It's not just adults getting into the Zumba fitness trend — classes for kids are popping up all over, too. In fact, chances are there's a Zumbatomic class near you where your offspring can shake and shimmy through 30 minutes of Latin rhythms. Sessions involve warm-ups and breakdowns of commonly used and dance-inspired games. It's fun, and participants say it works. Kelley Cross teaches a class at Rutland's Ultimate Workout studio and has lost 200 pounds with the help of Zumba workouts. It's also been good for her daughter, 9-year-old Alexis, who has primary cilary dyskinesia, a lung disorder requiring regular exercise to open airways and strengthen respiratory muscles. Cross, a Zumbatomic certified instructor, offers classes at hospitals where she and Alexis go for treatment, and said kids of all ages enjoy Zumbatomic. In fact, she's currently got as many as 30 movers and groovers in each class, both girls and boys. — K.L.
