Ski Switch Riding.

1. Start stationary on a gentle slope.

   Keep your skis pointing where they are and turn only your upper body to look behind you. Rest your chin toward whichever shoulder you choose, left or right, and look back over that shoulder at the slope behind you. When riding backward, fear spikes the moment your eyes fall behind, so securing where you're going with your eyes comes first.

2. Once your eyes lead, twist your hips slightly toward that same shoulder.

   As your chest and belly button face the direction of travel, your legs follow on their own. Don't force the hips around. Let it unwind in order: shoulders, then belly, then legs.

3. Before you let the skis run, settle your weight evenly over the middle of both boots, roughly under the arch of each foot.

   Keep your shins lightly against the front of the boots so you don't tip forward, but keep your weight centered. This lets both skis slide the same amount and stops one from shooting ahead.

4. Let yourself drift straight down the fall line slowly.

   Riding backward, leaning onto the toes throws your upper body behind and makes you fall, so keep your weight slightly toward the heels and feel the heel of the boot supporting you.

5. Hold your poles loosely at your sides as balance support, not as something to swing.

   Big arm movements rock your upper body and you lose sight of where you're going.

6. To stop, make a backward snowplow (a wedge).

   Open the leading ends of the skis, the ends pointing where you're going (down the slope behind you), out to each side and press lightly to brush the snow. Get comfortable slowing down this way before you add turns.

7. When you add turns, weight the outside leg of the turn, the same rule as forward skiing.

   Left and right feel swapped and it's easy to get confused, so make one big turn at a time at a speed where you can still stop.
