Vinyasa yoga: flowing with the breath, how hard it is, and how to start

Movement linked to breath

The NHS says vinyasa flow places strong emphasis on connecting the breath with the yoga poses. The British Wheel of Yoga calls it a fluid form of yoga that can be quite athletic, and power yoga a form of it.

Light to moderate exercise

The Compendium of Physical Activities rates vinyasa at 2.7 METs, which is light; a lab study measured 3.6, which is moderate. The US physical activity guidelines list active forms of yoga, such as vinyasa or power yoga, among moderate-intensity activities.

Sources 3, 4, 5

Less energy than a brisk walk

In the lab, an hour of vinyasa used about 52 kcal (kilocalories) less than a self-paced brisk walk. By our arithmetic, an hour of vinyasa uses about 190 to 250 kcal for a 70 kg person, against about 335 for brisk walking.

Sources 4, 3, 6

Few outcome trials, all small

Vinyasa helped women quit smoking in the short term in one small trial, and Ashtanga-based classes raised leg strength in another. Across 306 yoga trials, no style had better results than another.

Sources 7, 8, 9

About as safe as other exercise, with care

In trials, yoga was as safe as usual care or other exercise, but in one study about 1 in 10 studio practitioners developed pain caused by yoga over a year. Teachers warn that repetition and tiredness are when form slips.

Sources 10, 11, 12

Start slowly

Choose a beginners' or slow-flow class, step back rather than jump, lower with your knees down, and rest in child's pose whenever your breath runs ahead (our suggestions, drawing on teacher advice and on the US National Center for Complementary and Integrative Health's advice to learn with a qualified teacher).

Sources 13, 12

Flowing with the breath

The NHS describes vinyasa flow as placing "strong emphasis on connecting the breath with the yoga poses", and says its 50-minute vinyasa video suits most people in good health with a reasonable level of fitness. The British Wheel of Yoga (BWY): "Vinyasa is a fluid form of yoga, in its practice you will be moving from one posture to another, coordinating with the breath. It can be quite athletic."

Sources 1, 2

What the word means

In Ashtanga yoga, each counted movement is a vinyasa, done on one breath in or one breath out, with a set point for your gaze. Sun salutation A has 9 of them, including the low push-up (chaturanga), upward dog and 5 breaths in downward dog. An Ashtanga school calls ujjayi, breathing through a slightly narrowed throat, "the foundation of vinyasa". More loosely, vinyasa means linked, flowing movement.

Sources 14, 15

Where it comes from

In the 1930s, T. Krishnamacharya taught yoga at the palace in Mysore, India. A Wellcome Collection history describes his system as postures joined by a repeating sequence based on sun salutations, each held for a relatively short time, in contrast with the older tradition of holding one pose for a long time, with counted breaths helping groups move together.

Pattabhi Jois's Ashtanga links its set series of postures in the same way, in a counted breath sequence, and still opens with 5 rounds each of sun salutations A and B. Power yoga arose in the West in the 1990s, from practitioners of Ashtanga and other styles.

Sources 16, 17

How a class runs

Sequences vary by teacher. A measured power vinyasa class ran from an opening sequence through sun salutations, crescent lunges, balancing and standing poses and backbends to a restorative close, and in a similar lab class the last 15 minutes were the restorative part. Another 90-minute group class had a warm-up, fast sun salutations, other postures and a cool-down.

Sources 18, 4, 19

Heated classes

Some studios heat their vinyasa classes. Our hot yoga guide explains what the heat does and doesn't add.

Source 20

Light by one measure, moderate by anotherEmerging evidence

The 2024 Compendium of Physical Activities lists vinyasa at 2.7 METs, in the light range: the World Health Organization (WHO) puts light activity at 1.5 to under 3 METs and moderate at 3 to under 6. In a lab study of 38 adults, an hour of vinyasa averaged 3.6 METs, just into the moderate range, against 4.4 for brisk walking at their own pace. Both are averages over a whole class.

Sources 3, 21, 4

Harder in placesEmerging evidence

In a measured class, energy use and heart rate differed between sequences, and heart rate was lower in the opening and closing restorative sequences than in sun salutations, lunges, balances, standing poses and backbends. Fast sun salutations cost the most: 8 minutes of sun salutation B at high speed used about 19 kcal more than at standard speed.

A review of 17 studies classed yoga as typically light activity, with a few sequences, such as sun salutations, reaching moderate or vigorous. In yoga instructors, 10 minutes of vigorous sun salutations averaged 8.7 METs: short, fast bursts by experienced people can be vigorous.

Sources 18, 22, 23, 24

Heart rate overstates the effortEmerging evidence

In yoga, heart rate rises more than energy use: a review found that oxygen use usually classed yoga as light, while heart rate put different styles in several intensity bands. In the lab, walking at the same heart rate as the vinyasa class used more energy than the class.

By heart rate, people spent about 40% of an unheated community vinyasa class at moderate intensity. Because heart rate overstates yoga's effort, the true share of moderate minutes is probably lower (our reading).

