Yoga: The Complete Guide to Styles, Breathing, Benefits and Getting Started

Yoga is a mind-body practice from ancient India that combines physical postures (asanas), breathing techniques (pranayama), relaxation and meditation. The word comes from the Sanskrit root yuj, “to join”. Research suggests regular practice can modestly ease back pain, stress and low mood, and improve flexibility, balance and strength.

How we wrote this guide
Every health claim below links to the original study, its DOI or an official page, and we lean on systematic reviews and Cochrane reviews rather than single small trials. We say plainly how strong the evidence is for each benefit, and where yoga has been oversold. We checked every video, podcast, book, app, directory and account link in October 2026.

⚠️ Before you start: who should be careful

• Yoga is not a replacement for medical or mental health treatment. If you have a health condition, are pregnant or take regular medication, talk to your doctor before you start and keep taking any medicines unless they advise otherwise. Our safety section lists who should take extra care.
• If you are in crisis, contact a crisis line now. USA: call or text 988 (988 Lifeline). Canada: call or text 9-8-8 (988.ca). UK and Ireland: Samaritans on 116 123 (Samaritans). Australia: Lifeline on 13 11 14 (Lifeline). India: Tele-MANAS on 14416 (Tele-MANAS). Elsewhere: find a free local line at findahelpline.com. In an emergency, call your local emergency number (for example 911, 999, 112 or 000).

Quick answer: what is yoga and is it worth doing?

• Yoga is more than stretching. Classical yoga is a whole system for training the mind, set out in Patanjali’s Yoga Sutras as eight “limbs”. Most modern classes focus on postures and breathing, with relaxation at the end.
• The best evidence is for chronic low back pain. A 2022 Cochrane review found yoga gives small improvements in pain and function compared with no exercise, and works about as well as other exercise (Wieland et al., 2022).
• It can help mood and stress, with small-to-moderate effects on depression and anxiety symptoms in meta-analyses, best used alongside, not instead of, standard care (Cramer et al., 2018; Brinsley et al., 2021).
• It is about as safe as other exercise in clinical trials (Cramer et al., 2015), but headstands, extreme bends, forceful breathing and hot rooms carry real risks for some people.
• The style matters less than the fit. For most beginners, a gentle hatha or beginners’ class with a qualified teacher, two or three times a week, is the best place to start.

What Is Yoga?

Yoga is a family of practices that began in ancient India and aim to steady the body, the breath and the mind. In a typical modern class you move through a series of postures, pay close attention to your breathing, and finish lying still in a guided relaxation. Some classes add chanting, meditation or philosophy; others feel more like a fitness session.

The word yoga comes from the Sanskrit root yuj, meaning “to yoke” or “to join”. It is often explained as the union of body, breath and mind. In the classical texts, though, yoga is above all a discipline of attention. The second verse of Patanjali’s Yoga Sutras defines it as yogaś citta-vṛtti-nirodhaḥ: yoga is the stilling of the movements of the mind.

That gap between the original aim and today’s studio classes matters. Posture practice is the part of yoga most people meet first, but in the older traditions it was only one step on a longer path. Modern posture-based yoga is a relatively recent blend of older hatha yoga techniques with 19th- and 20th-century physical culture, as historian Mark Singleton showed in Yoga Body (2010).

Yoga is now practised worldwide. In 2016 UNESCO added yoga to its Representative List of the Intangible Cultural Heritage of Humanity, and since 2015 the United Nations has marked International Day of Yoga every 21 June. A nationally representative US survey found that 13.2% of adults had tried yoga, and back pain was the most common specific health reason for practising it (Cramer et al., 2016).

A Short History of Yoga

Yoga’s history is long and often romanticised. Here is what scholars can say with reasonable confidence.

• Early roots (before 500 BCE). Ideas of disciplined breathing, austerity and meditation appear in the Vedic literature. Claims that a seated figure on an Indus Valley seal shows a yogi are popular, but they are disputed.
• The Upanishads and the Bhagavad Gita (roughly 500 BCE–200 CE). The Katha Upanishad describes yoga as the steady control of the senses. The Bhagavad Gita describes several paths of yoga: action without attachment (karma yoga), devotion (bhakti yoga) and knowledge (jnana yoga).
• Patanjali’s Yoga Sutras (around the early centuries CE). A compact text of about 195 short verses that sets out the eight limbs of yoga. Scholars disagree about its exact date, and many place it around the 4th or 5th century CE. It says very little about postures.
• Hatha yoga (about 11th–17th centuries). Texts such as the Hatha Yoga Pradipika (15th century) describe postures, breath control, cleansing practices and energy locks, mainly as preparation for meditation.
• Modern yoga (from the late 19th century). Swami Vivekananda introduced yoga philosophy to Western audiences at the 1893 Parliament of the World’s Religions in Chicago. In the 1930s, at the Mysore Palace, T. Krishnamacharya developed flowing posture sequences and trained the teachers who shaped global yoga: B.K.S. Iyengar, K. Pattabhi Jois, his son T.K.V. Desikachar and Indra Devi.
• The global boom (from the 1960s). Iyengar’s Light on Yoga (1966) became the standard posture manual. Yoga spread through studios, gyms and, more recently, YouTube and apps.

