Enhance your fitness and performance with the Aerobic Capacity & Heart Rate Calculator, an easy-to-use tool designed to help you estimate your VO₂ Max, Maximum Heart Rate (MHR), and Target Heart Rate (THR) zones — key indicators of cardiovascular fitness and endurance.

Whether you are an athlete, trainer, or someone focused on improving overall health, this app provides accurate fitness-based calculations grounded in established exercise science formulas.

Key Features

Aerobic Capacity (VO₂ Max) Calculator – Estimate your aerobic fitness level based on heart rate data using trusted ACSM standards.

Heart Rate Calculator – Find your Maximum and Target Heart Rate zones (50–85% of MHR) for optimal workouts.

Personalized Results – Input your resting and active heart rate or age to get tailored outcomes.

Educational References – Includes reliable medical and fitness citations for transparency.

Built-in Disclaimer – For informational and educational use only; not a medical diagnostic tool.

Formulas Used

Aerobic Capacity (VO₂ Max): VO₂ Max = 15.3 × (Maximum Heart Rate / Resting Heart Rate)

Maximum Heart Rate (MHR):

MHR = 220 − Age

Target Heart Rate (THR):

50–85% of MHR (Moderate to Vigorous Exercise Zone)
