In one breath

Ashtanga yoga set beside the styles it is most often confused with, on pace, on what a class contains, on who it suits and on what is genuinely hard about it. The classes here are not labelled by style, so this page is written to help you read a timetable rather than to sell you a label.

The one sentence definition

Ashtanga yoga, in its modern form, is a vigorous system in which the same fixed sequence of postures is practised in the same order every session, each posture linked to the next by a set movement on the breath, traditionally six mornings a week.

Two clarifications, because the word carries two meanings and the confusion is constant. Ashtanga in Patanjali's Yoga Sutras means the eight limbs, the whole eightfold path of yoga, of which posture is one limb. Ashtanga as a class on a timetable means the physical system taught in Mysore by Pattabhi Jois through the second half of the twentieth century. The second meaning is what this page is about, and the school itself takes its name from the first.

What makes it unlike almost every other class you can attend is that the sequence does not change. You do not arrive wondering what today will be. That fixedness is either the best or the worst thing about it depending entirely on your temperament, and there is very little middle ground among the people who try it.

The primary series, and what a session contains

The first sequence, the primary series, is called Yoga Chikitsa, meaning yoga therapy. A full led primary series takes about ninety minutes and runs in a fixed order.

  • Opening. A short chant, then five rounds of one form of Surya Namaskar and five of a second, longer form. That alone is more sun salutation than most classes contain in total.
  • Standing sequence. Forward bends, triangle variations, twists and one legged balances, in an unvarying order, five breaths each.
  • Seated sequence. The long middle of the practice, dominated by forward bends, with a linking vinyasa of plank, lowering, upward dog and downward dog performed between almost every posture. This is where the repetition load on the shoulders comes from.
  • Finishing sequence. Backbending, then shoulderstand and headstand work, then a seated close and a long rest.

The linking vinyasa is the defining feature and the one nobody warns beginners about. Performed between the seated postures, it can mean lowering from plank forty or more times in a session. That is a serious amount of repeated shoulder work, more than most upper body training sessions contain, and it is the source of a large share of the injuries this system is known for.

Mysore style, which is the part worth knowing about

Most ashtanga is not taught by a teacher at the front demonstrating. It is taught Mysore style, which is the most interesting teaching format in modern yoga and is badly explained almost everywhere.

In a Mysore room, everybody practises the same sequence but each person is at a different point in it, moving at their own pace, in silence. The teacher walks between mats, adjusting one person, giving another the next posture, holding a third back. You are given new postures one at a time, when the teacher judges you ready, and not before. A beginner might spend the first weeks doing only the sun salutations and the closing postures, which takes twenty five minutes, and that is a complete practice for that person at that time.

This is, structurally, a very good way to teach, and it is much closer to how yoga was historically transmitted than a led class is. It also produces something rare: practitioners who genuinely know their own practice and can do it alone in a hotel room, because they have never once followed anybody. Whatever my reservations about the physical demands of the system, the Mysore format is the thing I would steal from it if I were designing a school from scratch.

How hard it is, honestly, and the injury question

Very hard, physically, and this should be said plainly rather than softened. The pace, the heat and the repeated weight bearing put it well above the intensity of a slow held practice. Measured energy cost in traditional hatha postures mostly sits between one and two metabolic equivalents, which is gentle activity; flowing practice of the ashtanga type sits in the range that counts as moderate intensity exercise, and a full primary series is a substantial workout by any definition.

The injury record is the honest reservation. The main patterns are hamstring attachment strain from the volume of deep forward bending, shoulder trouble from the repeated lowering, wrist pain from the load, and lower back irritation from the deep backbends late in the sequence. None of this is inevitable, and much of it comes from two features of the culture rather than the postures: the traditional reluctance to use props, and the pressure to progress through the series. A good teacher removes both of those problems. A poor one amplifies them.

Research on the system is thin and mostly small. A randomised trial of a twelve week Ashtanga Vinyasa programme in Portuguese air force trainee pilots reported within group improvements in general health, grip strength and lung function measures, which is worth knowing and is a small study of a specific population. It is not a basis for claiming this style is better than any other, and I would be cautious of anybody who tells you it is.

