Yoga schools are as diverse as the meanings of the bracket term yoga. Within the major branches of yoga such as haṭha, lāya, rāja, jñāna, and bhakti there are many different schools and lineages, both extant and defunct. Since the late 19th century, a great number of distinct new styles of "Yoga" have been introduced by individual teachers. Some schools and traditions are occasionally referred to as yoga or yogic for their similar practices, despite having no foundation in the Indian tradition; these include Shin Shin Tōitsu-dō, and Daoyin.

Styles of yoga as exercise

thumb|upright=1.7|Different schools teach yoga with emphasis on [[aerobic exercise (such as Bikram Yoga), precision in the asanas (like Iyengar Yoga), or spirituality (like Sivananda Yoga).
