A long time ago, about 1988 I think, Chris Karol produced an instructional video with that title. The simple wisdom was do not bend over at the waist and reach down for the snow. The boards had notches in the tails and the boots looked like something out of LL Bean. We've come a long way, but this one nugget of advice is still relevant today.
Beginner or intermediate carvers whose primary goal is to "get low" or "touch the snow" will most likely teach themselves the bad habit of bending over at the waist. They will need to unlearn it later in order to progress past intermediate ability, and this will be more difficult than avoiding this problem from the start.
I saw this youtube in the videos forum and had to point this out. The guy in the full black-and-white patterned outfit is a prime example of what happens when a beginner carver tries to touch the snow, above all else. 0:52 and other places.
I would recommend to him and anyone else at this stage to stand up, bend the knees, keep the shoulders level to the hill, keep the head upright, move to gentler slopes, and learn to absorb terrain and manipulate the board and its energy with the knees and ankles. In time, the ground will come up to meet your hand, hip, thigh, armpit, etc, without you even trying.
