My cardiac fitness score is something I’ve been very proud of. I started the day with a score of 62, but after my workout it dropped down to a 51 & I have no idea why. Has anyone else had this issue?

Hi @FrankieJ3, welcome to the Community Forums.

 

Thanks for bringing this to our attention and for the details that were shared in your post. Your cardio fitness score is determined by your resting heart rate, age, gender, weight, and other personal information. For best results, make sure your weight is correct in your Fitbit profile. Also, wear your tracker or watch to sleep for a better resting heart rate estimate. Your cardio fitness score will be shown as a range unless you use GPS for runs. For more information, please review the details that are specified on: What is my cardio fitness score?

 

I'll be around if you need anything else.

I appreciate the info very much but I sleep with my watch on every night & I have a Fitbit Aria that logs my weight for me. My score went from a 62 to a 51 in an hour. I’m in the best shape of my life right now & am working out/exercising almost 20 hrs a week, every week. I just don’t understand what happened.