Sources 25, 4, 20

Calories: our arithmetic

For a 70 kg person, an hour of vinyasa uses about 190 kcal at the Compendium's 2.7 METs, or about 250 at the 3.6 measured in the lab, including the energy you'd use sitting anyway. That compares with about 280 for power yoga (from an estimated value), about 335 for brisk walking (4.8 METs) and about 595 for running at 12 minutes a mile (8.5 METs). In the lab, an hour of vinyasa used about 52 kcal less than a self-paced brisk walk.

Sources 3, 6, 26, 4

Does it count toward the guidelines?Emerging evidence

The US physical activity guidelines list active forms of yoga, such as vinyasa or power yoga, among moderate-intensity activities. They say yoga can include time at light or at moderate intensity, and can be both aerobic and muscle-strengthening. The NHS asks for 150 minutes of moderate activity a week, where you can still talk but not sing, plus strength work on 2 days, and lists yoga among muscle-strengthening activities.

Our reading: the brisk parts of a class count toward your 150 minutes, the whole class counts as strength work, and a slow class mostly doesn't count as aerobic.

Sources 5, 27, 20

Power yoga

The BWY calls power yoga a form of vinyasa, and it arose in the West in the 1990s. It's usually faster and more vigorous. The Compendium's 4.0 METs for power yoga is an estimate, not a measurement; in 27 young adults, about 45 minutes of power yoga kept heart rates in the moderate and vigorous zones for more of the time than in the light zone, and they lost about 0.28 kg of fluid. A small pilot trial found power yoga improved slowness, stiffness and strength in 26 people with Parkinson's disease.

Sources 2, 16, 3, 28, 29

Ashtanga

Ashtanga follows the same set series every time, opening with 5 rounds each of sun salutation A (9 movements) and B (17). The BWY describes it as a physically strong form of yoga with set sequences (the primary, intermediate and four advanced series), with ujjayi breathing central to its practice. Our types of yoga guide compares Ashtanga and vinyasa.

Hot vinyasa

In community classes, heat made no significant difference to the time spent at moderate intensity by heart rate. Our hot yoga guide explains what heat does and doesn't add, and its warning signs.

Source 20

Which to try first

Start with a slow-flow or beginners' vinyasa class, and try power yoga or Ashtanga once the sun salutations feel easy (our suggestion).

How much research there is

A large research database lists about 30 papers with vinyasa, power yoga or Ashtanga in the title, mostly studies of energy use, surveys or plans for trials. There are no large trials of what vinyasa does for health.

Source 30

Quitting smokingMixed evidence

In 55 women having quit-smoking treatment, twice-weekly vinyasa classes raised quit rates at 8 weeks more than a wellness class did, but the difference wasn't significant at 6 months. The larger follow-up trial of 227 adults used Iyengar yoga, not vinyasa. Across 7 trials, yoga's effect on quitting was positive but inconsistent.

Sources 7, 31, 32

Strength, arteries and boneEmerging evidence

In 34 women aged 35 to 50, 8 months of twice-weekly Ashtanga-based classes raised leg-press strength by about 11%, while it fell by about 7% without them. Artery stiffness, blood pressure and bone density didn't change.

Sources 8, 33

Parkinson's diseaseMixed evidence

In a pilot trial of 26 people with mild to moderate Parkinson's, power yoga twice a week for 3 months reduced slowness and stiffness and improved strength and quality of life. It needs repeating in a larger trial.

Source 29

Blood pressure straight after a classEmerging evidence

In 18 healthy adults, the top (systolic) blood pressure reading was 8 millimetres of mercury lower 5 minutes after an hour of vinyasa than after sitting, but no different an hour later. In 30 practitioners, an hour's class was followed by better measures of artery function and blood fats and less negative mood, in a study without a comparison group.

Sources 34, 35

WeightEmerging evidence

Inside a 6-month diet programme, 50 adults lost about the same weight with vinyasa as with restorative hatha yoga (3.8 against 3.4 kg). Our yoga for weight loss guide covers the rest.

Source 36

Low moodEmerging evidence

Across 218 exercise trials, the effect on depression grew with the intensity prescribed, and yoga was among the better types of exercise, on very low-certainty evidence. Vinyasa itself has been tested for low mood only in small studies without a comparison group, such as one of 11 people.

Sources 37, 38

No style beats anotherEmerging evidence

Across 306 randomised yoga trials, the share with positive conclusions didn't differ between styles.

More pain with vigorous yoga, in one trialEmerging evidence

In sedentary cancer survivors, 40% reported mild to moderate pain with vigorous, vinyasa-based yoga, against 10% with restorative yoga.

Source 39

In trials, as safe as other exerciseEmerging evidence

Across 94 trials with 8,430 people that reported harms, serious and non-serious problems were no more common with yoga than with usual care or other exercise, though reporting was often poor.

Source 10

Outside trials, injuries happenEmerging evidence

Across 9 surveys, 4.6% of practitioners reported a problem linked to yoga in the past year, mostly sprains and strains, and meniscus (knee cartilage) injuries were more common than in people who don't practise. In 354 studio practitioners followed for a year, 10.7% developed pain caused by yoga, and more than a third of them lost practice time or had symptoms lasting over 3 months.

