Parivritta Trikonasana (Revolved Triangle)
The revolved triangle takes all of the aspects of trikonasana and spins them around, challenging ones balance; poise and ability to remain centered and focused. Imagine taking a structure and turning it on its side, or upside down. In a sense the triangle would look the same no matter what side you laid it on.
That is the challenge and the benefit of revolved triangle, to maintain that sense of the trinity well balanced, properly focused and integrated. Because in effect it is also a twist you have the added benefits of twists, which are excellent for lower back pain, for healthy digestion and function of the lower abdomen as well as the effects of turning oneself upside down, which strengthens the central nervous system.
