Does anyone else have an Apple Watch and/or iPhone that is reporting a very low VO2 max? I've never had mine tested and I haven't been running much lately, but a year or two ago I used to run 8 miles three times a week, so my cardiovascular fitness should be ok. However, my watch is reporting that my VO2 max estimate is 32.4 mL/(kg*min) which (for a 25 year old male) is very poor. I have a hard time believing my VO2 max could be that bad. I do have bad allergies and my heart rate naturally sits a bit higher than most, so I'm wondering if that is throwing it off or if I should be concerned.
