What Is Yoga? A Beginner's Guide to Styles, Benefits and How to Start

Yoga is a practice from India that trains the body, the breath and the attention together. The word comes from the Sanskrit root yuj, "to yoke" or "to join". In a modern class that means poses (asana), breathing exercises (pranayama) and a few minutes of rest or meditation. In the older tradition, the poses were a small part of a larger system for steadying the mind.

What yoga means, in plain words

Ask ten teachers what yoga is and you get ten answers. They are less different than they sound. Most describe the same thing from different sides: you pay close attention to what your body and breath are doing, and you keep that attention for a while.

The oldest short definition comes from the Yoga Sutras of Patanjali, usually dated to the first centuries CE. Its second verse calls yoga the stilling of the movements of the mind. The poses you do in class came much later as a practice in their own right. If you want the Sanskrit in detail, our guide to what the word yoga means and how the classic texts define it goes through the roots and the definitions one by one.

The eight limbs: yoga is more than poses

Patanjali describes yoga as a path with eight parts, the ashtanga or eight limbs:

1. Yama: how you treat others, starting with non-harming.
2. Niyama: how you treat yourself, such as cleanliness and study.
3. Asana: posture. In the Sutras, a seat that is steady and comfortable.
4. Pranayama: work with the breath.
5. Pratyahara: drawing the senses inward.
6. Dharana: concentration on one point.
7. Dhyana: meditation, attention that stays.
8. Samadhi: complete absorption.

Only one of the eight is posture. Our article on the 8 limbs of yoga explains each one, and you do not need to study them before your first class. Most people start with the body and find the rest later, or never, and both are fine.

What happens in a yoga class

A typical class lasts 20 to 75 minutes and has a shape you will soon recognise:

• Arriving. A few minutes seated or lying down, noticing the breath.
• Warming up. Gentle movement of the spine, often a round of Sun Salutations.
• Standing poses. Lunges, warriors, balances. This is where you work hardest.
• Floor poses. Forward folds, twists, hip openers, gentle backbends.
• Rest. Five to ten minutes in Savasana (Corpse Pose), lying still on your back.

The teacher links each movement to the breath: lift the arms as you breathe in, fold as you breathe out. That link is what separates yoga from a stretching session. You will hear Sanskrit names for the poses. Our list of 50 Sanskrit yoga terms covers the ones that come up most.

The main styles of yoga

Almost every style you see on a studio timetable is a form of hatha yoga, the physical branch of the tradition. They differ in pace, in how long you hold a pose and in how much the sequence changes from class to class.

• Hatha yoga: poses held for several breaths, with time to set up and come out. A good place to start. Hatha means "force" or "effort" in Sanskrit.
• Vinyasa flow: poses linked into a continuous flow, one movement per breath. More sweat, more variety.
• Ashtanga yoga: a fixed series of poses in the same order every time, taught by Sri K. Pattabhi Jois in Mysore. Demanding, and you can measure your progress against the same sequence.
• Yin yoga: floor poses held for three to five minutes with the muscles as relaxed as you can make them. Slow and quiet, and harder than it looks.
• Restorative yoga: a few poses fully supported by bolsters and blankets. The goal is rest.

Many of these styles trace back to one teacher, T. Krishnamacharya, who taught in Mysore in the 1930s. You can read how they branched off in the yoga styles of the Krishnamacharya lineage. Newer offshoots go further from that root, and we cover them in our guide to acro, goat and laughter yoga.

What yoga does for your body and mind

Yoga is low-impact exercise. You hold your own weight on your legs and arms, you stretch, and you balance. That alone gives you the ordinary gains of training: stronger legs, more mobile hips and shoulders, better balance if you practise standing on one leg.

The research is strongest in a few areas. Reviews of clinical trials find that yoga helps people with chronic low back pain move better and hurt a little less, about as much as other exercise does. The American College of Physicians lists it among the first non-drug options for chronic low back pain. Studies also point to modest help with stress, sleep and balance in older adults.

Some of the effect comes from the breath. A slow, long exhale shifts the nervous system toward rest, and yoga classes use slow breathing all the time. Our overview of the health benefits of yoga goes through the claims one by one.

What yoga does not do: it does not cure illness, and it does not replace treatment. Be wary of any class or book that promises it will.

Is yoga safe for beginners?

