New York Pilates
With multiple locations and plenty of class offerings, you might not get stuck on a waitlist when booking a class at New York Pilates, but you'll still be surrounded by an elite crowd of cool girls and influencers in their sleek one-piece bodysuits whenever you check in. The beloved reformer Pilates class founded by fellow cool girl Heather Andersen offers small classes and one-on-one training (to converts including Ashley Olsen) in an Insta-worthy environment - that promises an Insta-worthy ass. No wonder the influencer set loves it so much.
