“Want to know how I was able to get into top shape when I received the Lifetime Achievement Award from Arnold Schwarzenegger and transformed my life through fitness?” asks David Lyons, a man diagnosed with Multiple Sclerosis at the age of 47, and then, fighting all odds, rose from the depths of despair to a bodybuilding contest stage.
Born and raised in the vibrant, grit-filled streets of the Bronx and Queens, New York, David’s foundation was built on discipline and tenacity. This drive led him to enlist in the U.S. Marine Corps, where the rigorous training at Parris Island sharpened his resolve. Upon returning to civilian life, he initially pursued a path in film and television production at the New York Institute of Technology. “However, my true calling wasn’t behind a camera—it was in the arena of fitness.” As a martial artist, boxer, and competitive bodybuilder, David’s deep-seated passion for fitness and total wellness eventually overtook his interest in media, shifting his trajectory toward the fitness industry.
No is a Detour, Not a Dead End
David’s career has been a testament to the idea that ‘no’ is often just a detour, not a dead end. The early 1980s served as his first major professional ‘down.’ “I had a vision for my own gym, but faced the harsh reality of the financial world; with no formal business background, securing funding from banks or private investors proved nearly impossible.” Rather than retreating, David pivoted to strengthen his credentials, earning a B.S. in Nutrition while working on the gym floor at the Jack LaLanne chain.
The ultimate ‘up’ came through sheer persistence and performance. While working as a salesman at a new facility in Queens, David rapidly climbed the ranks to General Manager. His dedication caught the eye of the owner, who was pivoting his time into his real estate business and offered David the chance of a lifetime: the opportunity to buy the business. “That single location became the catalyst for my dream, eventually allowing me to own and operate multiple successful gym locations across the United States.”
Creating a Global Platform Through His Adversity
Today, David serves as the Founder and Director of OptimalBody Fitness and the MS Fitness Challenge charity. While his early career was focused on general physical excellence, the ‘Aha!’ moment that redefined his life’s work came in 2006. “That was the year I received a diagnosis of Multiple Sclerosis.”
In that moment of personal crisis, David realized there was a massive void in the fitness industry for those living with chronic conditions. Many felt abandoned by traditional fitness models or were told to ‘take it easy.’ He saw a desperate need for an advocate who understood the unique physiological challenges of MS but refused to accept physical decline as an inevitability.
This led to the birth of the MS Fitness Challenge—a charity founded by David and his wife, Kendra, to provide vital resources to those fighting the disease—and OptimalBody Fitness, the professional framework helping people reclaim their lives from the inside out.
The Passion of an Underdog
David’s passion is fueled by the transformation of the ‘underdog.’ There is no greater reward than seeing a person who felt defeated by a medical diagnosis realize they still have a voice, a choice, and a body that can perform. “I am driven by the responsibility of leadership and the desire to leave a legacy that proves physical limitations do not define the human spirit. Every life reached through the MS Fitness Challenge and OptimalBody program is a reminder of why I started this journey.”
When it comes to business, David describes himself as a calculated risk-taker. “I don’t believe in jumping blindly, but I also refuse to be paralyzed by the status quo. For a risk to be worth it, the reward must offer a significant impact on the lives of others.”
David built a career by going where others said he couldn’t. “When I was told a kid from the Bronx without a business degree couldn’t own a gym, I did it anyway. When I was told that an MS diagnosis meant the end of my fitness career, I built a global movement instead. My appetite for business is driven by the word ‘impossible’—if a risk has the potential to break new ground for the chronic disease community, I am all in.”
Democratizing Specialized Fitness on a Global Scale
However, David’s real test came during COVID-19. Before the pandemic, his mission was largely mobile; he traveled across the U.S., hosting live events at gyms to train both MS warriors and the fitness professionals who wanted to support them. “When the world shut down, my physical reach was instantly severed.” However, what appeared to be a catastrophic roadblock became the greatest accelerator of his mission.
David recalls, “COVID-19 forced us to pivot entirely to a digital landscape. We took our education and training modules online, birthing the global version of OptimalBody Fitness.” The result was staggering. By removing the barriers of travel and physical location, their charity and business exploded. They expanded their reach to 25 countries, “Impacting tens of thousands of lives that we never would have touched through physical events alone. We didn’t just survive the pandemic; we used it to democratize specialized fitness on a global scale.”
The Owner of a ‘Triple A’ Personality
Throughout his journey, David’s greatest strength is his relentless ‘Triple A’ personality. “That high-octane drive is what allowed me to scale businesses and reach 25 countries. However, that same strength is also my greatest ‘learning playground.”
For years, David has struggled with the art of slowing down. His brain and body are constantly in ‘overdrive’ mode, and learning to shut it off effectively has been a challenge. He has had to learn that while his drive builds the vision, he must be intentional about rest and trusting that he is still moving forward during a break. It is a work in progress, but it serves as a reminder to other leaders that even the strongest engines need a pit stop to avoid burnout, he smiles.
Fighting for the Balance Every Single Day
Moreover, managing a global fitness brand and an international charity is demanding, but doing so while living with Multiple Sclerosis adds a layer of complexity that most don’t see. “My secret to balance isn’t found in ‘slowing down,’ but in the precision of my lifestyle,” reveals David, who is a living laboratory for his own program; “I manage my symptoms by strictly adhering to the OptimalBody-OptimalMind system.”
Physically, he fuels his body with a rigorous anti-inflammatory diet to keep the ‘internal fire’ of MS at bay. Mentally and spiritually, he maintains a mindset rooted in the belief that his weaknesses are simply platforms for God’s strength to be revealed. By focusing on what he can control—his nutrition, his training, and his faith—the external challenges of business become secondary. “I don’t just teach this balance; I have to fight for it every single day.”
An Advice of Integrity
David’s advice to other aspirants taking on leadership roles in their respective fields is as solid as his mind and body: “If I could distill leadership down to one essential trait, it is ‘Integrity.” In today’s fast-paced, digital-first world, it is easy to ‘fake’ success or cut corners for a quick win. But without integrity, success is hollow and unsustainable.
To lead others, you must first lead yourself with honesty. People will follow your talent for a while, but they will stay for your character. Whether you are in a boardroom or on a gym floor, your word must be your bond. Build your foundation on truth, and the success that follows will actually mean something.
Finally, to the readers, David’s message is simple: never let your circumstances dictate your potential. True growth happens when you stop viewing obstacles as stop signs and start seeing them as stepping stones. Focus on integrity, prioritize your wellness, and stay disciplined in your faith. David’s life is proof that what was meant to defeat you can actually define you. You aren’t a product of your adversities; you are a product of God’s faithfulness and your own resilience.
A Journey from the Streets to the National Fitness Hall of Fame
Life will try to break you—that is a guarantee. But through his journey from the streets of NY to the National Fitness Hall of Fame, David has learned that “The very things meant to destroy us are often the building blocks of our greatest successes.” Don’t fear the adversity; embrace the refinement. Stay faithful, stay disciplined, and remember that your diagnosis or your background is not your destiny.
For those who want to see this path in action, David’s documentary, MS Fitness Challenge: The Journey, tells the full story of his rise from the initial diagnosis to founding the charity and being inducted into the National Fitness Hall of Fame. It’s a journey from adversity to victory that he hopes inspires everyone to keep moving forward. (Watch it here: https://optimalbodyfitness.vhx.tv/).
