Accidentally deleted this app from my watch. How do I redownload it to my watch?

Apple Support's article: Delete apps from your Apple Watch - Apple Support

says:

"If you want to restore an app, including built-in Apple apps, you can download it from the App Store on your iPhone or Apple Watch"

Here's the App Store Preview Page for the Watch /workout App:

Hi Mygooddog3,

welcome to the Apple (user-to-user) Ciommunity.

As your question raises quite a different topic, it is best to start a new discussion. Just click "Ask the Community" at the top of this discussion page. (Please include your Watch model, and Watch OS version so Community members can help troubleshoot.)

Cheers :-)
