From limited experience I know improving my quad strength would really help when it comes to backcountry descents carrying touring kit.
I've seen some generic quad exercises for skiiers along the lines of squat-a-bit-and-hold-the-position.
I'm wondering whether these need adapting for skiing with a pack though?
Specifically how far down should I be squatting and how far forward should I be leaning?
(It doesn't help that my skiing technique is pretty blunt so I'm not sure what the answer to those questions should be during the actual descent either lol. Though my general impression is that to feel in control I always need more squat and more lean than my body is ready to deliver...)