Why history matters for you

Knowing that modern posture practice is a fairly recent development frees you from the idea that there is one “authentic” way to do yoga. Claims that a sequence is thousands of years old, or that one style is the only true yoga, are usually marketing rather than history.

Patanjali’s Eight Limbs of Yoga

The Yoga Sutras describe ashtanga yoga, the “eight-limbed” path (not to be confused with the modern Ashtanga Vinyasa style). The limbs build on each other, from how you treat others to deep meditative absorption.

1. Yama: ethical restraints. Non-harming (ahimsa), truthfulness (satya), not stealing (asteya), moderation or celibacy (brahmacharya) and non-possessiveness (aparigraha).
2. Niyama: personal observances. Cleanliness (saucha), contentment (santosha), disciplined effort (tapas), self-study (svadhyaya) and surrender to a higher principle (ishvara pranidhana).
3. Asana: posture. In the Sutras, asana mainly means a seated position for meditation that is “steady and comfortable” (sthira sukham asanam, verse 2.46). Today it means the whole repertoire of yoga poses.
4. Pranayama: breath regulation. Lengthening and controlling the breath.
5. Pratyahara: withdrawal of the senses. Turning attention inward, away from outside distractions.
6. Dharana: concentration. Holding attention on a single point, such as the breath or a sound.
7. Dhyana: meditation. An unbroken flow of attention.
8. Samadhi: absorption. A state in which the sense of a separate self falls away.

You don’t need to adopt any belief system to benefit from yoga. But the eight limbs are a useful reminder that posture practice was meant to support a calmer, kinder and more focused life, not just a more flexible body.

The Main Styles of Yoga

Almost every posture-based class in the West is, broadly, a form of hatha yoga. The styles below differ mainly in pace, how long poses are held, the use of props, heat, and how much breathing, chanting and meditation they include.

• Hatha. In the UK, a class called “hatha” usually means a moderate, all-round session of postures, breathing and relaxation. It is the best general starting point for most beginners.
• Vinyasa (flow). Postures flow one into the next in time with the breath. Classes can be gentle or very athletic, and “power yoga” is a fitness-focused form of vinyasa.
• Ashtanga (Ashtanga Vinyasa). Developed by K. Pattabhi Jois in Mysore. Students learn fixed sequences, starting with the Primary Series, using a steady ujjayi breath. Physically demanding and traditionally practised six days a week, either in a led class or “Mysore style”, where students work at their own pace with a teacher’s help.
• Iyengar. Developed by B.K.S. Iyengar. Precise alignment, longer holds and heavy use of props such as blocks, belts, chairs and bolsters, so poses can be adapted for almost any body. Teachers undergo long training. A good choice if you have injuries or stiff joints, with medical clearance.
• Yin. Slow, floor-based practice with poses held for about three to five minutes, mainly for the hips, spine and legs. Popularised by Paul Grilley and Sarah Powers. Calming, but the claim that it specifically targets “fascia” is not well tested.
• Restorative. Fully supported poses held for five to twenty minutes using bolsters, blankets and blocks, aimed at deep rest. Developed largely by Judith Lasater from her Iyengar training. It feels deeply relaxing, but in one trial it was only slightly better than a stretching programme at improving blood sugar (Kanaya et al., 2014).
• Kundalini. Combines repeated movements, dynamic breathing such as “breath of fire”, chanting and meditation in set sequences called kriyas. Brought to the West by Yogi Bhajan in 1968. A 2020 investigation commissioned by the organisation that oversees his legacy concluded that allegations of sexual misconduct and abuse against him were more likely than not true, and many teachers have since reshaped how they teach it.
• Bikram and hot yoga. Bikram yoga is a fixed series of 26 postures and two breathing exercises in a 90-minute class, in a room heated to about 40°C at 40% humidity (Hewett et al., 2015). Its founder, Bikram Choudhury, has faced multiple sexual assault allegations. Many studios now teach the same sequence as “hot 26” or “26+2”, and “hot yoga” also covers heated vinyasa classes.

