I don't know how many times I see practitioners lackadaisically transition from one standing posture to the next. The transition of the standing posture is the gateway to a dynamic Trikonasana or Parsvottanasana. Transitioning between the postures needs to be panther like and full of expression. When done correctly you can soar through the air, be poised to land lightly, and have your body fully prepared for your standing posture. The child like spring that happens adds an additional amount of enjoyment to your practice. So the next time you are jumping into Uttitha Parsvakonasana really spring like a tiger and fully express yourself. Enjoy!
