Iyengar yoga is a form of Hatha yoga that focuses on the structural alignment of the body through asanas (physical postures) and pranayama (breathing practices). It aims to unite the body mind and spirit for health and well-being. This discipline is considered a powerful tool to relieve the stresses of modern day life. Iyengar yoga is characterized by great attention to detail and precision of alignment. This form of yoga has pioneered the use of various props such as belts, blocks, blankets chairs etc. to make the poses accessible to those who are unable to fully achieve them and to help practitioners to have greater understanding of them. Iyengar yoga is widely practiced in many countries including the USA, Australia and many European countries as well as India.