Other approaches you may see include Viniyoga (breath-centred and individually adapted, from Krishnamacharya and Desikachar), Sivananda (a set class of 12 basic postures plus chanting), chair yoga, pregnancy yoga, yoga nidra (a guided lying-down relaxation) and yoga therapy.

Pranayama: Yogic Breathing

Pranayama means regulating the breath. Many people find it the most immediately useful part of yoga, because a few minutes of slow breathing can change how you feel.

What the research suggests: slow breathing at around six breaths a minute shifts the nervous system towards a calmer state, raises heart rate variability, and is linked to feeling more relaxed and less anxious (Zaccaro et al., 2018). A systematic review of pranayama trials found benefits for breathing, heart rate and blood pressure, mainly in people with asthma, though the trials were small (Jayawardena et al., 2020). In a randomised study, five minutes a day of breathing with long exhales improved mood more than the same time spent on mindfulness meditation (Balban et al., 2023).

Common techniques, from gentlest to most forceful:

Stop any breathing practice if you feel dizzy, tingly or anxious, and go back to normal breathing. Forceful breathing was among the yoga practices most often linked to reported harms (Cramer et al., 2013). The NHS has a simple breathing exercise for stress that is a good place to start.

A 20-Minute Beginner Yoga Routine

This short sequence uses gentle, widely taught postures. Do it on a non-slip mat, on an empty stomach or at least two hours after a big meal. Move slowly, breathe through your nose, and never push into pain. A stretch should feel like mild tension, not a sharp or pinching feeling. If you have a health condition, are pregnant or have had recent surgery, check with your doctor first.

1. Settle and breathe (2 minutes). Sit comfortably cross-legged or on a chair. Close your eyes and breathe slowly through your nose, letting the exhale become a little longer than the inhale.
2. Cat–cow (1 minute). On hands and knees, breathe in as you let the belly drop and lift your gaze, then breathe out as you round your back and tuck your chin. Repeat slowly 8–10 times to warm up the spine.
3. Child’s pose (1 minute). From hands and knees, sit your hips back towards your heels and rest your forehead on the mat or a cushion, arms forward or by your sides. Breathe into your back.
4. Downward-facing dog (1 minute). From hands and knees, tuck your toes and lift your hips up and back into an upside-down V. Keep your knees bent as much as you need so your back stays long. Pedal your feet gently.
5. Low lunge (1 minute each side). Step one foot forward between your hands and lower the back knee to the mat (pad it if needed). Lift your chest and sink your hips forward gently to stretch the front of the back hip.
6. Mountain pose (1 minute). Stand with feet hip-width apart, weight even, arms by your sides. Lengthen up through the crown of your head and take five slow breaths.
7. Warrior II (1 minute each side). Step your feet wide, turn your front foot out and bend the front knee over the ankle. Stretch your arms out at shoulder height and look over the front hand.
8. Tree pose (1 minute each side). Stand on one leg and place the other foot on your ankle, calf or inner thigh (never on the knee). Use a wall for balance if you need it.
9. Bridge pose (1 minute). Lie on your back with knees bent and feet flat. Press into your feet to lift your hips, hold for a few breaths, then lower slowly. Repeat three times.
10. Lying twist and relaxation (6 minutes). Hug your knees in, then let them fall to one side for a minute and the other side for a minute. Finish lying flat in savasana (corpse pose) for at least four minutes, letting your whole body go heavy.

Tip: how often, and for how long?

Many trials that showed benefits used one to three sessions a week for 8–12 weeks, and more frequent practice was linked to bigger improvements in depressive symptoms (Brinsley et al., 2021). A short daily practice you actually do beats a long weekly one you skip. For general health, the UK Chief Medical Officers’ guidelines also recommend muscle-strengthening and balance activities, and yoga counts towards both.

The Benefits of Yoga: What the Evidence Says

Yoga is one of the most-studied mind-body practices, with hundreds of randomised trials. But many trials are small, short and impossible to blind (people know they are doing yoga), so the certainty of the evidence is usually low to moderate. Here is a condition-by-condition summary.

