QHS Alumni Spotlight: Dan Isaacson ’67

How a QHS Alum Became a Hollywood Trainer to the Stars

By: Katie Rodemich ’02

From North 12th Street to soundstages in Hollywood, Dan Isaacson’s journey has been anything but typical—but its foundation was unmistakably Quincy. As a proud graduate of the QHS Class of 1967, Dan’s life has spanned from pony shows, football games, groundbreaking fitness studios, and collaborations with some of Hollywood’s biggest names. He helped pioneer the personal training movement yet credits his start to a tenor sax solo in the QHS band and the hard-earned lessons of growing up in a close-knit Midwest town.

“My father was owner of John Isaacson and Sons Trucking, that taught me the value of work, family, community, and a great respect for Quincy’s historic heritage,” Dan said, reflecting on his upbringing.

Dan was raised in north Quincy, where he and his siblings shared a big farmhouse without indoor plumbing with 20 acres of cornfield between his house and the original Chatten Orchards! He loves to remember eating apples, riding ponies to the neighbors’ house and showing Hackney ponies at the Illinois State Fair. He attended Highland Elementary School for 1^st grade and then it became Highland- Riverside Elementary School which was part of one of the first integrated student groups in the area—a formative experience that taught him early lessons about the importance of diversity, equity, community, and value of friends and school connections.

At Quincy Senior High School, Dan was a well-rounded and dynamic student: a football player, played the tenor saxophone and a student leader. He was named Most Improved Player on the 1966–67 football team and still vividly remembers the moment he stepped into the spotlight at Quincy Junior High School to perform a tenor sax solo.

“My courage was stretched in junior high when I had to stand and perform a tenor sax solo to Night Train in front of two thousand students,” he recalls. “It was a James Brown hit at the time! If you listen to the 1962 version of the solo, you’ll hear exactly how James Brown does it best!”

Dan credits much of his early inspiration to his British Literature teacher, Marjorie Bolt, whose love for the British and guidance left a lasting impression. He also reflects fondly on the values he gained from the classroom and the locker room alike—especially the lessons in discipline, resilience, and respect instilled by outstanding coaches like Bill Gross, Dale Hendren, Bill Strickland, and others.

“One of the best times,” he adds, “was always watching Coach Sherrill Hanks and all my friends on the basketball team almost make it to Champaign in 1967!”

After earning his Bachelor of Science in Recreation and Park Administration from Western Illinois University in 1971, Dan went on to complete a master’s degree in the same field at the University of Illinois Urbana-Champaign in 1972. It was during those formative years at WIU—grounded in Midwestern values and a sense of purpose—that he first envisioned a career centered on helping others transform their lives.

“Dr. Tony Mobley at Western really saved my life,” Dan said. “I had started in accounting and business, but it just was not the path I wanted to follow. After my first quarter, I interviewed other departments on campus and met Dr. Tony Mobley—he was launching the Recreation and Park Administration program. I became completely immersed in it and eventually earned a graduate degree in the field. I was on track to do some big things. I had dreams of leading the National Park Service—never quite made it there—but Dr. Mobley went on to become the longest-serving dean Indiana University ever had. And truly, he’s one of the nicest, kindest people I’ve ever known.”

Before Dan Isaacson became Hollywood’s go-to expert for performance transformation, his path took a turn few recent grad school students would dare. He turned down a prestigious, personal invitation from Dr. Mobley to join the Department at Western Illinois University and pursue a Ph.D. Instead, in 1972–73, Dan set off across Europe by train—traveling to 13 countries, including Morocco.

He walked through Checkpoint Charlie, went behind the Iron Curtain at the Berlin Wall, toured Olympic complexes in Munich and Innsbruck, witnessed a bullfight in Madrid on Christmas Day, and stood in the Vatican on New Year’s Day—just as the Pope delivered a special New Year’s blessing to the crowd.

Dan’s guiding philosophy?
“I don’t want to look back on my life one day and say, ‘I wish I would’ve done that.’”

Dan’s first professional role was as the inaugural manager of the Sheridan Swim Club. Under his leadership, the club expanded its facilities by adding tennis courts and became the home base for the new Quincy High School Swim Team. It quickly developed a competitive age-group program, producing several QHS graduates who earned the school’s first collegiate swim scholarships.

