Nowadays many different styles of yoga are offered at yoga studios and sports clubs all over the world. For instance, Hatha is a very general term that can cover many of the physical types of yoga. Normally Hatha class is slow-paced and gentle and it provides a good introduction to the basic yoga poses.
Whereas Vinyasa Flow tends to be a more vigorous style based on the performance of a series of poses called Surya Namaskara (Sun Salutations) in which movement is matched to the breath. Vinyasa means breath-synchronized movement.
Ashtanga, which means "eight limbs" in Sanskrit, is a style of yoga spread to the modern world by Sri K. Pattabhi Jois. Its characteristic is seen in Vinyasa and the way a set series of poses is performed, always in the same order. Ashtanga is physically demanding because of the constant movement from one pose to the next, a process producing intense internal heat and a profuse, purifying sweat that detoxifies muscles and organs.
Power Yoga has been evolved from Ashtanga and it has many Ashtanga characteristics. It does not, however, necessarily follow the set Ashtanga series of poses.
Another popular style is Iyengar which is based on the teachings of B.K.S Iyengar. This style of yoga is most concerned with bodily alignment. It means that your body should be positioned in the precise way in each pose in order to obtain the maximum benefits and avoid injury. Iyengar class usually emphasizes holding poses over long periods and it also encourages the use of props such as blocks and straps, in order to bring the body into alignment.
The aforementioned styles could be all described as yang style of yoga and they emphasize internal heat, and the lengthening and contracting of our muscles, while Yin Yoga targets the connective tissues, such as the ligaments, bones, and even the joints of the body that normally are not exercised very much in a yang style of asana practice.
To relieve chronic stress, Restorative Yoga is considered very beneficial. In Restorative Yoga class, mainly supine or reclining poses are performed. By supporting the body comfortably with props, the body is alternately stimulated and relaxed to move toward balance.
The above are just a few examples of yoga styles and there are many more styles widely available. One thing for sure is that regardless of age, body type, life style and personality, you can easily find a style of yoga that will best suit you.