Which should I pick

This is the style with the clearest yes and no answers of any on this site.

  • You like structure, repetition and measurable progress, and you already have a strong body. Ashtanga, Mysore style, with a teacher who lets you take years over the series.
  • You travel and want a practice you can do anywhere without a video. Ashtanga. Nothing else gives you this as reliably.
  • You are over fifty, stiff, or coming back to movement. Not ashtanga, or not yet. Start with a held practice and consider it in a year if you still want to.
  • You have a shoulder, wrist, hamstring or lower back problem. Not ashtanga. The volume of loading in the linking movements is the specific issue.
  • You want variety, or you get bored easily. Not ashtanga. The sequence never changes and that is the point.
  • You want the fitness without the risk profile. A led vinyasa class with a teacher who corrects, or hatha plus running. See hatha vs vinyasa for that comparison.

My verdict. I admire this system and I would not send most of my students to it. What I admire is the seriousness, the Mysore teaching format, and the fact that it produces people with a real daily practice rather than a class attendance habit. What I will not defend is a tradition that historically treated props as a weakness and pushed people through a fixed order regardless of the body in front of it, and the pattern of hamstring attachment pain that comes out of rooms like that is well enough known to have given me a settled view about it. If you are twenty five, strong and drawn to it, go. If you are fifty and stiff and drawn to it, go and watch a Mysore room first, then come back to me in a year when you can hold a standing posture for a minute without your knee collapsing inward, and I will tell you honestly whether I think you are ready.

It is not taught here, and what happens instead

Ashtanga is not taught here. The classes here are not labelled by style at all: the hour covers asana, pranayama and relaxation, taught slowly, and there is no Mysore room, no set series and no expectation of a daily attendance.

That means this page cannot sell you anything, which is a good position from which to write about a style. It also means I am describing a system I have watched from outside rather than one I have practised daily. I have taken that into account in what is written above and I would rather say it than let you assume otherwise.

If the appeal of ashtanga for you is the discipline of a fixed daily practice, that is available without the physical risk. A short, unchanging home sequence practised every morning does the same psychological work: the seven day beginner plan is built on exactly that principle, and the Surya Namaskar page gives you the one sequence that ashtanga itself opens with. If it is the intensity you want, that is a different conversation and an honest one to have with a good local ashtanga teacher.

What is actually in the primary series, and what it demands

The primary series is a fixed list, and knowing the first part of it tells you most of what you need to decide.

It opens with five rounds of Surya Namaskar in one form and five in another, which is already more sun salutations than most people have done in a month. Adho Mukha Svanasana appears dozens of times as a transition rather than a pose, Uttanasana and Trikonasana arrive in the standing block, and the seated block is built around Paschimottanasana and its variations. The closing sequence includes Sarvangasana, Halasana, Matsyasana and Sirsasana, in that order, every single time.

That closing list is the reason I am careful about recommending this to anybody over forty or to anyone with a neck. Four of those five appear in the avoid lists on yoga for beginners over 40 and yoga for neck and shoulder pain. The breath used throughout is Ujjayi, and it is the part of the method that transfers usefully to any other class.

