I have been a Fitness instructor for 23 years and a certified Personal Trainer for 20. I am always looking for ways for my clients to get their exercise but have fun doing it and Zumba fitness classes certainly qualify. Aqua Zumba takes all the fun of Zumba and puts it in a water environment where you have the extra resistance of water all around you and you bump up the intensity with no added stress to your joints. Another class with less stress to you joints is my Zumba Gold class at the LifeSpan Center, all the fun of a regular Zumba fitness class with none of the jumping. I also have a Zumba Gold Toning class which adds resistance training and toning to a low impact Zumba fitness workout.
