Know More

Founder of Fluidity Rx

Michelle Austin, founder of Fluidity Rx, is a former Lotte Berk Method instructor who transformed the Barre fitness world by inventing the first free-standing, height-adjustable barre.

Since launching Fluidity, she’s sold over 500,000 units and watched the Barre category explode. As others rushed to capitalize, Michelle saw a surge of inferior equipment, subpar choreography, and confusion within the market.

Despite the noise, Michelle remained committed to one thing: improving outcomes—something she would never compromise on.

Now, with Fluidity Rx, Michelle has shifted her focus to merging her expertise in movement science with cutting-edge equipment design to partner with the medical industry.

Her goal: to help healthcare professionals improve patient outcomes with a smarter, more effective movement solution, Fluidity Rx.

Fluidity Rx Through The Years A Legacy of Innovation

1959

Lotte Berk Creates the Foundation

Lotte Berk, a Jewish-German ballerina who fled to London in 1935, teamed with an orthopedic surgeon to create the original exercise method using a wall-mounted bar—laying the foundation for what would become the "Barre" category in fitness

Training with Lotte

Michelle Austin trained under Lotte Berk in London, and later taught at the famed Madison Avenue studio in NYC. But over time, Michelle realized the method needed to evolve. It was creating dysfunction in her own body

her PHD Atomic Physicist father

Wanting a safer and more functional alternative, Michelle and her physicist father designed and built the first free-standing, height-adjustable device, allowing full 360° movement while supporting proper alignment.

Innovation Improving Outcomes

An MIT engineer—whom Michelle’s father described as the smartest mechanical engineer he had ever met—helped refine the design. Working together, they developed a height-adjustable device that supported full-body movement and alignment, with special attention to the often-overlooked back line. The prototype earned its first patent and went on to produce multiple additional patents and refinements.

Life Changing Results

Michelle recognized the harm in the traditional “pelvic tuck “used for Barre, which forced a posterior tilt, and instead championed a neutral pelvis to restore alignment. She developed a cueing system based on bony landmarks and designed balanced 360-degree choreography using the Fluidity Rx Stability Device. This helps users integrate all their muscles efficiently while in neutral alignment. The impact was profound, and she received heartfelt letters from people healing from incontinence, prolapse, back pain, balance issues, avoidance of surgery and so much more.

Expert Recognition

Meeting Dr. Cindy Neville, former head of the women’s health rehabilitation program at the world-renowned Rehabilitation Institute of Chicago, and widely recognized as one of the leading pelvic physical therapists in the world, changed everything. Dr. Neville immediately recognized the unique value of Fluidity and urged Michelle to introduce it into the rehabilitation field.

Global Excellence

The Rehabilitation Institute of Chicago—now known as the Shirley Ryan AbilityLab—is one of the most prestigious rehabilitation hospitals in the world. It has consistently been ranked the nation’s top rehab facility, renowned for combining cutting-edge research with exceptional patient care.

From Inventor to Patient

Michelle was diagnosed with a rare, aggressive form of uterine cancer that led to two major surgeries and chemotherapy. After her second surgery, a hysterectomy, she experienced an enterocele prolapse and significant pain. Realizing she needed a comprehensive recovery plan, she turned to skilled pelvic physical therapists, manual therapists, and Fluidity itself to fully heal.

Shared Healing, Deeper Resolve

Michelle’s own personal journey through cancer gave her a deeper understanding of the heartfelt letters she had received from clients, and confirmed that healing through alignment and integrative movement truly worked. It also strengthened her resolve to bring this kind of healing into the rehabilitation world.

Penn State Alumni Fellow Distinction

Dr. Karl Newell, former head of Kinesiology at Penn State, recognized Michelle had figured out how to scale function—what he called the “Holy Grail” of movement science. He would later honor her with Penn State’s highest recognition, the Alumni Fellow Award, which Michelle was deeply proud to receive.

Fluidity Rx is for everyone—men and women. It uses precise verbal instructions and movements in a neutral spine position—the optimal position for PFM contraction and relaxation—to activate the PFM and train both fast- and slow-twitch muscle fibers, maintaining the ideal proportion of each fiber type.

Get Fluidity Rx

Note: If you cannot engage your pelvic floor initially, it may take about two weeks of using the Ball Video, Standing Pelvic Floor Muscle Training Video, and Breath Video, three times a week, to progress to the Beginner, Intermediate, and Advanced Videos. This protocol is optimal for all types of pelvic floor dysfunction and both sexes.

Women with Stress Urinary Incontinence are 17 times more likely to heal if they strengthen their pelvic-floor muscles [1]
