Walk into an American studio and the class on the schedule might be called Vinyasa, Power, Hatha, Ashtanga, Iyengar, Hot Yoga, or something else entirely. The names make them sound like separate traditions. They aren't, at least not completely. Follow most of them back far enough and you end up in a surprisingly small number of places in India, and with a surprisingly small number of teachers. The interesting part is not only who those teachers were, but who studied with them, who brought the teaching to the United States, and what happened to it once it got here. That is what this map is about.
There wasn't one moment when yoga arrived in America. It came in waves, and what each wave carried was quite different from the last. The first, from 1893, is philosophical — Vedanta, meditation, the Yoga Sutras, almost no postures. The second, from the late 1940s, is physical: hatha yoga as exercise, taught by a Latvian-Russian woman in Hollywood and then broadcast on public television. Then came the gurus. From the mid-1960s they arrived in person, founded ashrams, ordained American successors and built institutions meant to outlive them. Several did, badly. The very first instruction on American soil belongs to none of the three, and is covered in the note at the end of section II.
Immigration policy is an important part of this story too. United States v. Bhagat Singh Thind (1923) held that Indians were not eligible for naturalization, and the Immigration Act of 1924 made immigration from Asia more restrictive still. The Luce–Celler Act reopened the door in 1946; the Immigration and Nationality Act of 1965 removed the national-origins quota system altogether.
So the gap between the early twentieth century and the explosion of the 1960s wasn't a matter of Americans losing interest. The legal environment had changed.
American yoga looks much more complicated than it actually is. There are dozens of names on a modern studio schedule, and a large share of them trace back to three teachers working in India in the middle of the twentieth century: Krishnamacharya in Mysore, Sivananda in Rishikesh, Bishnu Charan Ghosh in Calcutta. Alongside those three sits a fourth category — teachers who reached America through independent devotional and meditation movements rather than through a posture system.
The distinction matters, because these were not three branches of the same school. The three centers sit roughly two thousand kilometers apart, in three different language regions, and the men who ran them were not colleagues, not students of one another, not part of any shared movement. Their students carried very different approaches abroad, where they were adapted again. What Americans eventually came to call simply "yoga" was assembled out of several unrelated projects.
Not everything fits neatly into the three Indian centers. The independent traditions have their own histories, and should not simply be folded into the three posture-based interpretations.
Simplified. Several American schools (Kripalu, Anusara, Jivamukti, Forrest) draw on more than one root, and a few — Yin above all — come from outside this genealogy entirely.
There is an important complication here. Pierre Bernard was teaching posture practice in the United States as early as the 1890s, and by 1918 he was running a substantial yoga estate in Nyack — three decades before the second wave that this page, like most accounts, treats as the moment yoga became physical here. In chronology, size, money and visibility it would be reasonable to call him one of the earliest major American yoga figures. So why isn't he one of the roots on the diagram?
Because being early isn't quite the same thing as establishing a tradition. Clarkstown was essentially a private institution. It trained no teachers to send out, published almost nothing until his nephew's book in 1943, and dissolved when he died in 1955. Mysore and Rishikesh were smaller operations in most respects, and they propagated because they did the one thing Nyack never did: they sent students away with instructions to teach.
That distinction turns out to be important. A tradition isn't simply a body of knowledge passed from one person to another. It needs some mechanism for passing that knowledge on — and a rich, famous, well-attended school without one leaves less behind than a modest school that has it.
Bernard's influence didn't disappear completely. It moved sideways rather than down. Ida Rolf carried things she had learned at Clarkstown into Rolfing; Ruth Fuller Everett carried her experience into American Zen; Bernard's wife Blanche DeVries ran studios in Manhattan teaching women, which is the format the entire field now runs on — not the ashram, not the country club. So Bernard belongs in the history. He just doesn't fit neatly into a succession chart, and drawing him into one would be the same error as the claimed links in section V.
Each entry gives the founder, how the method reached America, and — the part that is hardest to find anywhere else — who actually carries it today. Succession is the live question in this field right now: several of the largest traditions have no named heir, and several others are governed by teacher boards rather than a person.
The most significant development in American yoga since roughly 2005 is not a new posture style. It is a shift in who the practice is understood to be for, and it has produced its own line of teachers — most of them women, many of them working outside the studio economy entirely.
Grew out of the Krishnamacharya–Desikachar line, where practice was always prescribed one-to-one. Gary Kraftsow founded the American Viniyoga Institute in 1999 and remains its director. The International Association of Yoga Therapists now accredits training programs and certifies C-IAYT practitioners — the field's only real clinical credential.
David Emerson developed TCTSY with psychiatrist Bessel van der Kolk at the Trauma Center in Brookline, Massachusetts. Since 2018 it has been housed at the Center for Trauma and Embodiment at the Justice Resource Institute, co-led by Emerson and Jenn Turner. It is an evidence-based adjunctive treatment for complex PTSD, not a class style.
