Flex Studios is one of my favorite places and workouts in NYC. This pilates based workout challenges me every time, even after 4 years! Instructors are warm, caring, and know their anatomy and physiology. I am a physician and am always beyond impressed with the level of knowledge of the human body of each instructor and attention to detail and form. If you're looking for a "scene" or "easy workout," this is not it. What you will find is genuine people who want to teach and fellow class go-ers who want to work hard. After having moved to the west coast, Flex Studios is one of the biggest things I miss - workout wise and people wise! Flex Studios is a very special place.
