To side slip point both skis directly across the hill. Your boots should be following a line straight down the hill. They may also try the leaping and foot shuffle exercises described for the level 1-4 skiers but do them while making a turn . The skier extends their legs using their own energy and the bump itself to get propelled up into the air where the new turn is initiated. The skier is taking off at the end of one turn and landing in the beginning of the next.
Transition occurs while airborne.
The skiers velocity is kept close to constant without excessive slowing down during the slipping portion of the exercise. These should be done in a series of 3-10 swings in both directions. In addition to focusing on centered stance, side slips, hockey slips, and pivot slips place increasingly more and more importance on good upper-lower body separation and proper flexing and extending of the legs. It helps to use both feet . Again, this sounds simple enough but you would be surprised.
