It's not just taught in Advaita schools. It's also taught in Dvaita and Vishisht-Advaita Vedanta schools. I know because I belong to the Dvaita school of thought. Also, there is a big misconception that majority of Hindus are Advaitis. It's not so. Almost half of Hindus are Vaishnavas who either belong to Dvaita, Vishishtadvaita or Dvaita-Vishistadvaita Schools (a.k.a ISKON/Chaitanya Mahaprabhu). Yoga itself however originated from Santana Dharma (or modern day Hinduism). To back up this statement, you can read this chapter of Mahabharata which talks about the birth of Ved Vyasa (the writer of the Vedas) wherein it mentions how the Sankhya, Yoga, Pancha-ratra, Vedas and Pasupati cults came into existence: http://sacred-texts.com/hin/m12/m12c049.htm http://sacred-texts.com/hin/m12/m12c049.htm I'll quote the relevant text for your convenience: "Vaisampayana continued, "I have thus narrated to thee, O monarch, the circumstances connected with the former birth of our revered preceptor, viz., Vyasa of unstained mind, as asked by thee. Listen to me once again. There are diverse kinds of cults, O royal sage, that go by diverse names such as Sankhya, Yoga, the Pancha-ratra, Vedas, and Pasupati. The promulgator of Sankhya cult is said to be the great Rishi Kapila. The primeval Hiranyagarbha, and none else, is the promulgator of the Yoga system. The Rishi Apantaratamas is said to be the preceptor of the Vedas, some call that Rishi by the name of Prachina-garbha. The cult known by the name of Pasupata was promulgated by the Lord of Uma, that master of all creatures, viz., the cheerful Siva, otherwise known by the name of Sreekantha, the son of Brahma. The illustrious Narayana is himself the promulgator of the cult, in its entirety, contained in the Pancharatra scriptures."
