Lateral balance is where I’m really hurting right now, so I’ll work on that and try to forget this stuff for now
Some semi random thoughts for you, but applicable to every thread in this sub-forum I suppose:
It's always useful to overthink things that really interest you. As an adult learner I've made a point of educating myself as much as possible on all things skiing. Many of the higher level concepts I've absorbed don't have immediate application for me today but they are stored in memory for the time in the future when I can physically progress to the point of utilizing them. If you're an analytical geek, embrace it.
As an engineer you know that balance (in any direction) is simply a matter of positioning your COM over your BOS - dynamically. A good analog is balancing a rake or a broom on the tip of your finger (instead of raking the leaves like your Dad told you to do). With a little practice any kid can run around the back yard by moving his finger to control the direction of the rake. Note in this example there is zero input at the head of the rake only the tip of the handle. Skiers are different as they can move the upper body around as well as position their feet.
As an adult learner you will need a really big base of support to keep from falling over. But as your body starts to learn the movement patterns, the corrections needed to keep upright become smaller and more adaptable to rapid changes in terrain. You will learn to anticipate where you will need to be in order to navigate the slope instead of just reacting to it.
A major goal for any new skier is to be able to split that base of support into a left / right footed model with a seamless transition between the two. Skiing is a one footed sport. I've been working on improving my technique for 7 years and every year I've increased my understanding of just how true that statement is. It's the Swiss Army knife of your skiing toolbox and works (almost) in every situation,
If you stay on easy terrain for your practice sessions you can keep your brain out of survival mode and away from the fear of falling. Rather than contemplating your imminent destruction your brain can think and your body can feel how the pressure and movement of your skis is affecting travel down the slope. Learn how to learn, become aware of the obvious inputs that come from your body. Can you feel your shin touching the cuff of your leg (good). Are you staring at the tip of your skis all the time (not good).
Watch other skiers on your chair rides up the hill. What looks good to you? Can you figure out what the good skiers are doing or not doing? Perhaps not quite skiing specific but have you ever marveled at how the general public can discern between good and bad performance in any sport without ever directly experiencing it first hand? We have an innate appreciation for strong dynamic movement brought on with seemingly minimal effort. To me that is what drives my enjoyment on the mountain.
