Snowboard Iskola

hey i know that i am supposed to have my shoulders in line with my board, hips and knees and i have been working on it for a while, but i still do the same thing and i just cant keep my shoulders aligned with the board, i naturally turn them downhill, is there any drills or techniques i can use to fix this problem and force myself to keep them perallel to my board, it is a very annoying problem because i cant straight line without the board catching edges.
