Daily readiness and cardio target

[LBie]

Mine is charge 5. It first started with my cardio targets in the new year. The numbers set to maintain my cardio fitness level is unreasonable high (above 52 to maintain cardio fitness) which is even higher than before when I set to improve my cardio level (above 35). And I noticed the range hasn't changed ever since for a week already. 

Then 2 days ago, I noticed my daily readiness is 100, and it has been staying at "100" since. With my sleep score still being at my average range, I strongly suspect there's something wrong about both daily readiness and cardio target. It seems there's a disconnection and it causes incorrect calculation on daily readiness and cardio target.

Anyone else has the similar issues?

Hello @LBie 

My apologies if you've already reviewed these page on how Cardio Load & Cardio Target Load are calculated (<-- click link) and how the updated Daily Readiness is calculated (<-- click link).

The Cardio Target Load is calculated based on your fitness goal, past week's activities, comparison to the past month activities, and the Daily Readiness score. There is a more detailed explanation in the above link.

Daily Readiness is an indication on how well your body recovered from recent activity. The score is calculated based on sleep, Resting Heart Rate, and Heart Rate Variability data. The Readiness page in the Fitbit app breaks down where you are on each of these factors. With a score of 100, that means your body is well recovered. But it doesn't mean that you have to do an intense workout.

It's likely that your Target was high initially when the feature was first available to you. I had a similar experience. As the algorithm gets more data, the target load should "settle" into more reasonable ranges.

I've had Daily Readiness scores of 100, yet my Cardio Target Load range was on the lower side based on my goal to maintain, my past activities/workouts, my current position on the Cardio Load bar graph. Personally, I tend to look at my position on the Cardio Load bar graph to plan my workouts. So far, this has worked best for me.

Thank you so much for the explanation. It definately answers my question and I learned something new too about how to read the numbers. Thanks again!

You're very welcome, @LBie 

I'm still learning more about the new Cardio Load feature, even though I've been using it when the feature was first launched for the Pixel Watch 3 users.

I believe there's soon going to be a Fitbit blog post about Cardio Load & Cardio Target Load. Hopefully, it will help users understand this feature & how to use it.
