VO2 Max Estimator
Estimate your cardiovascular fitness without a test using age, weight, and heart rate
About VO2 Max
VO2 max represents the maximum amount of oxygen your body can utilize during intense exercise. It’s a key indicator of cardiovascular fitness and aerobic endurance.
How This Estimator Works
This calculator uses the Uth-Sørensen-Overgaard-Pedersen estimation formula which correlates resting heart rate, age, and other factors with VO2 max. While not as accurate as laboratory testing, it provides a reasonable estimate for most adults.
Interpreting Your Results
VO2 max values vary by age and gender. Generally, higher values indicate better cardiovascular fitness. Elite endurance athletes often have VO2 max values above 60 ml/kg/min.

Here’s the Truth About Your Fitness Level
I used to think VO2 max was something only Olympic athletes worried about. Then my doctor mentioned mine during a routine checkup—turns out, it’s like a credit score for your heart and lungs. The good news? You don’t need expensive tests to ballpark yours.
This calculator gives you a real-world estimate using three things you already know:
How many candles were on your last birthday cake
What you see when you step on the scale
Your resting pulse (check it right now—I’ll wait)
Why This Matters More Than You Think
✔ Health Snapshot: Low VO2 max? Higher risk for heart issues
✔ Fitness Tracker: See if your workouts are actually working
✔ Motivation Boost: Nothing like cold, hard numbers to get you moving

How We Estimate Your Fitness (Without the Lab Goggles)
We use the same math personal trainers rely on when they can’t hook you up to machines. Your results factor in:
🔹 Age: Sorry millennials, fitness does decline after 30
🔹 Weight: More body = more oxygen needed
🔹 Resting Heart Rate: Lower is usually better (mine’s 58—thanks, coffee)
🔹 Activity Level: Be honest—Netflix marathons don’t count
Pro Tip: Take your pulse first thing in the morning for the most accurate number.
What Your Number Really Means
| Fitness Level | Men (ml/kg/min) | Women (ml/kg/min) | What It Feels Like |
|---|---|---|---|
| Elite | 60+ | 50+ | “I run for fun” types |
| Great | 52-60 | 45-50 | Regular gym-goers |
| Good | 43-51 | 38-44 | Can hike without dying |
| Meh | 35-42 | 30-37 | Gets winded climbing stairs |
| Time to Move | Below 35 | Below 30 | “Elevator broken? I’ll wait” |
My first score? 41. After 3 months of lunchtime walks? 46. Small wins.
5 Ways to Boost Your Score (That Don’t Suck)
1. The Coffee Walk
Do your morning caffeine stroll briskly
20 minutes, 4x/week = noticeable difference
2. Commercial Break Workouts
Do bodyweight squats during ads
3 episodes = accidental cardio
3. Park Farther Away
Adds 500+ extra steps daily
Pro move: Make it a game (“Beat yesterday’s time”)
4. Dance Like Nobody’s Watching
15 minutes to upbeat music = best stealth cardio
Bonus: Great for your mental health
5. Take the Stairs (Sometimes)
Start with just 1 flight daily
Works better than resolutions you’ll forget by February
Questions Real People Actually Ask
“My score’s terrible—am I doomed?”
Nope. My friend went from 32 to 44 in 6 months just by walking his dog faster. Start small.
“Does being sore affect the results?”
Only if you take your pulse while cursing leg day. Wait until normal soreness fades.
“Why does my Apple Watch show something different?”
Wearables guess based on heart rate during activity. Ours uses resting rate for a baseline.
