Why is the daily workout suggestion to rest?

How’s your sleep?  Usually when I have a poor sleep night it suggests that I do a recovery run or rest.

When I tried to use the daily suggestions I remember that I sometimes got Rest as a preparation for a harder workout that was coming. You can press one of the buttons (don't remember which) when the suggestion is shown to get more details about the suggestion.

It uses: 

• Training Status

• Training load and load focus

• VO2 max value

• Recovery time

• Sleep data

• Profile of recently performed workouts

Non Running (Cycling) activities aren't used, however as they can impact stress and hence recovery, they would be factored into the determination.

So would suggest reviewing the above factors and perhaps it may suggest a reason as to why it suggested the rest day.....

Also worth adding, in my experience (as a cyclist) if you ignore a recommendation to have a "rest" day and do even light exercise the watch will keep nagging you (well, me) day after day to have a rest day. Since I almost never ride for less than an hour, even if cruising easily, it seems it's too much for the watch to tolerate. I've been told to rest every single day for more than a week, in the past. Until I actually take a day off it's like groundhog day over and over.

Just noticed that although today's workout suggestion is rest, the training status widget tells me: "to make your status productive, try working out longer or more often". Seems the two are not correlated all that well?

Daily suggestion is short-term, here and now. Training status has a longer perspective.

In your case following the daily suggestions for a couple of weeks will also fulfil the training status suggestion even though rest is on the agenda for today. 

Don't forget that daily suggested workout takes the following into account as to how it determines your workout:

• Training Status

• Training load and load focus

• VO2 max value

• Recovery time

• Sleep data

• Profile of recently performed workout

So if your sleep was bad, you could very well see a base/recovery run - something less intense, despite the long term goal being to workout longer. Technically giving you a recovery/base run is covering more often, as perhaps it should be more of a rest day? Difficult to tell/suggest why it determined what it did without knowing your other metrics.

If you haven't read these support articles on it, would suggest doing so - they are a great read:

Think I found it; my HRM strap broke during one of my runs in the past week (it had recorded far too high a rate). This must have messed up the metrics.

I use the workout suggestions only as a way to check if the planned workout type on my regular training plan matches with the day's suggestion (base, tempo, threshold, .. ). It almost always matches. Only this time it was surprisingly off, and that must have been due to the workout with the wrong HR data.
