There are many different styles of yoga being taught and practiced today. Although all of the styles are based on the same physical postures (called poses), each has a particular emphasis. Here is a quick guide to the most popular types of yoga that can help you decode the schedule at your gym and figure out which class is right for you.

HATHA

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 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 that's 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 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.

BIKRAM/HOT YOGA

Pioneered by Bikram Choudhury, this style is more generally referred to as Hot Yoga. It is practiced in a 95 to 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 make use of this series.

* Note from Courtney: REMEMBER you only use the name Bikram, Anusaura, Ashtanga, Iyengar, and other styles of yoga if you are trained and certified under those teachers and in those schools, many are copyrighted. Often Hatha Yoga is used as a general term but often denotes a slower paced class. Vinyasa style is not copyrighted and often denotes a faster paced class.