For most people, yes. Yoga has an injury rate similar to other low-impact exercise. Most injuries come from forcing a pose: pulling into a deep forward fold, or putting weight on the neck in a headstand before you are ready.

Talk to your doctor first if you are pregnant, have high blood pressure, glaucoma, osteoporosis, a recent injury or surgery. Many poses still work for you, some need a change and a few are best skipped. Our 10 tips to avoid yoga injuries are worth reading before your first week.

How to start

Equipment. A non-slip mat and clothes you can move in. A block, a strap and a folded blanket help, and at home a stack of books and a belt do the same job.

How often. Two or three sessions a week of 20 to 30 minutes will teach your body the basic poses within a month. Short and regular beats long and rare.

Which poses. Learn a handful well: Tadasana (Mountain Pose), Adho Mukha Svanasana (Downward-Facing Dog), Balasana (Child's Pose) for rest, and a warrior or two. Our essential yoga poses for beginners has the full starter set.

A teacher helps. In a studio, a teacher can see what you cannot. At home, a video class gives you the sequence and the cues, and you learn to feel the rest. Our tips for practising yoga at home cover space, timing and how to choose a class.

"I'm not flexible enough"

This is the most common reason people give for not starting. It has the order the wrong way round. Flexibility comes from practice, and nobody arrives with it. Most beginner poses need less range than you think, and every pose has a version with a block under the hands or bent knees.

Stiff people often make good students. They cannot hang in their joints, so they have to use their muscles.

Where sources disagree

Ancient or modern? You will read that yoga is 5,000 years old. The ideas behind it are old: meditation and breath control appear in texts from well over 2,000 years ago. The flowing posture classes of today are much younger. Historians such as Mark Singleton have shown that modern posture practice took shape in the early 20th century, mixing hatha yoga with Indian and European gymnastics. The Hatha Yoga Pradipika, a 15th-century manual, describes only fifteen poses in detail. Both stories are true for different parts of what we call yoga.

Exercise or spiritual practice? Some teachers say yoga without its philosophy is only stretching. Others teach it as exercise and leave belief out. The tradition itself gives no single answer: the Sutras put ethics first, while many hatha texts focus on the body. What you do on the mat can be one, the other or both.

Big claims about benefits. Studio marketing often promises more than the research shows. Studies of yoga are often small and short, and it is hard to run a blinded trial of an exercise. The honest line: good evidence for back pain and balance, reasonable evidence for stress, weak evidence for most of the rest.

If you want a structured start, the four-week Yoga for Beginners program teaches the basic postures in twenty-minute classes, one step at a time.

Frequently asked questions

What is yoga in simple words?

Yoga is a practice of moving, breathing and paying attention at the same time. In most classes you hold and move through poses in time with your breath, then rest. The word comes from Sanskrit and means "to join".

What are the benefits of doing yoga?

The best-supported benefits are less pain and better movement for people with chronic low back pain, better balance, and some help with stress and sleep. You also get the ordinary gains of exercise: strength and mobility. Yoga does not cure illness.

What are the 7 types of yoga?

Lists vary, and there is no official seven. The tradition names paths such as karma yoga (action), bhakti yoga (devotion), jnana yoga (knowledge), raja yoga (meditation) and hatha yoga (the body). On a studio timetable you will mostly find hatha, vinyasa, Ashtanga, yin, restorative, Iyengar and hot yoga.

Is it okay for Christians to do yoga?

Opinions differ. Some churches discourage it because of its Hindu roots. Many Christians practise it as exercise and breathing, without the chanting or the philosophy. A class that sticks to poses and breath asks for no belief. If chanting bothers you, you can stay quiet.

Do I need to be flexible to start yoga?

No. Flexibility is a result of practice. Every beginner pose has an easier version, with bent knees, a block under the hands or a smaller range.

How often should a beginner do yoga?

Two or three times a week, 20 to 30 minutes each time, is a good start. Regular short sessions teach the poses faster than one long class now and then.

Is yoga a religion?

No. Yoga grew up in the religious world of ancient India, and Hindu, Buddhist and Jain traditions all have forms of it. A modern class asks for no belief. You can practise it for the body alone, or take an interest in the philosophy too.

Can I learn yoga at home?

Yes. Start with slow beginner classes, go easy on anything that hurts, and learn a few basic poses well. A teacher in a studio can correct you in person, so a class now and then is a good complement.
