I Got My VO2Max Tested in a Lab to See Which of These Nine Fitness Devices Was Most Accurate

I got my VO2max tested in an exercise lab, and compared that number to the VO2max or cardio fitness scores from Apple, Coros, Fitbit, Garmin, Oura, Suunto, Ultrahuman, Withings, and Whoop devices. I wasn’t surprised that Garmin scored well, but I was expecting better from some of the other brands, like Apple.
