Seems like you may be waiting around for the right “tip” that finally resonates and boom, you’re in perfect skiing position. Doesn’t work like that in most sports including slalom unfortunately. Luckily in this case, as opposed to throwing a slider or knuckleball properly we are simply talking about executing “standing up”. The result is easy to conceptualize and there are no tricks to it, really.
At the end of the day, executing it is work, mental and physical and it's over a determined period of time. It’s putting a process in place with a feedback loop over the entire next summer. Being determined that this is the truth and the way and asking yourself if you did it every set. It’s easy to do behind the boat just standing there, so do it in the move out, then the glide, then the turn in, then the turn, then ball to wake, etc. bit by bit. As Scoke said the overarching concept is lean+resist vs. squat+pull.
