Reverse Carve to Spin.

1. First, make sure you can carve in your switch stance (your normal back foot leading) with both turns equally solid and the same depth.

   If the base switch carve is shaky, the edge skips around before you can load up the rotation.

2. On a gentle to medium slope, enter your switch carve at a calm, controlled medium speed.

   Press the shin of your leading (switch-front) foot from the ball of the foot into the front of the boot (the tongue), bend both knees to about 70-90 degrees, and stay low. Point your pelvis square down your switch direction of travel and look toward the exit of the arc.

3. Pick the exit of a toe-edge turn to spin out of.

   Once you have tipped the board onto the toe edge and passed the peak of the arc, just before you release the edge, send only your leading shoulder and your eyes in the direction you want to spin and wind up the upper body. Keep the board (lower body) still for now and let the upper body lead.

4. At the exit of the arc, push off the toes of both feet to stand up, and as you release the edge, unwind the upper body you loaded.

   Let the lower body chase the upper body around and lift the board light off the snow to start spinning. Aim to change the board's direction in that one light moment, not by scraping it around on the snow.

5. For a 180, the board lines up with your regular stance (your normal front foot leading) at the halfway point.

   To avoid over-rotating, stop your eyes on the landing direction early once you start turning, then bend both knees and set the edge in gently from a low stance.

6. After you land, flow straight into a regular carve, drawing one turn's worth of arc so the whole move reads as a single line.

   Don't let the spin end as an isolated point; link it smoothly with the carve before and after.
