Fitness Index

Your Smart Trainer / Trainer Pro will generate a fitness index based on your aerobic fitness, or your capacity to engage any forms of aerobic exercise, dependent and limited by the body’s ability to deliver oxygen to the working muscles in training. It is often measured by maximum oxygen uptake (VO2 Max), which is defined as the highest amount of oxygen that can be utilized when exercising at an increasingly demanding level. The lungs, heart, blood, circulatory system, and working muscles are all factors in determined VO2 Max. The unit of VO2 Max is ml/kg.min.

Generally, the fitness range lies between 13 to 53 depend on ages. The higher the index, the fitter you are. (Refer to the following diagram for reference.)
