A fitness coach who’s helped multiple clients boost their VO2 Max by 10 to 20 points in just three months is breaking down exactly how anyone can improve this critical health marker.
VO2 Max isn’t just another fitness metric to track on your smartwatch.
Research shows it’s the single best predictor of longevity, and improving it means pushing harder before fatigue sets in while recovering faster between sessions.
In a recent video, the coach teamed up with Vinton, an athlete who’s maxed out Whoop’s VO2 Max readings for an entire year, recorded an 84 VO2 Max in lab testing, runs marathons in 2 hours 25 minutes, and clocks mile times at 4 minutes 40 seconds.

Level One: Foundation Nutrition and Recovery
Before diving into complex training protocols, three fundamental factors need attention. Miss these basics, and even perfect programming won’t move your numbers.
Iron, B12, and B9: Your Red Blood Cell Trinity
High-volume cardio literally destroys red blood cells through repeated impact. Sweat compounds this problem by leaching iron, yet most endurance athletes remain chronically deficient without realizing it.
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
When the coach first tested his blood two years ago, hemoglobin levels came back alarmingly low. Iron alone won’t fix this issue—vitamins B12 and B9 are essential for building new red blood cells.
Optimize your diet with these specific foods:
- Iron: Red meat and spinach
- Vitamin B12: Eggs and salmon
- Vitamin B9: Lentils and asparagus
Supplementation should only fill gaps revealed by blood work. Iron supplements carry real risks, including oxidative stress and liver damage. If supplementing iron becomes necessary, heme iron is the superior choice.
B12 and B9 supplements present no harm, but quality matters tremendously. Most supplements use folic acid—a cheaper form of B9 that’s difficult for bodies to absorb. Methylfolate is the active form cells can actually utilize.
Methylfolate supplementation was a small thing that I did that had crazy changes in how I felt.
Active Recovery: Movement Beyond Training
Vinton’s non-negotiable habit? A 10-minute walk after every meal. He averages 20,000 steps daily, walking roughly five minutes every hour.
This isn’t about hitting arbitrary step counts. Circulation increases two to three times during active movement compared to sitting. Walking, light biking, or any easy-effort activity keeps blood flowing without creating training stress.

Strategic Nutrition Timing
Most athletes either overeat before training and feel sluggish or eat nothing and crash mid-session. Nutrition needs vary dramatically based on intensity.
Easy and medium effort days: Stored glycogen handles low-intensity work without additional fuel. Training fasted is completely fine. Add electrolytes—primarily sodium—on medium days to regulate fluid balance and prevent cramping.
Hard training days: This is where intervals, threshold runs, and long efforts live. At high intensity, bodies run almost exclusively on carbohydrates. Fat can’t deliver energy fast enough at maximum output.
Pre-workout, you want something light like a banana or a bagel that digests extremely fast and gives you a lot of quick energy.
Before hard sessions, consume 30 to 60 grams of fast-digesting carbs. During workouts lasting over an hour, take in roughly 30 grams of carbs hourly. This replaces glucose burning through muscles and maintains energy output.
Avoid fiber and fat before intense training. Both slow digestion dramatically and can cause mid-workout cramping. Save fiber-rich and fat-heavy meals for post-workout or easy days.
Level Two: Choosing Your Training Vehicle
Should you run, bike, swim, row, or mix them all? Each option presents real trade-offs depending on session type.
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.

Sports producing the highest VO2 Max numbers share one characteristic: they demand simultaneous work from maximum muscle mass. More muscle firing means hearts must work harder supplying them.
Cross-country skier Bjørn Dæhlie holds the highest recorded VO2 Max ever at 96, proving this principle. Skiing requires full-body demand sustained over long duration.
Running: Convenience Meets High Stimulus
Running delivers the highest cardiovascular stimulus with zero setup required. You can train literally anywhere, which drives consistency.
However, running carries the biggest injury risk. High volume wears down knees, joints, and Achilles tendons. Proper shoe fitting isn’t optional—it’s injury prevention.
Cycling: Joint-Friendly Volume Builder
Cycling presents minimal injury risk and goes easy on joints. Perfect for zone two days and building aerobic base.
The limitation? On hard days, legs fatigue before hearts reach their ceiling. Quads give out before cardiovascular capacity, which is exactly opposite what’s needed for pushing VO2 Max.

