So on 1 you are leaning forward, front leg more bent than back leg? If your shoulders and knees are parallel to board, wouldn't they be parallel with the terrain like in number two? I am not trying to argue just trying to distinguish the difference between points one and two.
Seems like I start out having the same problem every year...I switch from toe to hill fine but when I go to switch from hill to toe I fill like I am doing more with my rear leg...this problem seems to go away after about the third time out, but I don't understand why it a problem in the beginning every year. That why I was some what interested in this thread.
1.) is about how you are lined up side ways to your front foot. The lenth of you front foot is the top of a T and your knees/hips/shoulders are the stem of the T. Depending on the angle of your front foot your body will be pointed between the nose and heelside of the board. For teaching purposes it is easier to imagine being able to squat down and grab your nose and tail of your board with your hands. It really isn't about knee bend more or less between feet. Another way to0 think about it is if your board was a box your body would stay within the box(typically).
#2 is about knee bend typically. Think about having 4 checker boards. bottom layer is your board flat on the snow. The next three levels are your knees, hips, and shoulders. They should all be parallel. If in my example your lead hand is higher then your backhand when making the T it indicates that your front leg is straighter then your back leg which mean you have more weight on the back leg which effect the third reference alignment.
The problem you're having is that because your out of the reference alignment and on your back foot you are only steering with the back of the board. It is like trying to turn a car with your front wheels of the ground. One trick to try is to pretend that you are patting a midget on the head when turning toward your toeside, Then when you turn toward your heel you backhand him. Just remember he is short and you have to bend the front knee more to get to his level
One thing to remember is the above alignments are that you don't stay in them at all times. But you usually start or end in it.
P.S. Trust that your board will turn when you start the turn movement with your front foot. also remember to look across the hill and almost back up it so that you complete the turn and don't stop your rotation and it will come back quickly. If you need more just let me know.
