VO2 max might be one of the most underrated health metrics today, but the data is clear: improving it could be one of the best things you ever do for your fitness and longevity.
In a recent YouTube video, health and performance coach Adam shared how he transformed his VO2 max from average to elite—landing in the top 1% for his age.
His journey wasn’t about elite-level genetics or professional training camps—it was about smart strategy, consistency, and structure. Whether you’re a cardio newbie or a seasoned lifter avoiding the treadmill, here’s why your VO2 max matters and how to take yours to the next level.

What Is VO2 Max and Why Is It So Important?
VO2 max stands for “maximum volume of oxygen.” It measures how efficiently your body uses oxygen during intense exercise. In plain terms, it’s your cardio engine—the better it is, the harder and longer you can go before hitting your limit.
It’s also one of the strongest predictors of health span—the number of disease-free, functional years you live. While lifespan tells you how long you’re alive, health span tells you how well you live during those years. “Even if you don’t care about athletic performance, you’re still limited by your VO2 max,” Adam says in his video.
VO2 max reflects the health of your lungs, heart, blood vessels, and muscles—all vital for preventing disease and aging well. And unlike some genetic health factors, your VO2 max is highly trainable.
From Bodybuilder to Breathless: A Personal Wake-Up Call
Adam spent most of his 20s focused exclusively on bodybuilding. His only “cardio” came in the form of high-rep squats and extra walking during contest prep. Things changed dramatically in his early 30s after experiencing chest pain, high blood pressure, and a near-fainting episode in Rome. That moment—and the early loss of his father—became a turning point.
Despite being muscular and strong at 5’10” and 220 pounds, Adam realized he wasn’t healthy where it counted most. The physical scare pushed him to do his first 10K run in over 10 years, clocking in at 56 minutes—and so began the climb.
How He Transformed His VO2 Max
Adam’s starting VO2 max was 43, right around average for a 32-year-old male. Today, he’s hit 59—top 1% for his age and fitness level. While most research shows VO2 max improvements of 5–20%, he saw nearly a 40% increase. Here’s how he did it:
1. Structured Running Plan
He moved from inconsistent weekend jogs to a structured 3-4 day running schedule:
- 2 easy runs at conversational pace (40–60 minutes each)
- 1 interval or “workout” run at higher effort levels (up to an hour)
- 1 long run just above easy pace, gradually pushing distance
Easy runs kept him in Zone 2 heart rate (around 130–140 bpm), while harder runs built capacity and threshold tolerance. Initially using a chest strap HR monitor, Adam later switched to pacing tools when the monitor failed.
2. Reduced Weight Training Volume
Trying to maintain a 4-day bodybuilding split alongside high running volume quickly led to illness and overtraining. He cut back to 2–3 full-body strength sessions weekly—focusing on single-leg exercises and core stability—to support running efficiency without crushing recovery.
3. Nutrition and Supplementation
As a performance nutritionist, fueling became a major priority. Adam dialed in his pre-, during-, and post-run nutrition:
- Pre-run carbs for energy (e.g., carb powders)
- On-the-go fueling: one gel every 30 minutes on longer runs
- Post-run refueling to support recovery
He also supplemented with evidence-based endurance aids like:
- Beta-alanine – buffers lactic acid
- Citrulline malate – improves blood flow and recovery
- Nitrates (beetroot juice) – boosts endurance
4. Increased Training Volume Over Time
Once progress plateaued, Adam increased his running mileage to improve adaptation. From 20K per week, he gradually moved toward 30–40K. This included a fourth running session and longer long runs. Key takeaway: your VO2 max won’t keep climbing unless your inputs (i.e., total training load) grow.
5. Progressive Overload and Testing
Just like lifting, VO2 max improves with progressive overload. Adam didn’t just run randomly—he tested regularly, tracked improvements, and adjusted based on performance. A Garmin watch offered useful estimates, while a lab test provided more clarity at key checkpoints (e.g., lab-tested VO2 max score of 51 vs. 43 at start).
The Three Biggest Takeaways
1. Treat Cardio Like Strength Training
To reach the highest levels of cardiovascular fitness, intensity and structure matter. “Some of the runs were harder than any weightlifting session I’ve done,” Adam says. Simply walking or half-hearted jogging won’t trigger the gains you’re after.
2. Fuel Properly to Perform Optimally
If you treat cardio like a real workout, it deserves the same nutritional support. Most people underperform during cardio because they’re under-fueled. Once Adam added gels and pre-run carbs, his endurance skyrocketed.
3. Consistency and Enjoyment Are Key
All this wouldn’t have worked if Adam hated it. He chose running over rowing or swimming because he could stick to it. Progressing at something he enjoyed made it sustainable—and even fun. If the mode of cardio doesn’t excite you, the results won’t stick.
But What About Training Zones?
You may expect a deep dive into “Zone 2 vs. Zone 5,” but Adam downplays the obsession with heart rate zones. Instead, he emphasizes overall volume, consistency, and progression—three timeless principles regardless of the training modality.
“Elite skiers, rowers, and swimmers all have elite VO2 max scores, but they train in different ways,” he explains. There’s no one-size-fits-all. The most important thing is that you’re consistent, progressing, and pushing enough to stimulate adaptation.
The Bottom Line
Improving your VO2 max isn’t a mystery. It requires intentional expansion of your cardio engine through structured training, smart fueling, and progress-focused planning. Adam’s 6-month journey to the top 1% wasn’t magic—it was methodical.
If you’ve ignored cardio or treated it purely as a fat-loss tool, it’s time to reframe your thinking. Cardio training, when done properly, can extend your health span and physical capacity far beyond the gym.
Ready to start your own transformation? Adam has created a free VO2 max mini-course available through the link in his video description to help guide you from your current level to elite capacity—regardless of where you begin.
As he puts it, “You can have anything you want. But you can’t have everything you want.” For now, make elite health your priority. Your future self will thank you.