Rowing: The Underrated Powerhouse
Rowing engages approximately 86% of muscles simultaneously—upper body, lower body, and core all firing together. Hearts must work harder than almost any other activity.
Injury risk sits close to zero, and elite rowers consistently test among the highest VO2 Max numbers ever recorded. If access to rowing machines exists, this option deserves serious consideration.
Swimming: Technical Limitations Apply
Swimming offers ultra-low impact with zero injury risk. However, chlorine exposure affects airways over time, and poor technique means burning energy staying afloat rather than building cardiovascular output.
The best vehicle is the one you’ll show up for consistently without dreading workouts. Picking activities you genuinely enjoy trumps theoretical optimization.
Level Three: Programming Your Training
Every VO2 Max workout falls into specific session types. Understanding each one unlocks intelligent programming.
Essential Session Types
Easy runs: Conversational pace that feels almost too easy. This becomes the majority of weekly volume—classic zone two cardio.
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
Strides: Twenty-second bursts at fast effort tacked onto easy runs. These remind legs what speed feels like. Athletes doing only easy running gradually lose fast-twitch muscle fibers, which only develop through regular fast stimulus.
Intervals: Short, hard, repeated efforts with full recovery between sets. Formats worth rotating include:
- Five sets of 400 meters
- Four sets of 800 meters
- Three sets of 1 mile
- Two sets of 2 miles
- Norwegian 4×4 protocol
Each format hits cardiovascular systems at slightly different intensities. Mixing these across weeks prevents adaptation to identical stimulus.
Tempo and threshold runs: Tempo runs sustain hard effort at goal marathon pace for 20 to 40 minutes. Threshold runs push slightly harder—the fastest pace sustainable for roughly one hour.
Threshold training specifically targets lactic threshold. When running hard, muscles produce lactate as byproduct. At easy efforts, bodies clear it as fast as production occurs. Push too hard and lactate builds faster than clearance, causing burning legs and forced slowdowns.
Training at threshold consistently pushes that breaking point higher, enabling faster sustained speeds and raising VO2 Max ceiling.

- 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
Sprints: Full 100% effort at maximum speed for 20 to 30 seconds. Unlike intervals, there’s no target pace—just absolute top-end speed training neuromuscular power.
Long runs: Extended zone two training or extended hard effort depending on the week. This builds aerobic base and mitochondrial capacity.
Beginner Protocol: Three Days Weekly
For beginners or maintenance, three weekly sessions will improve VO2 Max. Focus entirely on building aerobic base.
- Day 1 and 3: 30 to 40-minute easy zone two run
- Day 6: 45 to 60-minute long run
Alternate long run intensity every two weeks—zone two one week, uncomfortable zone three the next. Bodies should never fully adapt to workouts.
Intermediate Protocol: Four to Five Days Weekly
This level follows the 80% easy, 20% hard principle with four to five cardio sessions weekly.
Day 1: Easy zone two run for 40 to 50 minutes, finishing with six to eight strides (20-second run with 30-second walk). Skip strides if feeling sore or unwell, but complete the zone two work.

- Solid cast iron build that feels stable and lasts for years
- Comfortable grip that makes high-rep workouts easier to handle
Day 3: Alternate between interval training and 20 to 30-minute tempo runs at sustainable hard pace.
Day 5: Short intervals with rotating formats—five sets of 400 meters in week one, three sets of 800 meters in week two, two sets of 1 mile in week three, then cycle back.
Day 6: Long run alternating between easy and hard efforts, lasting 60 to 90 minutes.
Day 7: Complete rest.
Advanced: Get Tested and Personalized
Maximizing VO2 Max at advanced levels requires laboratory testing breaking fitness into three components:
Aerobic power: Heart’s engine size determining training capacity. Train with easy runs, long runs, tempo runs, threshold runs, and Norwegian 4×4 protocols.

- Comfortable grip that makes high-rep workouts easier to handle
Anaerobic battery: Like a phone battery draining when running faster than aerobic systems can handle. Develop with 400-meter and 800-meter intervals.
Processing power: Think iPhone 16 versus iPhone 3—faster top-end speed creates more headroom at every pace below it. Train with pure sprints and strides.
Testing reveals exact paces for every run type based on oxygen consumption and carbon dioxide exhalation at each pace. This data identifies specific limiters.
For me, when trying to increase VO2 Max, doing active recovery is super important. Personally what I do is I walk literally a lot. I walk like 5 minutes every hour. I average 20,000 steps a day.
Vinton’s testing showed elite aerobic power—4-minute 48-second VO2 Max pace and 5-minute 20-second threshold pace. His limiter? Anaerobic battery.
For athletes limited by anaerobic capacity, following standard 80/20 protocols does nothing. Vinton shifted to 60% easy running, 30% anaerobic work, and 10% aerobic power for breakthrough results.
If aerobic power limits you (most beginners and intermediates), stick closer to 80% easy zone two and 20% hard aerobic intervals like Norwegian 4×4, mile repeats, and threshold runs.

