Modern styles, explained plainly

Style names in a class schedule are brands and methods, not chapters of the Vedas. They are still worth sorting out, because the wrong room is a bad way to start.
Iyengar yoga holds poses and uses props. The teacher talks about alignment in detail. A beginner can like the clarity and still find the holding long. The method comes through B. K. S. Iyengar, described with Krishnamacharya’s other students in the previous article.
Ashtanga, in a schedule, almost always means Pattabhi Jois’s set series, moving with the breath. It is athletic. It shares a Sanskrit word with Patanjali’s eight limbs and is not the same thing. If you want the limbs, read them. If you want the series, that is a different class, and it is a hard first week.
Vinyasa is a looser modern word. It usually means poses linked to breath, with a teacher who designs the sequence rather than repeating one fixed series. Two vinyasa classes can differ more than two Iyengar classes. The glossary says the routines on this site are slower than a typical vinyasa class. That is a choice about pacing, not a claim that vinyasa is illegitimate.
Restorative yoga uses supports so the pose is rest, not effort. Blankets and bolsters do the holding. Yin yoga, associated in the late twentieth century with long passive holds and with teachers such as Paul Grilley, stays down for minutes. Yin and restorative look similar from the doorway and are taught with different aims. This site’s sleep routines lean toward rest. They are short, and they are not a full yin syllabus.
Hot yoga is taught in a heated room. The best-known fixed series is the one associated with Bikram Choudhury: the same postures in the same order, in heat. Heat changes the risk. The National Center for Complementary and Integrative Health tells newcomers to avoid extreme practices and notes hot yoga as an added strain. None of the routines here are heated. You can decline a hot room without falling behind a tradition.
“Hatha,” on a gym schedule, usually means a gentler class that holds poses. Historically, hatha manuals were more severe than that label now suggests. The word has stretched. Ask what the hour contains.
This site is beginner instruction in English: 44 poses, a 7-day path, and short timers. It is closest to a slow hatha hour and identical to none of the brands above. Mark Singleton’s Yoga Body is the scholarly argument that this kind of posture practice has a modern history. You do not have to accept every page of that book to stop calling a ten-minute desk break an ancient rite.
