I have been working out with Jazzercise for 27 years and I highly recommend it. The music is current and upbeat. The dance routines are choreographed to the songs, and the sets they are in change each class. Its always fresh and never boring. Classes are an hour: typically 45 minutes of aerobics and the last 15 mins focus on arms, abs, legs. Its a full body workout every time you go! The community of people are regulars because once you get into it, its too much fun to stop doing. A very supportive group. The instructors are fantastic. Every single time I go, I am glad I did. Its an hour to let go and have fun - and be healthier for it. Try it!
