No genre of music generates giggles quite like polka. But while many see polka as the soundtrack for lederhosen-wearing seniors, The Intermittent Health and Fitness Club sees it as a life-changing force. First jump on one foot twice, then hop on the other foot twice. Read a book and repeat again and again. See? It's fun! The IHAF hosts a free polka party inside King's Books. It's going to be polkadelic.
