Zumba classes are coming to a gym that I work at. And i know of a few instructors who've done the training for it.

From a fitness leaders perspective latin moves can be quite quick moving, thus getting the heart rate up - which is great.

The only downside I can see is that its 'ALL' latin - no variation. You'll have you mambo's, samba's, chasay's, butt and hip wriggling and who knows maybe even a shimmy! I'm sure they'll make you pivot, spin you around use different armlines - but there is only so much you can do with it once you've mastered it.

I'm a Body Jam instructor, so I guess I prefer having a few tracks (3 or 4) of latin in the class, as opposed to having the whole class latin - probably because I'm a big fan and love the R'n'B / Hip Hop style dance - So I may be biased there . I've always found latin is a bit harder to instruct - who knows, it could be because I favour the other style of dance - but I am mindful my class participants deserve the best latin tracks I can offer, but in general it can be harder to pick up for them on a whole. However, practice makes perfect!

I just watched a demo online and it looks fun too!

Let me know how you go!
