The Woburn Rec Department is a great resource for residents in all seasons for children, families and adults. This winter why not take advantage of some of the classes they offer to beat the cold and get some exercise. Register today for adult fitness classes such as yoga, barre and zumba or children's fitness classes like karate, zumbini, dance and yoga. There's even a kids painting class on the schedule in February. Classes begin in January and go through February or March depending on the class.
