I forgot to wear my watch but exercised can I add it later?

You can manually add walking or running to the Health app on your phone. However, that won't add it to the Activity and Exercise rings on your Watch.

As far as I know there is no way to add a missing exercise, or edit an existing entry. The only provision is to delete incorrect records entirely, so if I borrowed your watch to run a marathon you could remove it when I handed the watch back to you. Apart from that, you probably have no real idea how much energy you spent on shoveling snow, so how do you add the correct values?

The short answer is yes but many people consider this cheating.

Here is how to do it;

Exercise ring and Move ring;

All you need to do is wear the Apple Watch on your

wrist and launch the Workout app.

Scroll down until you find the ‘Other – Open Goal’

workout. Tap on it.

Once this workout starts you can continue doing

whatever you want, whether its sitting on a couch

watching your favourite TV show or doing dishes.

As the workout time progresses your watch will start

counting calories you have ‘burned’. While calories will

help you close the Move goal, the time you keep the

fake workout running will help you close the Exercise

ring.

Once you are done simply finish the workout, you will

notice that the rings have closed or the calories you

didn’t burn have been added to your daily log.

No, confirming I don’t think it is possible to manually create an entirely new record. I think fieryjack is mistaken.

Glad it helped.
