Watching TV and ordering in won't help you recover from that lingering New Year's hangover, but it's not too late to make a resolution to get into shape. If you've never taken a yoga class, give the rediscovered seventies craze a try; if you're already in on the secret, maybe you need a little motivation. Either way, here's a can't-miss deal: The following yoga centers are giving New York readers one free class between now and February 28 (note that several require reservations -- mention "Sales & Bargains" when booking). Sign up according to your ability, and surrender this page when you arrive. Happy stretching . . .(Note: Bring only the S&B page from the MAGAZINE; print-outs of this web page will NOT be honored.)
* Soho Sanctuary teaches three kinds of yoga (Hatha is the least taxing, Vinyasa the most) and is also a full-service spa with lots of all-natural treatments. A eucalyptus-scented steam bath is free for anyone who takes a class. The "S&B" deal is not valid for the 6 and 7:15 p.m. classes Tuesday through Friday. Call to reserve. 119 Mercer St. (212-334-5550).
* Jivamukti Yoga Center has a trademarked style that's sweaty, calorie-consuming, and rumored to be addictive (to celebrities like Elizabeth Berkley and Sting as well as regular humans). A post-workout massage may be in order ($75 for an hour). (This offer is good only on weekdays before 5 p.m. or after 7:30 p.m.) Call to reserve. 404 Lafayette St. (212-353-0214).
* Integral Yoga Institute pushes a total yoga lifestyle: The larger, West Village branch has a whopping seven studios (classes teach proper breathing and postures), a vegetarian food shop, and stress management workshops. The "S&B" deal is for new students only. No reservations. 227 W. 13th St. (212-929-0586); 200 W. 72nd St. (212-721-4000).
* Om Yoga Center teaches vigorous, flowing Vinyasa-style yoga in two bright, homey studios. The center is cozy, attitude-free, and good for all levels. No need to reserve; just come fifteen minutes before the class starts. 135 W. 14th St., second floor (212-229-0267).
* Bikram Yoga College of India increases strength and stamina. The studio is kept very warm to promote flexibility (you'll learn to hold certain postures for a full minute). If you like it here, you're in luck -- the second class is always free. No reservations; arrive fifteen minutes early. 797 Eighth Ave., near 48th St., fourth floor (212-245-2525).
* Yoga Zone brought yoga to the masses with a TV show, videos, and a product catalogue -- but the two Manhattan studios still teach posture-based Hatha. This offer's not good Monday through Thursday 5:45 to 8 p.m. or Saturdays 10:30 a.m. to noon. No reservations. 138 Fifth Ave., near 18th St. (212-647-yoga); 160 E. 56th St. (212-935-yoga).
