I've always avoided these but I'm doing more intensive exercise and would appreciate tracking heart rate more closely.
Also if any trackers track and recommend recovery / effort type things. I know Whoop does but it seems a bit out of my price range and more for a real athlete. Also far too much of an input relationship than I think I've time for.
I'm on tamoxifen following breast cancer, sometimes I have weeks when I'm very fatigued. Others when im really quite energetic. I'm also trying to improve vo2 max. Sometimes getting some palpitations which I think is menopause related.
I'm asthmatic and on thyroxine. Bonus if it can track physical anxiety things! (Which I think impact fatigue more than I realise.)
I have a water rower with a Bluetooth plug in and the free version of Strava.
Some threads here seemed to indicate that fit bits aren't as good as they used to be. Garmin website had me muddled they've so much!