Ashtanga yoga compared with the styles it is most often confused with.
What is being comparedAshtanga yogaVinyasa yogaYin yoga
PaceFast and unbroken. A set sequence moved through on the breath, with a linking vinyasa between postures.Continuous, but the sequence changes from class to class at the teacher's discretion.Almost motionless. Four or five shapes fill an hour.
How long you holdFive breaths in most postures, counted out loud in Sanskrit in a led class.One to five breaths, depending on the passage.Three to five minutes in a passive shape.
PropsEssentially none. The tradition expects you to meet the posture as it is, which is its most criticised feature.Rare. There is no time to fetch one.A bolster or block to set the shape, then stillness.
SweatA great deal. Heat is explicitly part of the method, produced by the breath and the pace.Often a lot.None, and you may go cold.
Who it suitsDisciplined, already strong people who want a fixed practice to repeat for years and a clear structure.People who want to move and sweat without committing to one sequence.Stiff hips, and anyone whose flexibility has plateaued.
Injury friendlinessThe lowest of the three. The fixed order, the jumping and the repeated chaturangas load wrists, shoulders and hamstrings heavily.Moderate, and better where a teacher stops to correct.Moderate. Long passive holds can quietly overload a joint.
How it is usually taughtMysore style: everyone in the room practises their own sequence at their own pace, and the teacher moves between them.Led from the front, to music, following the teacher's plan.Led from the front, quietly, with a timer.
What is hard about itThe commitment. Six mornings a week is the traditional expectation, and the first year is genuinely difficult.Holding any alignment once you are breathing hard.Staying with a dull ache for five minutes without negotiating.

If you want to feel the difference rather than read about it, work through Surya Namaskar at the pace this page describes, and then at half that pace. The poses are identical and the practice is not.

From Vaithialingam's class

People who come across from ashtanga tend to arrive with two things: an extraordinary discipline that I could not teach anybody if I tried, and often a complaint at the top of the hamstring or in a shoulder. I have a lot of respect for the first and a settled irritation about the second, because where it happens it usually comes from being moved along the series faster than the body agreed to. When somebody asks me what to do about it, I take away half the postures and give them a block, and they find both of those instructions genuinely difficult, which tells you something about what the training does to a person. I do not think the system is wrong. I think it is unusually unforgiving of a bad teacher.

This is what he sees in class, not a medical claim. Where this page states what a practice does for a condition, the evidence is in the sources cited on the page.

Questions people ask

What is ashtanga yoga in simple terms?

A vigorous system in which the same fixed sequence of postures is practised in the same order every session, with a set linking movement on the breath between postures, traditionally six mornings a week. The first sequence, the primary series, takes about ninety minutes. The word also has an older meaning, the eight limbs of yoga described by Patanjali, which is where the school took its name from.

Is ashtanga yoga good for beginners?

Only in a Mysore style room with a teacher who will give you the first few postures and nothing more. In that setting a beginner practises the sun salutations and the closing sequence for several weeks, which takes about twenty five minutes and is entirely reasonable. A led primary series class is not a beginner class, whatever the timetable says, and walking into one with no experience is how people hurt a hamstring in the first month.

What is the difference between ashtanga and vinyasa?

Ashtanga is one fixed sequence practised in the same order every time. Vinyasa is a broader term for any class that links movement to breath, with the teacher choosing a different sequence each time. Modern vinyasa grew directly out of ashtanga, which is why the shapes look familiar. If the class is different every week, it is vinyasa. If it is identical every week and nobody is calling out what comes next, it is ashtanga. The pace question is set out in full on the hatha versus vinyasa page.

Why does ashtanga have a reputation for injuries?

Three reasons, and only one of them is the postures. The linking movement between seated postures means lowering from plank forty or more times in a session, which is a heavy repeated shoulder load. The volume of deep forward bending strains hamstring attachments. And the tradition has historically been reluctant to use props and quick to move people through the fixed order. A good teacher removes most of the risk by slowing the progression and permitting a block. A poor one does the opposite.

What is mysore style and how is it different?

In a Mysore room everyone practises the same sequence but each at their own point and their own pace, in near silence, while the teacher moves between mats adjusting people and giving out new postures individually. Nobody demonstrates from the front. It produces practitioners who genuinely know their own practice and can do it alone, because they have never followed anybody. It is the most interesting teaching format in modern yoga.

How many days a week should you practise ashtanga?

The traditional expectation is six mornings a week with one rest day, plus rest on the new and full moon days. That is a real commitment and it is the main reason people leave the system. If you cannot give it four mornings a week, the fixed sequence will not become familiar enough to be worth the risk it carries, and you would be better served by a slower held practice two or three times a week.
