I am a 50 year old male whose fitness age on my Garmin Connect app when I got the watch was 47.5 and the achievable fitness age according to the Garmin Connect app was 43.5. Last week, the app told me that I had achieved the achievable fitness age. This morning, my Venue 2 Plus highlighted that my fitness age had further declined to 42. BUT when I went in the app, my fitness age had been reset to 47.5. Can anyone at Garmin tell me why this happened?
