Aerobic Capacity Calculator
The Aerobic Capacity Calculator estimates your VO2 Max based on your age, gender, resting heart rate, and activity level. This tool helps fitness enthusiasts and athletes accurately assess their cardiovascular fitness and training needs. Whether you want to track progress, determine your fitness category, or find your ideal heart rate training zones, this calculator provides clear, actionable insights.
How VO2 Max Is Calculated
VO2 Max measures the maximum amount of oxygen your body can utilize during intense exercise. This metric is crucial because it indicates your cardiovascular endurance and overall aerobic power.
The calculator estimates this value by first determining your Maximum Heart Rate (220 minus your age) and then analyzing your resting heart rate against your self-reported activity level. By comparing your heart rate data to your demographic details, the tool generates a reliable estimate of your fitness capacity without requiring a physical exertion test. This method offers a convenient baseline for tracking your health improvements over time.
What Your VO2 Max Means
Your VO2 Max score tells you how efficiently your body uses oxygen during exercise. This number helps you understand if your current routine is improving your heart health or if you need to push harder.
Assess Fitness Level
For men under 30, a score below 35 is considered "Poor," while over 55 is "Superior." For women under 30, the range shifts to below 28 for "Poor" and above 48 for "Superior." Use these benchmarks to see where you stand.
Plan Training Zones
Use your specific score to set heart rate limits for your workouts. Staying in the correct zone ensures you are burning fat or building endurance as intended rather than overtraining.
Track Progress
If your score improves by just 3-5 mL/kg/min over a few months, your cardiovascular health is significantly better. Aim for small, consistent increases rather than massive jumps.
Important: Fitness categories vary significantly by age, so ensure you compare your result against the correct age bracket.

Track your resting heart rate monthly; as it drops, your VO2 Max should naturally rise, signaling better fitness.
