Enough hibernating. Spring has sprung, which means it’s time to get out and get fit! Manhattan Plaza Health Club, one of New York City’s hottest gyms, is here to help. This 6-month membership includes access to top-of-the-line weight training equipment, a sunlit cardio mezzanine, and unlimited classes.  You will also enjoy the facility’s gorgeous indoor swimming pool and world-class climbing gym.  Plus, it’s right across the street from Playwrights Horizons, so you can collapse in a theater seat after you hit the gym.
