Your happiness doesn't have anything to do with how you look, it's how you feel. Having pretty butt-cheeks is superficial. What this planet needs is a little healing balm and a Band-aid. The most popular schools of yoga are Iyengar, Astanga, Kundalini and Sivanda. Iyengar yoga pays detailed attention to the position and alignment of each body part, especially in the standing poses.
Astanga classes link each pose with a flowing movement called a vinyasa.
This continuous movement creates intense heat which detoxifies the body and renders it more pliable. A variation on traditional Astanga is called Power Yoga. Kundalini yoga focuses less on generating heat and more on breathing techniques, chanting and meditation. Its goal is to awaken kundalini, the dormant energy at the base of the spine, in order to increase vitality and attain enlightenment. Sivananda yoga is a traditional system of hatha yoga which follows a format similar to Kundalini.
