There are four main types of Yoga. They are Karma Yoga, Bhakti Yoga, Jnana Yoga, and Astanga Yoga.
Astanga Yoga has eight limbs. They are Iyama (Ethical training), Niyama (Moral Training), Asanas (Postures), Pranayama (Breathing Techniques - Conquering Prana the vital force), Pratyahara (Withdrawing the mind from the senses - Mastering of the Senses), Dharana (Concentration- focusing the mind on certain centers), Dhyana (Meditation), and Samadhi (Transcending the mind - Super conscious state).
Hatha Yoga, which is part of Astanga Yoga, includes Yoga Postures (Asanas), Pranayama (Breathing Techniques - Conquering Prana the vital force), and Pratyahara (Withdrawing the Mind from Senses - Mastering of the Senses).
HATHA YOGA AND DIFFERENCE FROM OTHERS
There are so many organizations and styles of Hatha Yogas founded by modern Indian and western teachers. The differences are usually about emphasis, such as focusing on strict alignment of the body, coordination of the breath and movement, holding the postures, or the flow from one posture to another. All the styles share a common lineage back to Astanga Yoga.
Ananda Yoga, Anusara Yoga, Power Yoga, Bikram Yoga, Integral Yoga, Integral Science of Hatha and Tantric Arts (ISHTA), Iyengar Yoga, Jivamukti - style Yoga, Kali Ray Tri Yoga, Kripalu Yoga, Kundalini Yoga, Sivananda Yoga, Svaroopa Yoga, White lotus Yoga, Viniyoga.
All Yoga philosophies are the collected experience and knowledge of ancient sages from the Indian sub-continent. People in the Indian sub-continent have practiced Astanga Yoga for 6000 years. The knowledge was passed on verbally from generation to generation for thousands of years.
WHAT ARE THE BENEFITS OF YOGA?

Relieves stress, calms the mind, frees one from restless desires, increases concentration, gives lasting pleasure and inner freedom. Helps to stretch, tone, refresh, relax and soothe the nerves. Makes one look and feel years younger, controls weight and reduces depression. It disciplines the path to physical, mental and spiritual growth and gives the experience of transcending beyond body and mind.
IS YOGA GOOD FOR HEALTH, FITNESS & MIND?
There has been quite a lot of research, all over the world. As far as the general effects on mental and physical well-being are concerned, it is now agreed that Yoga can be both pleasurable and beneficial. Western science has been studying Yoga for nearly 50 years and the evidence shows that Yoga may be helpful for specific conditions such as asthma, epilepsy, stress, cardiac risk factors, arthritis, reducing drug use and criminal activity and others. A Harvard study showed, Yoga could give the same treatment effect as a psychotherapy program. Researchers at the University of Pennsylvania School of Medicine now report that Yoga exercises can be highly effective in alleviating Carpal Tunnel Syndrome (CTS). Doctors generally now agree that relaxation, breathing techniques and meditation are the effective way of reducing stress and stress related illnesses.
Yoga postures are usually called Asanas, which are included as the third limb in Astanga Yoga. In most Indian languages, the word literally means "seats". These postures aim to improve one's physical and mental flexibility and firmness, to calm, purify and energize the body and mind and to destroy disease and death. These efforts help to direct the mind towards one pointed-ness without distractions or interruption, and to calm and steady the wandering mind in the next stage limbs of Astanga Yoga. One of the most ancient of all Yoga scripts "Tirumantiram" says "Asanas constitute one hundred and twenty six and more, eight among them are rated most high. They are Swastikasana, Padmasana, Bhadrasana, Simhasana, Gomukhasana, Sirasana, Veerasana and Sukhasana". All these main eight Asanas are in sitting Postures, which are ideal for the meditation processes. Interestingly, Tirumantiram says Swastikasana is the best among the eight.
There is no age limit for Yoga practice. People taking up yogic practice in their eighties have had very positive results in terms of improved health and mental equanimity. Even bedridden individuals with chronic diseases can still benefit from Yoga, though the practices must be carefully tailored to their particular needs. Yoga can benefit kids just as much as it helps adults. You can do Yoga even if your body is very stiff. If your body is out of shape, you should practice gently at first taking care not to create any injuries. Yoga is a great way to keep fit during pregnancy too.
Please be sure to inform your Yoga teacher of any serious health problems such as neck or back injuries, heart disease, high blood pressure, recent surgery etc. In any extreme case, you should consult a physician before joining the Yoga class. If your doctor is not familiar with Yoga, show her or him pictures of the postures or ask them to contact your Yoga teacher. It is always advised that you inform your family doctor of your physical activities, just to be on the safe side. Even though Yoga is a root of Eastern medicines such as Siddha and Ayurvedic, remember your Yoga teacher is not a doctor.
Back in the old days, it was commonly told that women must refrain from practice during the four or so days of menstruation. Now in the modern era, it is a matter of personal preference. Some women do not want to do Yoga while they have their period, many do not mind and continue to practice during menses. Listen to your body, you are the best judge of what you can and cannot do during menstruation or pregnancy. In any case, do not stand on your head (Sirasasana) during the menstrual period. All the Postures can be practiced during the first three months of pregnancy. Some postures however are inappropriate during pregnancy and menstruation. All the postures should be modified lightly according to the students' physical nature.
The number of classes you should take per week depends on your body and schedule. If you can do Yoga everyday, that is great. If not, try to do Yoga a few days a week. Certainly one class per week is not enough.
The time between two hours before and after "sun rise" or "sun set" are the best times to practice Yoga. Traditionally the Postures are practiced before the breathing techniques (Pranayama) and meditation process (Pratyahara). It does not matter in what order you are practicing the Yoga postures, but make sure you cover the counter posture for each Posture. Relaxation should and must be practiced at end of the Yoga postures.
Vegetarian food is much healthier than animal products. Besides that, a true Raja-Yogi practicing Astanga Yoga shows love and compassion for all lives. The first limb of Astanga Yoga, the Iyama insists on non-killing. Tirumular in his Tirumantiram condemns the meat-eating. However you do not have to be a vegetarian when you practice Hatha Yoga types which contain third, fourth, and fifth limbs of Astanga Yoga. Vegetarianism does not lead you to be a Yogi; Yoga leads you to non-violence. You will soon find that your desire for eating meat grows weaker.
Yoga focuses first on the health of the spine. The spinal column houses the centre of the nervous system, which plays an important part in the working of the human machine. The most important work of the Yoga postures are in strengthening and purifying the nervous system, particularly the spinal cord and nerve ganglia. The cells of the nervous system are toned and their pathways polished so that their activity is enhanced. Every cell of every organ and muscle is invigorated and supplied with fresh blood while being drained efficiently of waste products. There is much less possibility of toxic build–up, either on the cellular level or in the organs themselves. By promoting the health of the organs, including the glands of the immune system, the body’s ability to resist disease is enhanced.
