For an equally exclusive experience with more of a zen vibe, the ness is an invite-only studio offering super-intimate cardio bounce and strength classes in Soho. With no more than 12 people to a class, instructors are able to give you all the attention you need in an environment that welcomes community-building. Gwyneth Paltrow is already a fan - need we say more?