Sheridan was also an early training ground for Olympic hopefuls—including Nicole Kramer ‘80, who trained there before heading to Mission Viejo, Calif., and eventually competing in the 1976 Montreal Olympics. During those Games, Dan served as Quincy’s voice on the ground, reporting live for WGEM alongside Chuck Brady, sports editor of the Quincy Herald-Whig.

Dan also partnered with the Western Illinois University Swim and Diving Coach to launch the first men’s swim testing program at Sheridan for fitness training, working with Dr. Paul Hutinger. Dr. Hutinger was a pioneer in adult fitness swimming and developed one of the first such programs in the U.S. This innovation came at the dawn of the modern fitness movement—spurred by Dr. Kenneth Cooper’s groundbreaking Aerobics book in the late 1960s. Sheridan Swim Club, in turn, became part of that early wave of America’s fitness boom.

From there, Dan moved west to manage programs at elite, full-service athletic clubs that were pioneering a new wave of real estate-driven fitness centers in cities like Denver, Las Vegas, Washington, D.C., and Newport Beach. These clubs catered to high-profile clientele and helped lay the foundation for what would become a national fitness boom.

In Denver, Dan helped establish one of the first privately owned fitness clubs—an early model for what we now know as Equinox, LA Fitness, Anytime Fitness, Planet Fitness, and 24-Hour Fitness. During this time, he led running and fitness seminars with former Olympians, created the “Hustler of the Week” Awards in partnership with the Denver Broncos, and became a co-owner of the International Athletic Club.

There, he hosted the Denver Fight Weigh-In for Muhammad Ali, who fought one of his first exhibition matches post-retirement at Mile High Stadium.

These roles became the proving ground where Dan refined his core philosophy: that fitness is about unlocking the best version of a person—not just physically, but mentally, emotionally, and professionally.

Then, in 1982, Hollywood called. Dan launched his own company, and he and his wife Kim moved to Aspen, Colo., where he became the Athletic Consultant for the new Snowmass Club. It was there, during a summer play in Snowmass titled Mass Appeal, that he met John Travolta.

John Travolta, already a global icon from Saturday Night Fever and Grease, had signed on to reprise his role as Tony Manero in the film Staying Alive. This time, the character was no longer a disco-loving dreamer—he was a Broadway-level dancer, and Travolta would need to deliver a performance that was athletic, precise, and visually striking.

At the time, actors typically prepped for roles with general workouts—or not at all. There was no blueprint for role-specific physical transformation. But Dan saw what others didn’t: an opportunity to rewrite the rules of film preparation. He approached the task as a scientist, coach, and storyteller all in one.

John Travolta didn’t just need to look like a dancer—he needed to move with the precision and presence of someone who had trained professionally for years. Dan focused on developing muscle endurance, strength and a dancer’s physique, body awareness, and discipline, all within a strict timeline to meet the demands of the production.

Dan developed a customized, science-based training program that not only reshaped Travolta’s physique to resemble that of professional dancer, Rudolf Nureyev, but also demonstrated how strategic fitness could elevate on-screen performance. The transformation was striking—and the impact immediate. It helped usher in a new cultural understanding of what actors could physically achieve with the right training, laying the groundwork for the modern personal training industry.

Dan, working with Director Sylvester Stallone and the film dance choreographers, created a highly structured program grounded in emerging sports science:

• Performance-based metrics to track measurable improvement
• Periodized strength training to sculpt lean muscle and support posture
• Mobility drills and flexibility routines to match a dancer’s grace
• Cardio conditioning that simulated the high-energy demands of the stage
• Nutrition protocols tailored to balance aesthetics and energy

What followed was a transformation that made headlines. Travolta’s chiseled physique and confident movement stunned audiences and critics alike. The press coverage wasn’t just about the movie—it was about the method. For the first time, a trainer was recognized as an integral part of the production process.

“Timing was everything. Honestly, I don’t think I’d be where I am today without Staying Alive. That film—and John’s transformation—played a huge role in shaping my path. If you look up Rudolf Nureyev, the legendary Russian dancer, and then watch John in Staying Alive—especially his upper body strength and movement—you’ll see exactly what we were going for. That was the look. That was the goal.