Chronic Low Back Pain

This is yoga’s strongest evidence base. A 2022 Cochrane review of 21 trials (2,223 people) found that, compared with no exercise, yoga leads to small improvements in pain and back-related function at three months, but these were smaller than the threshold usually considered clinically important. Yoga was probably no better or worse than other exercise (Wieland et al., 2022). A wider meta-analysis of 27 studies found benefits that lasted into the longer term (Anheyer et al., 2022).

Two large trials stand out. In the UK, a 12-week programme improved back function more than usual care at 3, 6 and 12 months (Tilbrook et al., 2011). In the US, yoga was as effective as physiotherapy for function and pain in a mainly low-income population (Saper et al., 2017), and a 12-week yoga class worked about as well as a stretching class of the same length, with both doing better than a self-care book (Sherman et al., 2011). Earlier trials and reviews, including one of Iyengar yoga, pointed the same way (Williams et al., 2009; Cramer et al., 2013). NICE guidance for low back pain recommends considering a group exercise programme that can include “mind–body” approaches such as yoga (NICE NG59).

Neck Pain and Osteoarthritis

A meta-analysis of three trials found short-term improvements in chronic neck pain, disability and mood (Cramer et al., 2017). For knee osteoarthritis, yoga may improve pain, function and stiffness, but the evidence is of very low quality (Lauche et al., 2019).

Anxiety and Stress

A meta-analysis of eight trials found small short-term reductions in anxiety compared with no treatment. Effects were clearest in people with raised anxiety levels, and were not shown in people formally diagnosed with anxiety disorders (Cramer et al., 2018). In a large trial for generalised anxiety disorder, Kundalini yoga helped more than stress education, but it was not as effective as CBT, which remains the first-line treatment (Simon et al., 2021). Across 42 studies, practices that include postures were linked to lower cortisol, resting heart rate and blood pressure (Pascoe et al., 2017).

Depression and Mental Health

Yoga reduced depressive symptoms compared with usual care in an earlier meta-analysis (Cramer et al., 2013). A later meta-analysis of people with mental health conditions, including depression, anxiety, PTSD and schizophrenia, found a moderate reduction in depressive symptoms, with bigger effects when people practised more often (Brinsley et al., 2021). For PTSD, the evidence supports only a weak recommendation for yoga as an add-on (Cramer et al., 2018). If you are depressed, yoga can be a helpful extra, but talk to your GP about proven treatments too.

Sleep

In women with sleep problems, yoga improved self-reported sleep quality, though it did not clearly reduce insomnia severity or help in all groups (Wang et al., 2020). Gentle and restorative practices, and yoga nidra, are the most commonly used for sleep.

Heart Health and Blood Pressure

A Cochrane review found that yoga lowered diastolic blood pressure and improved some blood fats, but the trials were small and low quality, so the results are “exploratory” (Hartley et al., 2014). Other meta-analyses report improvements in blood pressure, cholesterol and weight (Cramer et al., 2014; Chu et al., 2016), and possible benefits for high blood pressure, though the evidence is of very low quality (Cramer et al., 2014).

Balance, Strength and Healthy Ageing

In people aged 60 and over, yoga gave small improvements in balance and medium improvements in mobility (Youkhana et al., 2016). Exercise that challenges balance reduces falls in older people (Sherrington et al., 2019), but whether yoga on its own prevents falls has not yet been shown.

Cancer, Asthma and Thinking Skills

• Breast cancer: a Cochrane review found moderate-quality evidence that yoga improves quality of life and reduces fatigue and sleep problems in the short term (Cramer et al., 2017).
• Asthma: yoga probably gives small improvements in quality of life and symptoms, but no clear change in lung function (Yang et al., 2016).
• Thinking skills: a meta-analysis found moderate improvements in attention, processing speed and executive function, from small, varied studies (Gothe & McAuley, 2015).

Why Might Yoga Work?

Researchers think yoga works through several overlapping routes: it is gentle strength and mobility exercise; slow breathing calms the stress response; focused attention resembles meditation; and it may improve how well people notice and regulate their bodily and emotional states (Gard et al., 2014). It is hard to tease apart which ingredient matters most.

Is Yoga Safe? Risks and Who Should Take Care

For most people, yes. A meta-analysis of 94 randomised trials with over 8,000 participants found that yoga caused no more adverse events than usual care or other exercise (Cramer et al., 2015). Most problems are minor muscle and joint pain, especially when people push too hard. In one UK trial, 12 of 156 people offered yoga reported adverse events, mostly increased back pain (Tilbrook et al., 2011).

