Ashtanga Yoga. Husband-and-wife team David Kyle and Elizabeth Sallaberry found the hot, humid climate of Puerto Rico perfect for practicing and teaching ashtanga vinyasa yoga, one of the more vigorous styles. Their friendly studio, which has a large local following, offers classes ranging from beginner to advanced (most are held in English), as well as workshops from internationally renowned instructors. Be prepared to sweat, as the studio is intentionally not air-conditioned, although there are ceiling fans. The rate is $19 for a drop-in class; mat and/or towel rental is an additional $3 to $5. 1950 Av. McLeary, Ocean Park, San Juan, n/a Puerto Rico, 00911. 787/677–7585;
