Counter motion isn't turning power, but it can be used in preparation for a turn. For instance, if the upper body is still, the lower body might be moving to the left or right. Or, if the upper body is moving to the left, then the lower body is either still or moving to the right. The upper-body movement doesn't effect the way the board moves on the snow. One form of counter motion is lower-body rotation, which occurs when the upper body is fairly stable in the fall line and the legs and board are turning.
Counter motion is also present at the beginning of the turn-initiation skill known as anticipation.
As the rider completes a turn with the lower body, he or she twists the upper body in the direction of the next turn, which stretches the muscles of the stomach and back. The turning power is produced when the body is forcefully realigned upon entry into the new turn. This movement option is useful in small-radius turns, steeps, flush slalom series, and chutes. With counter-rotation, the upper body's movement in one direction causes an opposing movement in the lower body. One of Newton's Laws of Physics states that for every action, there is an equal and opposite reaction.