Serious harms are rare but real. A review of published case reports found that headstands, shoulder stands, the lotus position and forceful breathing were the practices most often involved, and that people with glaucoma or weak bones were overrepresented (Cramer et al., 2013). US emergency department data show yoga injury rates rising, and highest in people aged 65 and over (Swain & McGwin, 2016).

Take extra care, and get advice first, if you have:

• Glaucoma or high eye pressure: head-down poses such as downward dog and standing forward bends raise eye pressure quickly (Jasien et al., 2015). Avoid inversions and ask your eye specialist. See advice on glaucoma from the US National Eye Institute or the NHS.
• Osteoporosis or osteopenia: deep forward bends and loaded spinal flexion have been linked to spinal fractures (Sinaki, 2013). Choose a teacher experienced with bone health. See advice on osteoporosis from the US NIAMS or the NHS.
• High or low blood pressure, or heart disease: avoid forceful breathing, breath-holding, long inversions and hot yoga unless your doctor agrees.
• Pregnancy: gentle and antenatal yoga are generally considered safe, and one study found 26 common postures well tolerated in healthy pregnancy (Polis et al., 2015). Avoid hot yoga (ACOG), deep twists, forceful breathing and, in later pregnancy, lying flat on your back for more than a few minutes (NHS). Tell your teacher and midwife.
• Hypermobility, recent injury or surgery, or joint replacements: avoid pushing to the end of your range and choose a slower, alignment-focused class.
• Epilepsy, a history of panic attacks or serious mental illness: be cautious with forceful breathing and long, intense meditation.

Hot Yoga Safety

Exercising at around 40°C raises your core temperature and heart rate. Drink water before and after, leave the room if you feel dizzy, sick or confused, and avoid hot yoga in pregnancy or if you have heart disease or are sensitive to heat. Research on Bikram yoga’s health effects is still limited (Hewett et al., 2015).

Teachers, Touch and Power

Physical adjustments can injure people when they are forceful, and some well-known yoga lineages have histories of abuse by their leaders. A good teacher asks before touching you, accepts “no” without fuss, and never pressures you into a pose, payment or belief.

How to Choose a Yoga Class and Teacher

Start with your goal. If you want to relax or have health problems, try a gentle hatha, Iyengar or restorative class. If you want a workout, try vinyasa or Ashtanga once you have the basics. If you want to work on breathing and meditation, look for a class that includes pranayama and relaxation.

Check the teacher’s training. Yoga teaching is not regulated by law in the UK, and teacher registers are voluntary in most places, so check credentials yourself:

• British Wheel of Yoga (BWY) is the Sport England-recognised governing body for yoga in England and Wales. Its teachers train to at least 300 hours. Search its Yoga Search directory for classes in person and online.
• Yoga Alliance is the largest international register. “RYT 200” means a teacher completed a 200-hour training at a Registered Yoga School, and “E-RYT” means experienced. You can also find a registered yoga school. Registration is voluntary.
• Yoga Australia is the national professional association in Australia and offers voluntary registered-teacher membership.
• Yoga Pros, formerly Yoga Alliance Professionals, and the Independent Yoga Network are UK registers of teachers and schools.
• Iyengar Yoga UK lists certified Iyengar teachers, who complete several years of training.
• The Complementary and Natural Healthcare Council (CNHC) is a government-approved register that includes yoga therapists, if you want yoga for a specific health condition.

Questions to ask before you book:

1. What training and insurance do you have, and how long have you been teaching?
2. Is this class suitable for a complete beginner?
3. How many people are in the class? (Smaller is better when you’re starting.)
4. Do you offer alternatives for people with injuries or health conditions?
5. Do you use hands-on adjustments, and will you ask first?

Red flags: a teacher who pushes you through pain, makes medical claims (such as yoga “curing” disease), discourages you from medical treatment, or expects devotion to a guru.

Yoga for Specific Needs

• Complete beginners: a beginners’ course of four to six weeks teaches the basic poses safely. At home, follow a structured beginners’ series.
• Older adults and limited mobility: chair yoga lets you get the benefits without getting down to the floor. BWY has trained teachers specialising in it.
• Back pain: gentle, therapeutically focused classes, such as the UK Yoga for Healthy Lower Backs programme tested in the Tilbrook trial, or Iyengar and Viniyoga.
• Stress and anxiety: restorative, yin, yoga nidra and breath-focused classes. Combine yoga with proven treatments such as CBT if anxiety is affecting your life.
• Sleep: an evening practice of gentle stretches, an extended-exhale breath and yoga nidra.
• Pregnancy and after birth: specialist pregnancy yoga with a qualified antenatal teacher, then postnatal classes once your midwife or doctor gives the go-ahead.
• Athletes and runners: yoga can complement training with mobility and balance work. Yin or gentle hatha suits recovery days.
• Desk workers: short breaks with neck, shoulder and hip stretches and a few slow breaths.
• Larger bodies: body-positive teachers such as Jessamyn Stanley, and props-heavy styles like Iyengar, make poses accessible.

