Of all the practices, yin yoga has one of the slowest paces and also places great emphasis on the meditative aspects of yoga. Yin involves a lot of seated postures that you hold for longer periods of time, typically 3-5 minutes. One of the main aims is to improve flexibility and circulation by putting controlled stress on your tendons, ligaments and fascia.
Like Hatha, Yin is a great entry point for those who are new to yoga. Since classes are relaxed and move at a slower pace, you can really take the time to get a stronger sense of connection with your body.
