The Niantic Jazzercise group is located up the hill from the Bridal Mall across from Rocky Neck State Park. It can be a bit hard to find, so look for building C at 11 Freedom Way, around to the back. The Jazzercise dance fitness program was founded in 1969 by Judi Sheppard Missett and has turned into a very successful international franchise with more than 7,800 instructors teaching in 32 countries. It involves a 60-minute workout with a fusion of jazz dance, resistance training, pilates, yoga and cardio box movements.