Frequently Asked Questions About Yoga

What is yoga in simple terms?

Yoga is a practice from ancient India that combines body postures, breathing exercises, relaxation and meditation. The aim is to steady the body and calm the mind. Most modern classes focus on postures and breathing, finishing with a guided relaxation.

What are the main types of yoga?

The most common are hatha (an all-round, moderate class), vinyasa (flowing), Ashtanga (a fixed, vigorous sequence), Iyengar (precise alignment with props), yin (long, passive holds), restorative (fully supported rest), Kundalini (breath, movement and chanting) and hot or Bikram yoga (practised in a heated room).

Which type of yoga is best for beginners?

A gentle hatha or a dedicated beginners’ class is best for most people. Iyengar suits people with stiffness or injuries because of the props and careful instruction. Avoid starting with hot yoga, Ashtanga or fast power yoga unless you are already fit.

How often should I do yoga to see benefits?

Studies that found benefits usually used one to three sessions a week for 8–12 weeks. More frequent practice has been linked to bigger improvements in mood. Even 10–20 minutes a day at home is worthwhile.

Does yoga help with back pain?

Yes, modestly. A 2022 Cochrane review found small improvements in pain and function compared with no exercise, and similar results to other exercise. NICE guidance in the UK supports group exercise programmes, which can include yoga, for low back pain, and the American College of Physicians lists yoga among its initial non-drug options for chronic low back pain (Qaseem et al., 2017).

Can yoga help with anxiety and depression?

It can help as an add-on. Meta-analyses show small-to-moderate reductions in anxiety and depressive symptoms. For diagnosed anxiety disorders, CBT works better, and anyone with depression should also speak to their doctor.

Is yoga a good workout?

It depends on the style. Vinyasa, Ashtanga and power yoga build strength and raise your heart rate. Gentler styles build flexibility, balance and some strength but are less aerobic. Yoga counts towards the UK Chief Medical Officers’ guidance on muscle-strengthening and balance activity.

Is yoga safe?

For most people, it is about as safe as other forms of exercise. Most injuries are minor strains from overdoing it. Take extra care, and get advice first, if you have glaucoma, osteoporosis, heart disease, high blood pressure, are pregnant or have a recent injury.

Can I do yoga if I’m not flexible?

Yes. Flexibility is a result of yoga, not a requirement. Bend your knees, use blocks and straps, and choose a beginners’ or Iyengar class where poses are adapted to your body.

What is the difference between yoga and Pilates?

Both are low-impact and build strength and flexibility. Yoga comes from Indian philosophy and includes breathing practices, relaxation and meditation. Pilates was developed by Joseph Pilates in the 20th century and focuses more on core strength and controlled movement.

Is yoga religious?

Yoga grew out of Indian spiritual traditions, especially Hindu, Buddhist and Jain thought, and some classes include chanting or philosophy. But most modern classes are not religious, and you can practise without adopting any beliefs.

What do I need to start yoga?

Comfortable clothes you can move in and a non-slip mat. Blocks, a strap and a cushion are useful but optional; household items such as books and a belt work too. For a class, arrive a few minutes early and tell the teacher about any injuries.

Key Takeaways

• Yoga combines postures, breathing, relaxation and meditation, with roots in ancient India and Patanjali’s eight limbs.
• Modern posture-based yoga is relatively recent, shaped largely by Krishnamacharya and his students in the 20th century.
• Styles differ in pace, heat and props. Gentle hatha or a beginners’ course is the best start for most people.
• The strongest evidence is for chronic low back pain, with moderate evidence for mood, stress, balance and quality of life in breast cancer.
• Effects are usually small to moderate, and yoga works best alongside, not instead of, proven medical care.
• Slow breathing (pranayama) is a quick, practical way to calm down. Be careful with forceful techniques.
• Yoga is about as safe as other exercise, but avoid inversions with glaucoma, deep spinal flexion with osteoporosis, and hot yoga in pregnancy.
• Choose a properly trained teacher through a register such as Yoga Alliance (international), Yoga Australia, the British Wheel of Yoga or Iyengar Yoga UK.
