And the yoga keeps coming

This is info from a regular email list I am on. I think someone is trying to encourage my new slight obsession...

(1) HATHA. In the U.S., most styles tend to fall within this category. There are 3 basic elements in hatha yoga: postures, breathing techniques and meditation techniques. (2) IYENGAR. In this type of yoga, the individual concentrates on the numerous body alignments needed to achieve and hold any one posture. (3) ASTANGA. A rigorous form of yoga, astanga requires continuous movement between postures, without pausing or rest. (4) BIKRAM. A sort of “hothouse” approach to yoga, this type of yoga is practiced in a room with the temperature raised. Bikram involves an extensive series of postures that stretch the muscles in a precise sequence. (The increased room temperature is intended to raise body heat even further, in order to make the muscles warmer and easier to stretch.)
