Life Fitness developed this rating scale based on VO2 max percentile distributions referenced in American College of
Sports Medicine’s Guidelines for Exercise Testing and Prescription (8th E. 2010). It is designed to provide a qualitative
description of a user’s VO2 max estimation, and a means of assessing initial fitness level and tracking improvement.
