Based on the teachings of the yogi B.K.S Iyengar, this style of practice is most concerned with bodily alignment. In yoga, the word alignment is used to describe the precise way in which your body should be positioned in each pose in order to obtain the maximum benefits and avoid injury. Iyengar practice usually emphasizes holding poses over long periods versus moving quickly from one pose to the next (flow). Also, Iyengar practice encourages the use of props, such as yoga blankets, blocks and straps, in order to bring the body into alignment. source: yoga.about.com

The emphasis in Kundalini is on the breath in conjunction with physical movement, with the purpose of freeing energy in the lower body and allowing it to move upwards. All asana practices make use of controlling the breath. But in Kundalini, the exploration of the effects of the breath (also called prana, meaning energy) on the postures is essential. Kundalini uses rapid, repetitive movements rather than poses held for a long time, and the teacher will often lead the class in call and response chanting. source: yoga.about.com
