Yoga Union brings together the two major threads of yoga practice today: structural and flow. Owner and director Alison West provides an expert foundation in anatomy and kinesiology, while a roster of highly trained teachers provide caring and precise instruction in daily structural and flow classes. The studio often hosts community events and workshops with internationally known teachers. The space is warm and airy, with large windows looking onto the brownstones and skyscrapers of Chelsea and the Flatiron District. Each room has a professionally-designed ropes wall and Jade yoga mats.
