The recoil or spring effect when decambered (bent backwards) skis (due to turning forces) are "released" and bounce back into its natural position.

Of the legs up under the body. Used to avoid sudden pressure increases due to terrain changes or turning. Also to avoid obstacles or terrain changes, such as moguls.

Reverse camber
When a great deal of pressure is applied to a ski, the ski will lose its natural arch, or camber, and will distort into the opposite direction, bowing downwards in the mid-section, rather than upwards. This aids turning, and also gripping.

Running groove
The long groove cut into the base of most skis to allow straight running and stability at speed.

Russian dance
A classical double-pole push followed by one to four skate steps prior to the next pole action, as a method a relaxing the upper body. Can be used with half skating.
