VO2max Estimator
The V stands for "volume" while O2 is the chemical notation for oxygen. VO2 max, also known as "maximal oxygen uptake" can be expressed in many ways (from liters of oxygen per minute or the more normalized milliliters of oxygen per kilogram of bodyweight per minute). It is a way to not only compare the performance of endurance athletes, but is also a relative indicator of overall fitness. Oxygen consumption has a direct link to energy expenditure. Therefore, maximum oxygen uptake is a direct measurement of aerobic capacity. Use this calculator to estimate your VO2 Max.

Body Mass Index, or BMI, is a simple formula that expresses the ratio of body weight to height. Insurance companies use BMI as a risk factor for health. BMI is often used to categorize someone as underweight, normal weight, overweight, or obese. Because BMI does not take into account percentage of body fat, it is not a very accurate method (someone with lots of muscle mass may be overweight on the BMI scale yet have low body fat and be in great general health).
