And that's precisely where we'll realize the greatest benefit from pure round turns. It works like this. No matter how steep a slope you are on, when you are traversing across it, it's as though you were skiing on a gentler pitch at a gentler angle. And of course, you speed up. Skiers can always feel this sudden acceleration as they turn down the hill.
Beginners feel it their fist day on skis.
And I know you do too. So having just accelerated, the question now becomes how to slow back down. Both choices slow you down, but in completely different ways. When you skid sideways across the snow, you are using your legs as shock absorbers to scrub off speed, digging into the snow, resisting your speed by tensing your leg muscles. On the other hand, if you can avoid skidding altogether, and instead get your skis to follow a round line in the snow, something very different happens.
