What is VO2 Max on the Amazfit Cheetah 2 Pro?

VO2 Max measures the maximum volume of oxygen your body can use during intense exercise and serves as a benchmark for your aerobic fitness. The watch calculates this value during outdoor running or trail running sessions that last at least 10 minutes with a heart rate of at least 75 percent of your maximum. You can view your current VO2 Max level and its historical trends within the Workout Status app on the device.
