My personal trainer is getting her new studio, Joining Active Bodies Studio, up and running in Mattituck. She currently does Zumba several nights a week, and will be adding other classes like kickboxing, TRX, bosou (sp?) and spinning. If you're on FB, you can like her fan page, http://www.facebook.com/pages/JABS-Joining-Active-Bodies-Studio/115228075223313,
and get scheduling info.