Matthew Sanford, paralyzed at 13, founded Mind Body Solutions and made the case that a body that cannot move still has a mind–body relationship worth practicing. Jivana Heyman founded Accessible Yoga in Santa Barbara — teacher training in 2007, the conference in 2015, and the online Accessible Yoga School in 2020 with Amber Karnes.
Nikki Myers built Y12SR by fusing the twelve-step framework with yoga practice and somatic work, on the premise that addiction is a disease of disconnection. Meetings run nationally; she still leads teacher trainings, including through Kripalu.
Judith Hanson Lasater — a founding board member of Yoga Journal in 1975 and a student of Iyengar's from 1974 — codified restorative yoga from his prop work. Tracee Stanley carries yoga nidra from the Himalayan/Sri Vidya tradition; Richard Miller's iRest adapted nidra for veterans and clinical settings.
Susanna Barkataki (Ignite Institute), Michelle Cassandra Johnson (Skill in Action), Dianne Bondy (Yoga For All), Jessamyn Stanley (The Underbelly), Octavia Raheem and Rina Deshpande have reframed the central question from which style to whose practice, taught by whom, and on what terms. Yoga Alliance made an equity course mandatory for registered teachers in 2020.
You cannot draw an accurate map of who inherited what without this. In transmission traditions the guru's authority is the transmission mechanism, so a finding against a founder is not a side note — it is the event that determines whether a school splits, dissolves, renames itself, or carries on unchanged. What follows is the documented record, kept short. It runs earlier than the coverage suggests: the first entry is from 1910.
Less than the volume of coverage suggests, and more than nothing. Yoga Alliance issued a Code of Conduct and Scope of Practice in February 2020, made an equity course mandatory, and rebuilt the 200-hour standard — but it remains a voluntary registry with weak power to remove anyone, and schools tied to documented misconduct stayed listed for years. The durable changes came from below: consent cards, hands-off-by-default adjustment norms, trauma-informed cueing, and a generation of teachers who decline to organize a school around a single infallible figure at all.
What the words on a class listing actually mean, and which interpretation each one comes from.
| On the schedule | Descends from | What you are actually getting |
|---|---|---|
| Vinyasa / Flow | Mysore | Ashtanga's breath-linked movement, freed from its fixed sequence. The default American class. Quality varies more than in any other category, because the format has no governing standard. |
| Power | Mysore | Vinyasa with the Sanskrit and the chanting stripped out for a gym audience — Bryan Kest and Beryl Bender Birch coined it independently around 1995. Faster, hotter, fitness-framed. |
| Ashtanga / Mysore | Mysore | The fixed series, memorized. "Mysore style" means you practice your own sequence at your own pace in a room with a teacher circulating — not a led class. Demanding, and the closest thing to an apprenticeship. |
| Iyengar | Mysore | Props, long holds, precise alignment, and the only style whose teachers hold a graded certification assessed by the founding family. Look for "CIYT" — it means something. |
| Hatha | Rishikesh (usually) | A catch-all. In practice: a slower class with held postures and no continuous flow, usually descending from Sivananda or Integral Yoga. |
| Hot 26 / 26+2 | Calcutta | Bikram's sequence, 105°F, same twenty-six postures and two breathing exercises every time, generally under a name that is no longer his. |
| Yin | Outside the genealogy | Long passive floor holds, three to five minutes, targeting connective tissue. Taoist and Chinese-medicine framing rather than Indian. A different practice wearing the same word. |
| Restorative | Mysore, via Iyengar | Fully supported postures held for very long periods. Nothing is stretched on purpose. Judith Hanson Lasater's codification of Iyengar's prop work. |
| Kundalini | Independent | Repetitive kriyas, vigorous breathwork, mantra, often white clothing. A distinct technology with a distinct history — read the reckoning section before enrolling in a training. |
| Yoga Nidra | Rishikesh | Guided practice done lying down, no postures at all. From Satyananda's Bihar School; iRest is the clinical adaptation. |
| Rocket | Mysore | Larry Schultz's reshuffling of Ashtanga's series, developed in San Francisco in the 1990s. Playful, inversion-heavy, "because it gets you there faster." |
| Baptiste / Journey Into Power | Mysore + American | Baron Baptiste's heated, sequenced power yoga with a strong personal-transformation frame. Highly systematized teacher training. |
| Viniyoga / Yoga Therapy | Mysore | Breath-led, adapted to the individual, often one-to-one. If a teacher lists C-IAYT, they hold the field's clinical credential. |
| Jivamukti | Mysore + devotional | Vigorous vinyasa with scripture study, chanting, music and an explicit ethical vegan commitment. A monthly theme is set centrally. |
| Forrest | American-born | Long holds, intense abdominal work, heat, and an emotional-release orientation. Built by Ana Forrest for trauma and addiction recovery. |
Northern California is not incidental to this story. A surprising share of the American infrastructure — the first studio, the magazine, the teacher-training economy, several of the styles — was built within an hour of San Francisco.
