Help with Apple watch

I think you need to go to your gym with your phone the first time. Get the phone to connect to the gym's wifi, then make sure your watch is connected to your phone. After that, your watch should remember the wifi connection and connect to it even if you don't have your phone. I don't know if Spotify streams music with just the watch. You may have to switch to Apple Music, or use iTunes playlist to copy music to the watch if you want to listen to music without your phone.

 

You can't stream Spotify on the watch unfortunately (you can pre-load downloaded Apple Music playlists if you'd like)

Also, I highly doubt the wifi solution mentioned above would work consistently. I don't think the Apple Watch has the stand alone features you're looking for.

 

I would just focus more on working out for that 1 hour you're there.
