THE JUMP 180 IN A TERRAIN PARK
Many ski/snowboard areas have terrain parks which are a series of varying small hills, bumps
or moguls for performing jumps. The simple 180 is a fun, elementary jump. Approach the bump in a flexed (knees bent) position as shown in Photo 1. The rider in the photo sequence is riding goofy. Keep your hands wide apart so you have plenty of rotational inertia available for the counter rotating twist (Photo 2 ). Just as you leave the jump, counter rotate the upper body against the lower body (Photo 3). The lower body rotates clockwise looking down while the upper body remains in the original direction of travel. At the high point in the jump, the board should have rotated about 90 degrees (Photo 4).

As your center of mass begins to drop, continue counter rotating the upper body against the lower body to get the board at least generally in the direction of travel (Photo 5). Obviously, you don't want to land it at a 90 degree angle since that may result in a bad slam. Then land it with flexion of the knees and hips to absorb the shock of landing (Photo 6)
