after reading about it a lot here (esp. from snowolf), I consciously tried to keep my shoulder pointed down the mountain and my upper body upright and quieter while moving my legs/board around this weekend. today, my core feels sore - not bad, just...sore. and a bit more worked out than my legs, which are usually more sore. am I right in assuming this means I'm headed in the right direction? obviously hard to say without video, but any thoughts are appreciated!
