Maiden Lane Studios
80 Maiden Ln., Union Square
While we're partial to this airy space because it’s set up mere steps from our San Francisco goop MRKT, the semi-private, private, and group class menu, which ranges from Pilates to barre to yoga, really is one of the best in town. They also offer one-on-one fascial stretch therapy—pretty game changing for anyone discovering the joys of fascia.
