404 Lafayette Street (and one other location)
If you can’t get to India, the least you can do is walk over to Lafayette Street. The city’s largest yoga center, Jivamukti offers at least ten vinyasa/hatha classes a day; teachers are dynamic, music is original, the overall experience energetic yet oddly relaxing. (Beginners beware of open classes).
55 Christopher Street
Yes, yoga sounds weird, but everyone is into it, so you’d like to check it out. At this new pink-painted studio in Greenwich Village, you’ll find a broad mix of hatha classes, special events like a laughing-therapy workshop, and unintimidating classes for "absolute" beginners.
The Sports Club LA
330 East 61st Street (and two other locations)
Can’t take the go-go gym energy any more? Yoga teachers cannot live by asana alone, and now more than ever they’re making their living at gyms here, experts lead the great treadmilled in ashtanga, hatha, kundalini, and a yoga-Pilates hybrid.
Bikram Yoga NYC
797 Eighth Avenue (and two other locations)
Only Californians could think this up "bikram" yoga, which only recently hit our Coast, involves cranking the heat up to at least 100 degrees in airtight studios; you'll come out pure but smelly.
Pantajali Yoga Shala
430 Broome Street
One word: Madonna. The Material Mom may prefer house calls, but devotees of her favorite style Mysore ashtanga practice at the SoHo satellite of the Mysore, India ashram. (Classes sold in sets of 12; curiosity-seekers not welcome.)
