Flow yoga is a type of yoga that connects your movements to your breathing. In flow yoga, the yoga postures or "asanas" flow smoothly from one yoga position to the next on either an inhalation or an exhalation.

Flow Yoga is also called Vinyasa Yoga, which means "breath-synchronized movement." The thought is that the controlled breathing that accompanies the yoga positions in Flow Yoga cleanses the body and creates energy. This philosophy is the basis for other popular yoga styles like Ashtanga Yoga and Power Yoga.

But unlike the predetermined sequences of Ashtanga Yoga, there is no single set of rules or philosophy governing Flow Yoga.
Instructors have the freedom to create unique experiences by linking yoga positions according to their personalities and the needs or mood of the class. This makes Flow Yoga a great option for both beginners and experienced yogis alike.

Power yoga is an exercise-based approach to traditional yoga. Based loosely on the Ashtanga style of yoga, power yoga is a vigorous vinyasa-style practice that was designed as a means to get fitness-minded westerners interested in yoga. Power yoga sessions do not follow a specific sequence of poses, and subsequently practices can vary greatly between classes and instructors. However, every practice is based on the fundamental goal of increasing flexibility and strength through physically challenging postures.

Postures in power yoga are typically linked together by a sequence called a vinyasa, which includes downward dog and upward dog. The purpose of a vinyasa is to create heat and energy in the body and to "refresh" the muscles after the previous pose. Power yoga sessions often also focus on a style of breathing called Ujjayi breath, a strong breathing technique that forces air through the back of the throat.

Unlike most traditional yoga practices, which focus on the spiritual and meditative aspects of the poses, power yoga is more focused on the physical aspect of the session, and it is most often used as a means to get fit or lose weight rather than achieve enlightenment.

Kundalini Yoga is a spiritual and physical practice closely associated with Hatha yoga that is designed to facilitate spiritual enlightenment. More than just a means to fitness, Kundalini yoga is based on the fundamental principle of awakening the seven chakras through breathing, chanting and meditation. The Kundalini is an untapped source of energy thought to sit at the base of your spine like a coiled snake, and it's through the yoga practice that this energy is drawn up. Full enlightenment is thought to be achieved when the energy reaches the Crown Chakra. Kundalini yoga is relatively new to Western society -- it was introduced to North America in 1969 by the 3HO (Healthy, Happy, Holy Organization.)

A Kundalini yoga session involves a series (called kriya) of postures (called asanas,) each done with an emphasis on the breathing process. Sessions also involve chanted mantras and meditation. Though it's a highly spiritual form of yoga, don't expect your Kundalini yoga session to be easy -- the practice is very physically intense.

Hatha yoga is term that applies to the physical practice of yoga. There are eight different "limbs" of yoga and only one involves physical poses. So when you practice Ashtanga or Kundalini yoga, you are still practicing Hatha yoga. Hatha yoga can essentially be used interchangeably with the word yoga.

If you sign up for a Hatha yoga class, you can expect many seated postures, some stretching and a focus on breathing and meditation. The class tends to be less vigorous than other types of yoga classes, but is a good place for beginners and for those looking for a relaxing, not strenuous, experience.

If you're looking for an intense, physically demanding yoga practice or to use yoga for weight loss, Hatha yoga may not be for you.