“People often forget that Sylvester Stallone directed that movie. I will always be grateful to John and his confidence in my work and thankful for the longtime friendship with me, my wife, Kim and our family! Likewise, my deepest thanks also go to Sly Stallone and his talent and creative genius as a visionary director who was always there with encouragement and direction during pre-production and shooting of the film!”

Travolta’s physical transformation for the role became a cultural turning point and helped launch what would become the modern personal training movement. This high-profile success led Dan to develop the first celebrity fitness training center and science-based training program for actors at Paramount Pictures.

This landmark success sparked a cultural shift. Suddenly, producers, directors, and talent agents began asking, “Who trained Travolta?” Studios realized that physical authenticity was no longer optional—it was expected.

As Dan’s influence in the entertainment industry grew, so did the depth of his relationships with clients—none more enduring than his 35-year collaboration with actor and comedian Billy Crystal. What began as training for specific roles evolved into a lifelong friendship. Dan supported Crystal through countless projects, from hosting the Academy Awards to his Tony Award-winning Broadway show 700 Sundays, tailoring performance-specific programs that honored both the physical and emotional demands of storytelling.

“Billy’s one of the most genuine, grounded people I’ve ever worked with,” Dan shares. “He brought laughter into every session, and we always supported each other on and off set.”

More than a trainer, Dan became a trusted confidant and extended member of the Crystal family. His legacy in Hollywood wasn’t built on quick fixes, but on trust, consistency, and a deep understanding of what it means to show up—for both the role and the person behind it.

Then came Tom Hanks.

When Hanks was cast in Philadelphia, he faced a daunting challenge: portraying a man in the final stages of AIDS with empathy and accuracy. The transformation required rapid yet controlled fat loss, muscle preservation, and emotional grounding.

Dan approached the project with clinical rigor. He assembled a support team that included physician consultation, dietitian, on stage specific food menus and chefs. Hanks’s weight loss was paced at exactly half a pound of fat per day, ensuring safety while achieving the visual and physical effect the role demanded.

It was one of the most exacting programs Dan had ever developed, but Tom remained steady. He understood the responsibility of that story. “Tom had incredible discipline,” Dan recalled. “Because the movie was shot in sequence—starting with the moment his character learns he’s contracted AIDS—the weight loss had to be progressive and believable.” From that point on, the transformation began. The 1,000 calories he ate during the day would be burned off at the end of the day running on the treadmill, climbing on the stair master and cycling on the Lifecyle.

Hanks would go on to win the Academy Award for Best Actor, and the film itself became a defining moment in cinematic history. By taking on this role, Tom showed the tragic effects of AIDS—bringing visibility to a terrible disease and, in the process, helping millions around the world.

Dan’s work didn’t stop at individual clients. He believed the entertainment industry needed a cultural infrastructure for wellness—one that empowered not just stars, but writers, crew, and creatives to show up at their best.

These projects solidified Dan’s reputation as a go-to expert in performance-focused fitness. His client roster quickly grew to include top-tier actors, musicians, and athletes—all drawn to his innovative techniques, results-driven mindset, and trusted discretion. His influence extended beyond the gym as he became the first Fitness Editor for Good Morning America and brought wellness insights to millions of viewers across the country. He co-starred in Jane Fonda’s Workout With Weights, a hit video that merged celebrity fitness with at-home accessibility. Recognizing the need for mobile services, he designed 40-foot training trailers that could travel to remote sets—from desert shoots to mountain scenes—bringing world-class wellness wherever it was needed.

Perhaps his most visionary achievement was designing the Sony Pictures Athletic Club—the first purpose-built wellness facility on a major Hollywood studio lot. More than just a gym, the club set a new standard for how the entertainment industry supported physical and mental well-being. It included: full-court basketball courts, indoor and outdoor training spaces, private recovery rooms, on-site coaching and nutrition suites.

It wasn’t just about aesthetics or amenities—it was about reimagining how wellness could be integrated into the everyday workflow of performers and professionals. Dan’s approach helped shape a new culture of health in Hollywood, one where preparation and recovery were treated with the same discipline as the performance itself.

