Robert Herjavec Says His Biological Age Dropped: What Lifters Should Actually Learn
UPLIFT IRON CLUBRobert Herjavec has spent years talking publicly about fitness, but a new headline puts a very modern number on the story: the Shark Tank investor says he has cut more than a decade from both his biological-age and fitness-age scores in under a year. That sounds dramatic. It is also exactly the kind of claim that deserves a little context before anyone turns it into an anti-aging blueprint.
The useful part of Herjavec’s story is not the promise that a test can prove someone has literally become younger. It is the pattern behind the result: consistent resistance training, regular cardio, attention to body composition, recovery and a willingness to keep training while getting older. Those are practical habits. The age score is better treated as feedback than as a magic verdict.
What changed in Robert Herjavec’s fitness story
Herjavec has not suddenly discovered exercise. He has a long public history of running, cycling, lifting and bodyweight training. Years ago he described using pull-ups, squats, push-ups and deadlifts alongside cardio, and he has continued to post training clips well into his sixties. His own site now describes a routine built around cardio, strength work, intermittent fasting and recovery, with body fat around 13 percent.
The newer story is that testing reportedly showed a large improvement in biological-age and fitness-age scores over roughly 12 months. That can be motivating, especially for people who assume their physical ceiling must drop sharply after 50 or 60. But the most important observation is simpler: measurable fitness can improve at an age when many people expect only decline.
Herjavec’s routine also reflects something lifters often miss when they become obsessed with one metric. He does not train only for a bigger bench press or only for a faster run. Strength, aerobic work, body composition and daily consistency all contribute to how capable a person feels. A healthy-aging plan should look similarly broad.
Biological age is a score, not a new birth certificate
“Biological age” can refer to several different models. Some use blood markers, some use DNA methylation patterns, and others combine body composition, cardiovascular data and performance measures. A fitness-age score may lean more heavily on things such as aerobic capacity, resting heart rate or strength. Two systems can therefore give the same person different ages.
That does not make the measurements useless. Repeating the same validated assessment under similar conditions can show whether important markers are moving in a better direction. The mistake is treating a single age number as if it proves how long someone will live or how quickly every tissue in the body is aging.
For lifters, ordinary performance markers are often more actionable anyway. Can you maintain or gain muscle? Is your waist measurement moving in the right direction? Can you walk briskly without getting winded? Are your resting heart rate, blood pressure and basic health markers improving? Can you get off the floor, carry groceries and train without constantly aggravating joints? Those outcomes matter even if an app never tells you that you are “12 years younger.”
Strength training becomes more valuable with age
One of the best parts of Herjavec’s approach is that he did not stay trapped in the idea that cardio is the only route to being lean and fit. Resistance training matters because aging is not just a cardiovascular problem. Preserving muscle, strength and the ability to produce force supports independence, balance and the capacity to handle normal physical tasks.
The program does not need to become complicated. A squat or leg-press pattern, a hinge, a press, a row or pull-up variation and a few smaller movements can cover most of the body. Machines are perfectly legitimate if they make training more comfortable or stable. Bodyweight work is useful when travel makes equipment unreliable. The best exercise is the one that can be loaded progressively without repeatedly beating up the same joints.
Progress also changes meaning with training age. A younger beginner might add weight almost every session. An experienced lifter in their sixties may be winning by keeping the same muscle and strength while moving well and staying pain-free. That is not “maintenance” in the dismissive sense. Preserving high physical capacity while chronological age rises is itself a form of progress.
Aerobic fitness deserves a place beside the weights
Herjavec’s long history of running and cycling is another reason his story should not be reduced to “lift weights to stay young.” Aerobic capacity is a different quality from muscular strength. You can be strong and still get exhausted climbing several flights of stairs; you can also have good endurance while lacking enough muscle to protect strength and function.
For most lifters, the answer is not marathon mileage. Two or three purposeful cardio sessions each week plus regular walking can coexist with strength training. Easy cycling, incline treadmill work, brisk walking or rowing can build an aerobic base with relatively little muscle damage. Harder intervals can be added in smaller doses if joints and recovery tolerate them.
The interference problem is often exaggerated. Cardio becomes a lifting problem when the volume or intensity is high enough to compromise recovery. A sensible amount can improve work capacity, help someone recover between sets and make daily life easier. The goal is to be difficult to tire without making every session a conditioning test.
The practical anti-aging plan is less glamorous than the headline
If you strip away the testing language, Herjavec’s example points toward a very ordinary formula: keep muscle, keep your heart and lungs trained, manage body composition, recover well and make the routine resilient enough to survive travel and busy weeks. None of that requires an expensive longevity clinic.
A practical week could include three full-body strength sessions, two moderate cardio sessions and walking on most days. The lifting sessions might use five or six movements for two to four working sets each. The cardio sessions could last 20 to 40 minutes at a pace that is challenging but sustainable. Someone starting from a lower baseline can do less and build gradually.
Recovery is part of the plan, not an optional luxury. Sleep, adequate protein, enough total calories to support training and sensible management of aches matter more than chasing exotic recovery tools. Herjavec has spoken about using technologies such as red-light therapy and hyperbaric chambers, but those should not distract from the fundamentals that do most of the work.
Body composition matters too, but aggressive dieting can work against the goal if it strips away muscle or makes training collapse. A slower approach that preserves performance is usually more compatible with healthy aging. Waist circumference, strength trends and energy levels can be more useful day-to-day feedback than obsessing over the lightest possible scale weight.
The final lesson is psychological. Herjavec has repeatedly emphasized consistency and adapting when travel makes a perfect gym impossible. That is probably more valuable than any single exercise in his routine. A program that only works under ideal conditions is fragile. A plan with substitutions, shorter fallback sessions and a minimum weekly target can keep moving when life gets messy.
That also means choosing tests carefully. If a biological-age dashboard motivates you to improve habits, it can be useful. But do not let a proprietary score outrank obvious reality. If the number improves while strength, sleep, blood pressure or exercise tolerance gets worse, the score should not win the argument. The best measurement system is one that helps you make better decisions and can be repeated consistently.
For older lifters, the strongest target is capability. You want enough leg strength to climb stairs easily, enough upper-body strength to move and carry things, enough aerobic fitness to stay active for hours, and enough mobility to use that strength through useful ranges. Those goals are not as flashy as reversing a biological clock, but they are concrete, trainable and visible in everyday life.
The exciting interpretation is that Robert Herjavec became more than a decade younger. The more defensible interpretation is that a man in his sixties improved a set of health and fitness markers enough for age-based scoring systems to rate him substantially better. That is still a strong result.
You do not need the same score to benefit from the same direction of travel. Build or preserve strength. Train your aerobic system. Stay active outside formal workouts. Keep body fat in a healthy range without sacrificing muscle. Recover well enough to repeat the work. Measure progress with markers you can actually act on.
Chronological age only moves one way. Physical capacity is more negotiable. That is the part of the story worth chasing.
