitOnline in 2007 to share her health and fitness knowledge with those who might not have access to one-on-one training.
As a result of her online personality and background in counseling, Carla has gained attention of publications like Women's Day, Experience Life,, Glamour, Women's Health, Fitness, Yahoo!, Yahoo!Shine, Yahoo!’s YourWisdom, Runners World, and Austin FIT magazine.

She was also profiled in Susan Getgood’s book: Professional Blogging For Dummies.

Carla was identified by as one of ten individuals who exemplify the ability to create a strong personal brand, named as one of Five Favorite Fitness Blogs by Athleta® brand and voted one of the Top Five Fitness Blogs by Shape Magazine®.

She was chosen by Eyeopener TV as the blogger to launch their Blogger of the Week segment, by FitFluential to serve as their first Ambassador Spotlight and named a Transform Your Workout fitness expert by Café Mom alongside BRAVO TV’s Jackie Warner and The Biggest Loser’s Alison Sweeney.

Carla serves as fitness expert and regular guest on Mom Talk Radio and Dr.Fitness & the Fat Guy.

Most recently she was voted one of Austin’s Fittest Moms, selected People’s Choice in the Fila Real Women model casting call and chosen to be one of the first group of Fitfluential ambassadors.

In her spare time, she juggles fulltime motherhood, filming motivational/exercise videos, crafting irreverent tweets, recording a biweekly podcast all without breaking a sweat....and, when she does, she simply calls it cardio.

Her health motto (& life motto) is …fitness isn’t about fitting in.

She believes we may all have the shared goal of living a longer, healthier, more vibrant life but it’s ok (& even encouraged) to carve our own unique path to get there.
