Quick Answer
A good VO2 max for men ranges from 30–40 ml/kg/min for average fitness, 40–50 ml/kg/min for good fitness, and 50–60+ ml/kg/min for highly trained athletes. VO2 max declines roughly 5–10% per decade after age 25, but regular training can significantly slow this decline. Use the chart below to see where you sit for your age group.

| 40–49 | <30.2 | 30.2–33.5 | 33.6–38.9 | 39.0–43.7 | 43.8–48.0 | ≥48.1 |
| 50–59 | <26.1 | 26.1–30.9 | 31.0–35.7 | 35.8–40.9 | 41.0–45.3 | ≥45.4 |
| 60+ | <20.5 | 20.5–26.0 | 26.1–32.2 | 32.3–36.4 | 36.5–44.2 | ≥44.3 |
These categories are for the general population, not athletes. If you train regularly for running, cycling, or triathlon, you should be aiming for the “good” to “excellent” range at minimum. Your personal improvement over time matters more than which category you start in.
What These Numbers Actually Mean
A VO2 max in the mid-30s means you can jog, cycle, or play casual sport without excessive breathlessness. The mid-40s puts you in solid recreational fitness territory — you could comfortably complete a half marathon or century ride with training. Above 50, you’re in competitive endurance athlete range. Elite male endurance athletes (Tour de France cyclists, Olympic marathon runners) typically score 70–85+.

| VO2 Max Range (ml/kg/min) | What It Feels Like | Typical Profile |
|---|---|---|
| <30 | Breathless climbing stairs or walking uphill | Sedentary, very low fitness |
| 30–39 | Can jog short distances, moderate daily activities feel manageable | Lightly active, occasional exerciser |
| 40–49 | Comfortable running 5–10K, cycling 50–80 km, playing full team sports | Regular exerciser, recreational athlete |
| 50–59 | Can race half marathons, compete in age-group triathlon, hold strong cycling pace | Trained endurance athlete |
| 60–69 | Competitive at regional level, strong race performances | Serious competitive athlete |
| 70+ | Elite-level endurance capacity | Professional/elite endurance athlete |
How to Test Your VO2 Max
There are three main ways to measure VO2 max, ranging from highly accurate lab tests to free field tests you can do today.
👉 Swipe to view full table
| Method | Accuracy | Cost | How It Works |
|---|---|---|---|
| Lab test (gold standard) | ±1–2 ml/kg/min | $150–$300 AUD | Treadmill or bike at increasing intensity while breathing through a mask that measures oxygen and CO2 exchange |
| Smartwatch estimate (Garmin, Apple Watch, Polar) | ±3–5 ml/kg/min | Free (with device) | Estimates based on heart rate, pace, and personal data. Best for tracking trends. Learn how Garmin calculates VO2 max |
| Cooper 12-minute run test | ±5–8 ml/kg/min | Free | Run as far as possible in 12 minutes. Formula: VO2 max = (distance in metres − 504.9) ÷ 44.73 |
For most people, a smartwatch estimate is accurate enough for tracking progress. Test under similar conditions each time (rested, same course, similar weather) and look at the trend over weeks and months rather than any single reading.
Why VO2 Max Declines with Age — and How to Slow It
VO2 max peaks around age 20–25 and declines roughly 10% per decade in sedentary men. After 50, the decline can accelerate to 15% per decade. Several factors drive this: maximum heart rate drops about 1 beat per year, muscle mass decreases, and lung elasticity reduces.
The good news is that regular training cuts the decline dramatically. Active men lose as little as 5% per decade — and even men in their 60s and 70s can significantly improve their VO2 max with structured training.

| Activity Level | VO2 Max Decline Per Decade | What This Means at Age 60 |
|---|---|---|
| Sedentary | 10–15% | A man who scored 50 at age 25 may be at 25–30 by age 60 |
| Moderately active (3–4 sessions/week) | 5–8% | Same man may be at 35–40 by age 60 |
| Highly trained (structured endurance training) | 3–5% | Same man may be at 40–45 by age 60 |
The takeaway is clear: you can’t stop the decline entirely, but you can control the speed. A fit 60-year-old can easily have a higher VO2 max than a sedentary 30-year-old.
How to Improve Your VO2 Max
VO2 max responds well to training at any age. Research shows untrained men can improve by 15–30% with structured training, while already-fit athletes can gain 3–8% per focused training block.
The most effective training methods, ranked by impact:

