Why Our Fitness Classes Work

We understand every client is unique. You have to shock your mind to change your body.  That’s why we customize every one of our fitness classes to fit specific needs.

Healthy weight loss and shaping your body is a possibility that is attainable for everyone! It has to do with food intake, movement and commitment. Our instructors do more than simply rotate you through the same clocked exercises, and they won’t damage your knees on a treadmill.

Each of our fitness classes is unique and keeps you engaged from beginning to end. We do not follow a checklist nor any choreography. Our instructors flow from move to move in order to balance HIIT, cardio and/or resistance training for real results. Our fitness abilities come from the original and most successful fitness program of all time, and Shellie leads a team of the most qualified instructors.

Whether it’s a one-on-one personal training or a group effort, we will do everything we can to help you achieve your goals and gain confidence through knowledge. It will be challenging, but it will be worth it. Let’s go!

About Our Fitness Center CEO/President

Shellie Blanks Cimarosti, World Fighting Champion and daughter of Tae Bo creator, recently launched her new brand, “Shell Shock Fitness®,” which combines HIIT, cardio kickboxing, strength training, standing bags and suspension training to provide real fitness results.

From her humble beginnings where she brought up in the projects of Erie, Pennsylvania, to her current residence just south of Nashville, Shellie is living her own version of a storybook fantasy. While living in Los Angeles, she trained the likes of Shaquille O’Neal, Robert Downey, Jr., Brooke Shields, Magic Johnson, Sugar Ray Leonard, Goldie Hawn, Jenny McCarthy, Bette Midler, Paula Abdul, Carmen Electra, Slash of Guns n’ Roses and Sinbad — just to name a few.

Shellie has quite the extensive resume. She starred as the original Yellow Power Ranger for fighting and stunt scenes. She modeled in a number of fitness magazines, starred in commercial campaigns and appeared on many TV spots such as “Oprah,” “Montell Williams” and “The Parkers.” She also has been featured in all of the Tae Bo videos, putting in plenty of time working toward her mastery of martial arts.

Her training began at the young age of 2 years old and at just 14, she won the Jiu Jitsu World Championships and a gold medal at the Junior Olympics for Full Contact Sparring. Currently, she is in a select club that only a few, dedicated women have attained, by acquiring a sixth-degree black belt in the martial art discipline of Tae Kwon Do.

Join Shellie and her team and become empowered to be the best version of yourself by tapping into the one thing necessary to achieve this common goal — your fire within. Sign up today.
