You can find a bunch of different workout stations here: https://www.pandora.com/browse/music/activities/workout
And if you search for "workout" on Premium you can find playlists with Workout in the title, like Gym Workout Hits.
@Roxy It's great to have you participating in the community!
Personally, my workout playlist is 2000's Hip-Hop; but that is also particular to my taste in music. The type of music you're looking for may be dependent on your taste in music as well as the types of workouts you're doing as @JackPhantom shared.
I hope that helps get you moving and grooving during your workouts!
