"NIA Technique (knee-Ah), can be described as blending tai-chi, tae-kwon-do, ballet, jazz, modern dance, yoga and aikido. The result- graceful, fluid movements that are easy on the joints and skeletal system, combined with powerful, energetic motion that strenghtens and tones the entire body." i just found out about nia from a friend and started taking classes with her. it is sooooo awesome! check out this website... http://www.nia-nia.com/
