I started going to the Jazzercise studio when I purchased a Fitness passport from Groupon which included 10 free classes at this location. I started with Jazzercise and participated in 2 classes, when one of the instructors mentioned the Strength classes. I had been having a little difficulty following the fast paced class, but still had fun. She said the Strength classes would be easier to follow along with and she was right. I still can't balance very well on the large ball, but I've gotten better with each try! I look forward to taking more of these classes. All the instructors have been very good!
