Turning is actually accomplished using rotation, edging and pressure (with balance maintained throughout) at the same time. A proper stance should be maintained with the hands up in front.
Introducing Direction Changes (To be done on a flat surface)
At this point, it is a good idea to return to the flat surface to work on the movements that will be used when making a turn. Have the athlete assume a snowboard stance, and practice going from the neutral, centered position into the position for a toeside turn and then back. Follow this by going from a neutral stance into the position for a heelside turn, and then back. Once the athlete has mastered the movements, introduce the idea of turning rhythm. The athlete will start in a neutral stance, go to a toeside position (count to 2), then back to center (count to 2), to a heelside position (count to 2) and back to center (count to 2, then repeat cycle).
NOTE: Extra time should be spent at this level to be sure that the athlete is comfortable before progressing.
