At 64, most people are thinking about slowing down.
Robert Herjavec decided to turn back the clock instead.
The longtime Shark Tank investor and cybersecurity mogul just reversed his biological age and fitness age by more than a decade—in less than 12 months.
And he did it by doing something most high-achievers refuse to do: admit he didn’t know everything and hire help.

The Transformation That Defied Age
Clinical testing conducted throughout Herjavec’s transformation program showed both his biological age and fitness age dropped by more than ten years in under 12 months, according to a detailed profile published by Men’s Health Australia.
This wasn’t a typical weight-loss story. Herjavec was already fit—lean enough to maintain 13% body fat at age 62, as Muscle & Fitness reported in 2025.
If you want something simple that actually works, this is one of the most effective tools I’ve used to build strength, conditioning, and endurance without needing a full gym setup.
- Full-body training with one weight using swings, squats, and presses
- Solid cast iron build that feels stable and lasts for years
- Comfortable grip that makes high-rep workouts easier to handle
But being fit and getting younger are two different things entirely.
To achieve this dramatic reversal, Herjavec partnered with Australian coaches Chief Brabon and Emilie Brabon-Hames of TransformationCoach.com. Together, they designed a structured protocol targeting not just body composition, but measurable markers of aging itself.
From Dancing With the Stars to Shark Tank’s Fittest Investor
Herjavec’s fitness journey didn’t start overnight.
Back in 2015, he appeared on Dancing With the Stars, where he met his now-wife, professional dancer Kym Johnson. During just the first month of rehearsals, he dropped 10 pounds while learning complex choreography.
By 2018, Men’s Health US profiled him as arguably the fittest investor on Shark Tank. His commitment to training had become part of his identity—right alongside his reputation as a shrewd businessman who founded BRAK Systems (sold to AT&T Canada) and later The Herjavec Group, a major cybersecurity firm.
But even with decades of consistent training, Herjavec had hit what he thought was his ceiling.

I used to tell myself I was as fit as my body would allow.
That mindset changed when he decided to work with elite coaches who could push him beyond self-imposed limits.
Why Biological Age Matters More Than Chronological Age
Biological age refers to how old your body actually is based on cellular health, metabolic function, cardiovascular capacity, and other physiological markers.
It’s different from chronological age—the number on your birth certificate.
Scientists measure biological age using tools like:
- VO2 max testing (cardiovascular fitness and oxygen utilization)
- Epigenetic clocks (DNA methylation patterns that predict aging)
- Telomere length (protective caps on chromosomes that shorten with age)
- Functional fitness benchmarks (strength, mobility, and endurance metrics)
Herjavec’s reported 10-year reduction suggests dramatic improvements across multiple systems—not just muscle or fat loss, but fundamental changes in how his body functions at a cellular level.
While the specific testing methodology used by his coaches hasn’t been independently verified, the results align with emerging longevity research showing lifestyle interventions can meaningfully reverse biological aging markers.

The Fitness Protocol That Changed Everything
What exactly did Herjavec do differently?
While complete program details remain proprietary to TransformationCoach.com, the framework likely included:
- Progressive resistance training tailored to optimize strength without overtraining
- Strategic cardiovascular work designed to improve VO2 max and metabolic efficiency
- Periodized programming that cycles intensity to prevent adaptation plateaus
- Optimized nutrition timing to support recovery and body recomposition
- Advanced recovery protocols including techniques Herjavec had already been exploring
Recovery was particularly crucial. In his 2025 Muscle & Fitness interview, Herjavec identified recovery as his “biggest challenge.”
He’d already experimented with cutting-edge modalities including red light therapy, hyperbaric oxygen chambers, and PEMF (pulsed electromagnetic field therapy). Under structured coaching, these tools were likely integrated more systematically.
The Mindset Shift That Made It Possible
Perhaps the most remarkable aspect of Herjavec’s transformation wasn’t physical at all.
It was psychological.

- Full-body training with one weight using swings, squats, and presses
- Solid cast iron build that feels stable and lasts for years
- Comfortable grip that makes high-rep workouts easier to handle
Here’s someone who had built multiple successful companies, appeared on national television for two decades, and maintained impressive fitness for years. Yet he recognized he needed expert guidance to break through to another level.
That willingness to be coached—to unlearn limiting beliefs about what his body could achieve—separated this transformation from previous plateaus.
Men’s Health Australia emphasized this wasn’t just about physical results. It was about challenging the narrative that decline after 60 is inevitable.
The Father of Young Children Who Refuses to Get Old
Herjavec’s motivation runs deeper than vanity or competitive drive.
He has five children, including 7-year-old twins with wife Kym Johnson, whom he married in 2016 after meeting during Dancing With the Stars.
Fatherhood at this stage of life created unique motivation.

I’m not afraid of getting older. I’m afraid of becoming old in their eyes.
That distinction matters. Getting older is chronological and unavoidable. Becoming old—losing vitality, energy, physical capability—is optional.
Herjavec wants to run, play, and keep up with his young children for decades to come. That requires maintaining—and even improving—functional fitness as he ages.
Part of a Larger Longevity Movement
Herjavec’s transformation places him alongside other wealthy executives investing heavily in longevity optimization.
Tech entrepreneur Bryan Johnson famously spends millions annually attempting to reverse aging through extreme protocols. Physician Peter Attia has popularized “Medicine 3.0″—a preventive approach focused on extending healthspan, not just lifespan.
What makes Herjavec’s approach noteworthy is its apparent balance. He didn’t retreat from business or family life to pursue fitness obsessively. Instead, elite coaching helped him optimize results within realistic time constraints.
That makes his transformation more relatable—and potentially more replicable—for busy professionals who can’t dedicate every waking hour to biohacking.

What This Means for Men Over 40
Herjavec’s results offer powerful evidence that significant biological improvements remain possible well into your 60s.
But several key lessons emerge:
- Expert coaching matters — even for already-fit individuals, structured programming produces results DIY approaches can’t match
- Recovery is non-negotiable — training intensity must be balanced with strategic rest and recovery protocols
- Mindset precedes results — believing improvement is possible creates space for actual change
- Consistency beats intensity — sustainable 12-month protocols outperform unsustainable 12-week crash programs
- Testing provides accountability — objective biological markers create clear targets and motivation
The science behind biological age reversal continues evolving rapidly. While some researchers remain skeptical about dramatic claims, mounting evidence suggests comprehensive lifestyle interventions can produce measurable improvements in aging biomarkers.
The Takeaway
Robert Herjavec’s transformation proves age doesn’t have to mean decline.
At 64, after two decades on television and a lifetime of entrepreneurship, he chose to invest in himself with the same seriousness he invests in businesses on Shark Tank.
The result? Biological markers suggesting his body is functioning more than a decade younger than his birth certificate indicates.

- Full-body training with one weight using swings, squats, and presses
- Solid cast iron build that feels stable and lasts for years

Whether motivated by young children, competitive drive, or simple refusal to accept conventional aging trajectories, Herjavec demonstrates what becomes possible when ego steps aside and expert guidance steps in.
His message is clear: Your best years don’t have to be behind you—even if you’re already past 60.
