Equinox

Each location of this fabulous chain feels more like a spa than a gym. With Kiehl’s products in the showers and cool, eucalyptus-scented towels near the treadmills, this place will make even the most workout-reluctant eager to hit the weights. Some locations even have a Kids Club run by Citibabes, so you can relax and enjoy the steam rooms and spin classes without getting a babysitter.