| Method | How to Do It | Expected Improvement |
|---|---|---|
| VO2 max intervals | 3–5 × 3–5 min at 90–95% max HR, with equal recovery. 1–2 sessions per week. | Largest single driver of VO2 max gains. 5–10% improvement in 6–8 weeks. |
| Tempo / threshold work | 20–40 min at "comfortably hard" pace (85–90% max HR) | Improves the percentage of VO2 max you can sustain, boosting race performance |
| Long steady endurance | 60–120 min at easy, conversational pace (zone 2) | Builds aerobic base, mitochondrial density, and fat-burning efficiency. See our zone 2 and VO2 max guide |
| Strength training | 2 sessions per week of compound movements (squats, deadlifts, lunges) | Supports muscle mass retention, which preserves VO2 max as you age |
| Weight management | Reduce excess body fat through nutrition and training | VO2 max is expressed per kg of body weight — losing fat directly raises the number |
The best approach combines all of these: mostly easy aerobic work (80% of training time), with 1–2 hard interval sessions per week, plus strength training. This is the same 80/20 model used by elite endurance athletes worldwide. For specific interval sessions, see our guides on VO2 max workouts for runners and VO2 max exercises for cyclists.
VO2 Max vs Other Fitness Metrics
VO2 max is important, but it’s not the only number that matters. Here’s how it compares to other key metrics and when each one is most useful.
👉 Swipe to view full table
| Metric | What It Measures | Best For |
|---|---|---|
| VO2 max | Maximum oxygen uptake — your aerobic ceiling | Overall cardiovascular fitness, health screening, long-term tracking |
| Lactate threshold | The intensity where lactate accumulates faster than you can clear it | Race pacing, predicting endurance performance. Often a better race predictor than VO2 max alone |
| FTP (cycling) | Maximum sustainable power for ~1 hour | Setting cycling training zones and tracking cycling-specific fitness. See our average FTP by age chart |
| Resting heart rate | Heart rate at complete rest | Daily readiness and recovery monitoring. A rising trend may signal overtraining or illness |
| Running economy | Oxygen cost at a given pace | Efficiency gains — two runners with identical VO2 max can have very different race times based on economy |
Think of VO2 max as your engine size. Lactate threshold is how efficiently that engine runs. Running or cycling economy is the aerodynamics. You need all three for peak performance — but VO2 max is the easiest to track and the most strongly linked to overall health.
FAQ: VO2 Max for Men
What is a good VO2 max for a 40-year-old man?
For men aged 40–49, a VO2 max of 38–41 ml/kg/min is average, 42–47 is good, and 48+ is excellent. These ranges are based on Cooper Institute data for the general population. A trained runner or cyclist in their 40s will typically sit in the 45–55 range.
How does VO2 max change with age?
VO2 max peaks around age 20–25 and declines roughly 10% per decade. After 50, the decline can accelerate to around 15% per decade. However, regular endurance training can cut this rate in half — active men lose as little as 5% per decade compared to 10–15% for sedentary men.
Can I improve my VO2 max after 50?
Yes. Research shows men aged 60+ can improve VO2 max by up to 15–20% with structured endurance training over 6–9 months. High-intensity intervals (2–4 minutes at 90–95% max heart rate) are the most effective single method, combined with a base of steady aerobic work.
How accurate is my Garmin or Apple Watch VO2 max?
Garmin estimates are typically within 3.5 ml/kg/min of lab-tested values (about 95% accuracy) when used consistently during outdoor runs with accurate heart rate data. Apple Watch uses a similar approach. Both are reliable for tracking trends over time, though individual readings can vary day to day.
Is VO2 max or lactate threshold more important for racing?
For long-distance events (half marathon, marathon, Ironman), lactate threshold and running economy are usually better predictors of race performance than VO2 max alone. VO2 max sets your ceiling — it determines how high your threshold can potentially go — but threshold determines what pace you can actually hold. Both matter, and both improve with structured training.
VO2 Max and Longevity: Why This Number Matters Beyond Sport
VO2 max isn’t just a fitness metric for athletes. Research increasingly shows it’s one of the strongest predictors of how long you’ll live and how well you’ll age.
A large-scale 2018 study in JAMA Network Open found that men with elite cardiovascular fitness had the lowest risk of death from all causes — and the benefit was continuous, meaning every improvement in VO2 max reduced mortality risk further. The American Heart Association now classifies cardiorespiratory fitness (quantified as VO2 max) as a clinical vital sign, placing it alongside blood pressure and cholesterol as a core health indicator.
Higher VO2 max is associated with lower risk of heart disease, better insulin sensitivity, stronger immune function, and greater cognitive health as you age. The practical takeaway: even if you never race, improving your VO2 max from “poor” to “average” or “average” to “good” has a measurable impact on your healthspan.
You’re Not Just a Number - But It’s a Number Worth Knowing
Your VO2 max gives you a single, reliable number for where your cardiovascular fitness sits right now. Use the chart above to find your category, track your number over months (not days), and focus on steady improvement rather than hitting a specific target overnight.
The most effective path is consistent aerobic training with 1–2 hard sessions per week — the same approach that works for elite athletes works for everyone. And if your main goal is health rather than performance, the science is clear: every step up on the VO2 max chart reduces your risk of chronic disease and extends your healthspan.
Start where you are. Test, train, retest. The number will move.
Our coaching programmes combine easy aerobic work, targeted intervals, and strength training — the same approach that drives VO2 max improvements at every age. Whether you run, ride, or do both, we'll build a plan around your goals and schedule.
