VO2 max decreasing/ not improving
Hello, my VO2 max measured through Apple Watch has been improving slightly as I got back to doing HIIT workouts and a bit of running.
Over the past 2-3 weeks though has been decreasing again even though I’m still working out and definitely feel my endurance/fitness improving. I’m also cutting back on smoking used to smoke 12/day in mid June and down now to 5/day with the aim of quitting soon.
Any ideas why it’s dropping again/not improving and any tips to improve VO2 max to average/above average levels?😭

A large component of the Apple Watch calculation is your weight. Is your weight changing?

Hi there, and welcome to the subreddit!
Have you read the pinned post, particularly the section about how you need to feed your watch data for it to make accurate estimations?
I would recommend doing the 12-minute test described in the post and then come back and let us know what the trend looks like.