Dan also designed science-based fitness programs tailored specifically to the needs of film and television actors, stage performers, and professional athletes. His career highlights include coordinating wellness programs for Columbia and TriStar Pictures, authoring The Equation, and being appointed Executive Director of the California Governor’s Council on Physical Fitness and Sports, chaired by Arnold Schwarzenegger.

His client list reads like a Hall of Fame: Christopher Reeve, Victoria Principal, Linda Evans, Indy Race Car Champion Danny Sullivan, Clint Black, Michael Keaton, Robin Williams, Jamie Lee Curtis, Johnny Depp, Ice Cube, Meg Ryan, Denzel Washington and many more—each trusting Dan with their craft, their bodies, and their personal journeys.

His training helped power unforgettable performances in Forrest Gump, Superman, Batman, Dallas, Dynasty, and more.

In 2024, Dan’s contributions were formally recognized with his induction into the National Fitness Hall of Fame—a milestone celebrating more than four decades of pioneering work in fitness, film, and human potential.

That unshakable sense of identity wasn’t shaped by experience alone—it was also forged by the people who believed in Dan and invested in his growth. Chief among them were Jack and Elaine LaLanne, close family friends and trusted mentors who exemplified the power of leading with both strength and compassion. Jack—widely known as the “Godfather of Fitness”—revolutionized the wellness industry with his 1950s TV show, groundbreaking exercise techniques, and tireless advocacy for nutrition and movement. But to Dan, he was more than a legend; he was someone who recognized his potential long before the headlines and accolades, and who encouraged him to pursue a path where service and wellness could go hand in hand.

Dan continues to honor the LaLanne legacy today, mentoring young professionals and carrying forward the values they instilled. In his latest venture—a podcast exploring the human stories behind performance, purpose, and growth—he draws from those early lessons. Whether he’s in conversation with fellow fitness pioneers, entertainers, or rising changemakers, Dan’s message remains grounded in what he learned from Jack, Elaine, and his Quincy roots: that real transformation is built on discipline, integrity, and care.

Today, Dan lives in Thousand Oaks, Calif., with his wife Kim—his partner in life and business. Together, they’ve built Isaacson Fitness LLC, a company rooted in science, heart, and real-world impact. Kim, a realtor with a strong strategic vision, has played a vital role in shaping every chapter of their shared journey. Their work spans film, television, and digital platforms, and now includes artificial intelligence applications in wellness and outreach through social media.

Their greatest pride, however, is family. Dan and Kim’s children, Eric and Kaila, and their grandchildren—Luke, Daniel, Michael and new baby Emma—represent the next generation of learners, leaders, and dreamers. Watching them grow, Dan sees the same love, values, and resilience that defined his own journey.

Whether training Oscar winners, guiding new voices, or sharing quiet moments with family, Dan Isaacson leads with the quiet strength he first discovered in Quincy—shaped by his parents, his teachers, close family friends and mentors like Jack and Elaine LaLanne, and other fitness pioneers who believed wellness could change lives.

Dan often reflects on how growing up in Quincy shaped his character, instilling in him a deep-rooted spirit of resilience and ingenuity.

“People forget that Quincy has produced pioneers,” he says. “We came from a place where you had to figure things out—and often, we were the first to do it.”

Though his career took off in Los Angeles, Dan’s heart has never strayed far from home.

“Quincy has always been a great Christmas town,” he says. He fondly remembers grabbing onion rings at The Patio and cheering on the Blue Devils at basketball games. He takes pride in Quincy’s legacy of innovation—from Floyd Baldwin’s parachute invention to Nicole Kramer’s appearance in the 1976 Olympics.

Beyond its people, Dan treasures the city’s deep roots and rich stories—historic homes lining Maine Street, riverfront legends, and generations of grit and grace passed down through the years. For Dan, that creative, can-do spirit—what he calls “Quincyness”—continues to guide him.

He often thinks back to the words his parents lived by. “Bloom where you’re planted,” his mother would say. From his father came the reassurance that stuck with him through every chapter: “You can always come back home.” Those simple truths, he believes, capture the heart of Quincy, Illinois.

Now, with a legacy built through movement, mentorship, family, and film, Dan Isaacson’s story isn’t just about where he went—it’s about how far Quincyness can take you.
