Start by standing on a groomer with your feet slightly wider than shoulder-width apart. Pressure the downhill ski and point your downhill kneecap towards the tip of your uphill ski. Now, try this while making wide, fast turns (above). This drill exaggerates the change in pressure on your downhill ski and helps you get a feel for both kneecaps pointing towards the uphill ski, eventually leading to a clean carve.
As you get the hang of it, decrease the length of your turns and the width of your stance to shoulder-wide until you feel comfortable making very short-radius turns. At this point, you’ll be ready to transfer your carving abilities to the moguls (above and next image).
By carving in the bumps, you’ll be using the power and rebound of the ski, making it easier to move smoothly and energetically down the fall line.
