For the over-60 population, you might consider Mixxed Fit. It’s got simple choreography kind of the way Zumba and Jazzercise put their moves to music, but the music is designed to be inspiring with no offensive themes. Two of my friends who teach at churches theca Mixxed Fit because they know they can trust the music and themes.
How about Zumba Gold?
And why not Zumba, by the way? I have people in their 60’s and 70’s in my regular Zumba class. The way I progress moves starts with the simple, low intensity low impact movement first and then progresses.
The other non-Zumba dance formats that I’m certified in aren’t really for the age group you’re targeting. U-Jam is more youthful than Zumba. Bokwa isn’t really dance and the moves are simple and you can put it to just about any music with a steady beat, but I find that it didn’t fly well with the baby boomer population.