If processing power limits you, program 75% aerobic power work, 15% anaerobic battery work, and 10% pure sprints. Sprint work becomes non-negotiable—most endurance athletes never touch this zone, which is why their speed plateaus completely.
Level Four: Injury Prevention Fundamentals
One bad injury can erase six weeks of hard work. Training only works when staying healthy enough to maintain consistency.
Keep Easy Days Actually Easy
Zone two days must remain genuinely easy. This recovery forms the backbone enabling hard efforts. Without proper recovery, hard training becomes impossible.
Walking breaks during easy runs carry zero shame. Sometimes alternating two-minute running with one-minute walking keeps intensity appropriate.
Fix Your Cadence
Most runners overstride, landing feet too far forward with each step. Every overstride strains Achilles tendons.
Studies show overstriding increases impact force up to 30% compared to shorter strides landing underneath bodies. That extra force becomes shin splints, stress fractures, and knee pain.

Higher cadence means more frequent, shorter steps with feet nearly always touching ground. This dramatically reduces joint impact while improving running economy.
It’s important you don’t run on concrete and you run on grass. There’s literally so much more absorption in the grass versus the concrete, which absorbs 0%. It’s like actually 30% lower risk of injury.
Master Warm-Up and Stretching Timing
Before runs—dynamic warm-ups only:
- Five minutes easy walking
- Leg swings (front to back, side to side)
- Hip circles
- Walking lunges
- A-skips
- Four to six short strides
Keep warm-ups under 10 minutes total.
After runs—static stretching time: Hold each stretch 30 to 60 seconds, focusing on hip flexors, hamstrings, calves, and glutes. These four areas absorb the most load during running.
Post-run stretching improves long-term flexibility and reduces next-day tightness.
Replace Shoes Every 300 to 500 Miles
Midsole foam absorbing impact loses roughly 40% of shock absorption by 300 to 500 miles. Track mileage per shoe and replace on schedule.

Having two pairs of identical running shoes for rotation extends lifespan and allows proper drying between sessions. Consider adding lighter shoes with carbon plates for tempo work once speed exceeds 8-minute miles.
Prioritize Sleep Above Everything
Tendons, muscles, and connective tissues repair during sleep, not during cardio sessions. Research shows athletes sleeping less than seven hours nightly are 1.7 times more likely suffering injuries than those getting eight-plus hours.
Minimum sleep targets:
- Long run days: 8 hours
- Training days: 7.5 hours
- Regular days: 7 hours
Sleep consistency matters tremendously. Going to bed at identical times nightly affects recovery as significantly as total duration.
Level Five: Understanding Volume Reality
Athletes with VO2 Max scores in the 80s to 90s—world-class cross-country skiers—average 20 hours weekly training. Vinton has maintained 20 to 25 hours weekly for three straight years.
But 99.9% of people watching won’t approach that volume. Life exists, work exists, other training goals exist.

If health is the goal, VO2 Max shouldn’t be optimized in isolation. Health is a multivariate problem—optimizing one metric without considering others creates imbalances.
Unless you’re a professional athlete, 25-hour running weeks will tank muscle mass, wreck recovery, disrupt hormone levels, and squeeze out everything else contributing to health.
The coach works in 90-day cycles: winter builds muscle mass, spring boosts VO2 Max, summer develops strength, fall increases HRV and stress resilience.
Even during focused VO2 Max seasons, he caps cardio at seven hours weekly maximum. This volume delivers 90% of benefits without overstraining.
My goal is not to be a professional athlete. I’m trying to be healthy as possible across every dimension.
Set ceilings based on your life and current season. Follow the 5% progression rule relative to your personal ceiling. For pure VO2 Max improvement among those tested, 800-meter training produces the most effective distance stimulus.
Sustainable improvement beats unsustainable perfection. Choose training volume you can maintain consistently while preserving other health dimensions, and your VO2 Max will climb steadily over time.
