I used to take part in jazzercise classes. I don't hear about them anymore. Now it's about pilates, yoga, hip hop and line dancing. Jazzercise was lively and more fun. With the exception of hip hop and line dancing I think I would fall asleep. Too old for hip hop and there's only so much you can do in line dancing - to the left; to the left; to the left, right, left. Is anyone still doing jazzercises out there?
Jazzercise has been replaced by Zumba, you should try it, your never to old and many classes are not just 100% Latin music. The class I take has quite a bit of hip hop and modern dance routines worked in, it is low impact BUT high cardio so you get quite the workout. The beauty is that you do not have to go hard if you are not in shape, you do the moves you can and build up as you get stronger. Check your local papers for classes, the price is not that expensive. I found coupons thru Groupon for some classes in my area.
