I'd like to hear from someone who is more of an advanced downhill skier, like someone who has competed in slalom or mogul events, or is a veteran back-country skier.
Is there a template program you followed to become a stronger skier, something suggested to you by a coach or a personal trainer?
Is there a specific muscle group in your core or lower body you would suggest focusing on?
It can be either for moguls, slalom, glades, back country, whatever I like all kinds of skiing. I'm already a good skier, I just want to become better, and I think being physically stronger in the right places can help just as much as going out on the mountain and putting a bunch of hours in.
This is not a duplicate of this question which is the closest I could find, because this post just talks about someone with knee problems.
