Iyengar yoga emphasizes holding poses for a longer period of time in order to obtain maximum benefit. This builds strength and increases flexibility. Iyengar yoga is suitable for people of all types - from the athletic to those that are not yet physically fit. This includes those who are overweight, elderly or ill.
One unique aspect of Iyengar yoga is the use of props such as yoga blankets, blocks, straps and bolsters. These props are used to help the student attain ideal alignment and can be used according to the student's own needs.