US emergency departments saw an estimated 63,280 yoga injuries from 2004 to 2023, with hip injuries a larger share at 45 and over; earlier data found the highest injury rate at 65 and over. Choose slower classes as you get older, and keep balance poses near a wall.

Sources 40, 11, 41, 42

What published cases of harm showMixed evidence

A review of 76 published cases of harm found headstand, shoulder stand, lotus and forceful breathing the practices most often involved, and a 2026 review of case reports found headstand the pose most often implicated. One case report describes compartment syndrome of the back muscles, with muscle breakdown, after a power yoga class; the person recovered fully.

Sources 43, 44, 45

Repetition and speedMixed evidence

Yoga teachers warn that repeated sun salutations, done fast or when tired, risk overuse, especially in chaturanga and warrior I. We found no study of chaturanga's load on the wrists or shoulders, so this is expert opinion.

Sources 12, 30

GlaucomaEmerging evidence

The American Academy of Ophthalmology advises breathing out gently and slowly, avoiding breath holds or a restricted out-breath (as in ujjayi), avoiding strenuous inversions, and choosing a slower style that uses props. In a lab study, downward dog raised eye pressure the most of four head-down poses. Use a chair or wall for downward dog, half-way lifts instead of full folds, and normal breathing.

Sources 46, 47

PregnancyStrong evidence

The US National Center for Complementary and Integrative Health advises avoiding hot yoga in pregnancy because it can cause overheating, and the NHS says it's not recommended to start a new vigorous activity in pregnancy. If you already practise, slow down, step rather than jump, swap face-down poses for all-fours, and see our pregnancy yoga guide.

Sources 13, 48

OsteoporosisStrong evidence

Flowing sequences fold forward many times, and the UK consensus on exercise for osteoporosis advises modifying or avoiding sustained, repeated or end-range forward bending. Use half-way lifts with a long back, and hinge from your hips.

Source 49

Wrists and shoulders

Repeated chaturanga and upward dog load the wrists and shoulders. With pain, lower on your knees, use your forearms or fists, or leave out the push-up part (our suggestion).

Your first few weeks

Our suggestions, drawing on teacher advice that repetition and tiredness are when form slips, and on the advice to learn with a qualified teacher:

• Go to a beginners', slow-flow or level 1 class, or follow our 30-minute beginners' flow.
• Learn sun salutation A step by step first: our sun salutation guide breaks it down.
• Step back rather than jumping, and lower with your knees down until a full push-up is strong.
• Use low cobra instead of upward dog, and bend your knees in downward dog.
• Rest in child's pose whenever your breath gets ragged: the breath sets the pace.
• Try unheated classes first.

Sources 13, 12

How often

Two or three classes a week of 45 to 75 minutes, with at least one other brisk activity a week, such as walking, cycling or running (our editorial starting point, from the guidelines and the measured intensities).

Sources 27, 4

Call 999

For chest pain that feels tight or like squeezing, or that spreads to your arms, neck or jaw, or chest pain with feeling sick or a racing, slow or fluttering heartbeat. In the US, call 911.

Source 50

Heat illness in a hot class

Stop for dizziness, a headache, feeling sick, heavy sweating, pale clammy skin or cramps in your arms, legs or stomach: get somewhere cool, drink and cool your skin. It should improve within 30 minutes. Call 999 if it doesn't, or for hot skin that isn't sweating, a fast heartbeat, fast breathing or breathlessness, confusion, a fit or passing out.

Source 51

Muscle breakdown after a hard class

Very sore, swollen or weak muscles with dark, red or cola-coloured pee, or peeing less than usual, after an unusually hard class need medical help the same day: call NHS 111, or go to A&E if you feel very unwell. It has happened after a power yoga class.

Check first

Get advice before starting if you have a health problem, an injury or symptoms, have had a recent heart attack or operation, are pregnant or have recently given birth, or have high blood pressure that isn't under control or heart disease. Tell your teacher about any condition.

Sources 1, 13

Stop the pose

For sharp or increasing pain, tingling, numbness, dizziness, or pain in a joint as you come out. Rest in child's pose, and get it checked if it doesn't settle.

"Vinyasa burns as many calories as running"Strong evidence

Running at 12 minutes a mile is 8.5 METs, against 2.7 for vinyasa, and measured vinyasa used less energy than brisk walking.

Sources 26, 3, 4

"Vinyasa is cardio, so I don't need anything else"Emerging evidence

By heart rate, about 40% of a typical class reached moderate intensity, and heart rate overstates yoga's effort. Count the brisk parts toward your 150 minutes, and add walking, cycling or running.

"A higher heart rate in a hot or fast class means more calories"Emerging evidence

In yoga, heart rate runs ahead of energy use, and our hot yoga guide explains that heat raises heart rate without raising energy use. Speed does add a little: fast sun salutations used about 19 kcal more in 8 minutes.
