Take a breather

We can all loosen up a little next weekend—and for free. As part of its first annual "Keeping the Space" benefit, yoga studio The Breathing Project (15 W 26th St between Broadway and Sixth Ave) is hosting an open house November 17--19. Sick of downward-dogs? You're in luck: The center will offer 45-minute classes in meditation, tai chi and all kinds of yoga (including prenatal, vinyasa and restorative varieties) for what's promising to be a pretty varied weekend of mental and bodily contortions.
