There are various types of Yoga that we have all probably heard of. Some of them have become "Americanized" for lack of a better term. Below breaks down the most common types you'll see in today's fitness clubs. Further, the roots of Yoga are outlined for your information.

HATHA
A gentle form a Yoga, the most common form that focuses on basic postures that flow in and out with emphasis on breathing techniques. Hatha Yoga is what most people in the West associate with the word "Yoga" and is practiced for mental and physical health.

ASHTANGA
The eight limbs connoted by the word 'Ashtanga' refer specifically to the eight spiritual practices outlined by the Yoga Sutra, the original Yoga text which is just as relevant today as when first composed. 'Ashtanga' can be composed of 6 set series, each increasing with more difficulty. It is usually combined or referred to as Ashtanga Vinyasa Yoga (see below).

VINYASA
A dynamic form of yoga that connects postures and creates a flow between traditional yoga postures. The 'Vinyasa flow' is used especially during the Sun Salutation series.

BIKRAM and HOT YOGA
Bikram Yoga is ideally practiced in a room heated to 105°F (40.5°C) with a humidity of 40%. Classes include 26 postures, guided by specific dialogue and breathing techniques.

KUNDALINI
Focuses on deep, very rhythmic breathing and prepares the body for state of meditation. Also focuses on bring energy into the body through intense visualization.

IYENGAR
Stresses the alignment of the body and perfecting poses. Participants will learn true limitations as they hold positions for long periods of time. This type of yoga also incorporates props.

RESTORATIVE
Implements the use of yoga props and supports for participants with injuries. Ideal for people wanting deep relaxation through a safe, supportive manner.

POWER YOGA
An Americanized version of Ashtanga Vinyasa that intensifies poses by moving more rapidly between one pose to the other. Poses test one's endurance and challenge the physical limitations of the muscles and core. Power Yoga can also refer to a shortened version of a Yoga class. i.e. a 45 minute class versus a 60 or 90 minute class but the benefits are seemingly the same because the pace of class is quickened.
