Core Flex is a neighborhood Pilates Studio in the heart of Chelsea. We set out to create a simple, clean and elegant space for you to exercise, relax and socialize. Something that feels different from other gyms and fitness studios.

Our group classes are limited to seven people, providing hands on semi private instruction in a spacious and bright environment.

Using state-of-the-art Rialto Reformers all the way from California we focus on core strength and full body flexibility, delivering a unique fusion of traditional pilates and dynamic strength training.


 Each of our small group, strength training sessions are led by experienced instructors, in a beautiful modern space. Giving you that hands on personal touch.


Your core is the support system to the spine. Our sessions use intelligently designed spring based resistance training to sculpt lean and long bodies that are strong to the core.


Spring based resistance rather than weights simultaneously builds length and strength in the muscles. We include stretches in every workout to lengthen and tone.
