Hatha is a very general term that can encompass many of the physical types of yoga. If a class is described as Hatha-style, it is probably going to be slow-paced and gentle, and can provide a good introduction to the basic yoga poses.

VINYASA

Like Hatha, Vinyasa is a general term that is used to describe many different types of classes.

Vinyasa, which means breath-synchronized movement, tends to be a more vigorous style based on the performance of a series of poses called Sun Salutations in which movement is matched to the breath. A Vinyasa class will typically start with a number of Sun Salutations to warm up the body for more intense stretching which is done at the end of class.

ASHTANGA & POWER YOGA

Ashtanga, which means eight limbs in Sanskrit, is a fast-paced, intense style of yoga. A set series of poses is performed, always in the same order. Ashtanga practice is very physically demanding, because of the constant movement from one pose to the next. In yoga terminology, this movement is called flow. Ashtanga is also the inspiration for what is often called Power Yoga. If a class is described as Power Yoga, it will be based on the flowing style of Ashtanga, but not necessarily keep strictly to the set Ashtanga series of poses.

IYENGAR

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 of the pose 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.

KUNDALINI

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 holding poses for a long time, and the teacher will often lead the class in call and response chanting.

BIKRAM/HOT YOGA

Pioneered by Bikram Choudhury, this style is more generally referred to as Hot Yoga. It is practiced in a 95-100 degree room, which allows for a loosening of tight muscles and profuse sweating, which is thought to be cleansing. The Bikram method is a set series of 26 poses, but not all hot classes are make use of this series.
