Jennifer “JJ Dancer” Johnson’s journey into the world of performing arts began at the age of four. Born and raised in Chicago, she took her first steps into dance as a young child attending a school with ballet as a requirement. Her first audition experience was The Nutcracker and she was performing professionally by the age of eight, with wages going towards a college fund.

Her passion for physical expression was always undeniable, yet as she entered adulthood, she found herself questioning her path. Torn between different career options, she initially pursued a degree in psychology at HBCU Howard University, but a spot on the Washington Wizards NBA team brought her right back to dance.

As a rookie on the Wizards dance team, during a routine weight check-in, JJ was told she needed to lose 5 pounds. “I was shooketh!” she exclaimed as she described the ordeal in our sit-down interview. But, the experience got her in the gym, where she says she found her love for fitness…and found herself a job.

She was spending so much time at the gym that working there seemed like a natural next step. So, for a while, she was juggling the job at Bally Total Fitness with school, being on an NBA dance team, and touring as a professional dancer, and she was all in on performing at the highest levels.

Knowing career expansion was going to be in Los Angeles or New York City, JJ made the bold decision to move to LA in the early 2000’s with a determination to make an impression.

JJ’s first major gig was for ComicView, marking the beginning of a lucrative career in entertainment. She went on to appear in television and film and share stages with some of the biggest stars in the world, like Beyoncé Giselle Knowles-Carter and Jennifer Lopez.

Living in LA, JJ thrived in the fast paced entertainment industry, but like many in that space, she found herself caught in a cycle of highs and lows.

Fast forward, she goes to an audition for a celebrity fitness company that was looking for dancers to work as trainers, and she booked!

This was a pivotal moment that supported a smooth transition into fitness from the dance world. JJ enjoyed the work, and the pay, and had no intentions of going anywhere anytime soon, until the owner of the company told her that she was forbidden from doing moves that weren’t “method,” meaning moves outside of how she was trained.

JJ eventually realized she wanted more autonomy over her approach to training, so she took what she could from the experience to start something of her own.

She began building her own private training company under the name JJ Dancer, which quickly attracted high-profile clients due to its hush-hush nature.

Because she had just left a fitness company where she signed a non-compete before leaving, she took a more IYKYK (if you know you know) approach, but the secrecy attached to the classes only fueled its demand, and its success skyrocketed. Big names like Taylor Swift and Jessica Alba started popping up to classes, with Jessica Alba being such a fan of JJ that she often brought friends to class and eventually hired JJ to choreograph her for Sin City 2.

But with success came challenges, of course. JJ soon found herself in the midst of legal disputes as she fought to keep her business alive.

Then came 2020. The pandemic forced a shift for many, and for JJ, it became a moment of transformation. Having already decided to leave industry politics behind, she and her husband moved to Mexico just months before learning of a global shutdown.

While she knew she would lose a good bit of U.S. clientele by making the move, she maintained steady business in Asia. But as travel restrictions tightened, her clients in China, who were among the first affected, started pushing for virtual training.

“Most of my clients were in LA and Asia and China and whatnot, so now everybody’s going online. When I left LA, a lot of them were like, ‘Oh, JJ, I need you in person. Next time you come back we’ll train, or maybe I’ll come visit and we’ll train.’ The online thing was just not something that they wanted to do… Here comes the pandemic. Everybody’s online, and what do you know, I got my clients back.”

This pivot set the foundation for a new brand: Bangin’ Body Online.

Inspired from a previous conversation with a fellow trainer while filming for Cosmopolitan, JJ was moved to rebrand. “Part of the reasoning for the rebrand from JJ Dancer to Bangin’ Body, well, the main reason is I didn’t want it to be only about myself anymore. Bangin’ Body felt more, like, community vibe. It wasn’t so much about me, me, me, which was the LA mentality. When I’m in LA I’m JJ Dancer, whereas Bangin’ Body is us, us, us!”

She began filming online classes in rented Airbnbs, but soon realized she needed a dedicated space. This led to the opening of a fitness studio in Mérida, Mexico that has evolved into a thriving community hub, welcoming both locals and expats. Today, the studio is more than just a fitness space, actively participating in city-wide events and other philanthropic ventures.

Beyond fitness, JJ has been a dedicated vegan for over 15 years and remains deeply involved in the vegan community. She continues to offer both virtual and in-person one-on-one training while her studio hosts a variety of group classes.

Known for her incredible strength and commitment to movement, JJ’s presence is felt not just in the way she trains, but in the way she empowers others to take control of their health and wellness.

JJ is now gearing up for a fitness retreat in Croatia taking place September 20-27, 2026 alongside bodybuilder Shaun T.
