Original sentence: During any carved turn on a sufficiently steep slope, the perceived g-force will build up at the end of the carve, resulting in a natural compression of the body.Extreme Carving or Extremecarving is a coined term describing a particular form of carving on a snowboard.Features of extremecarving that distiguish it from other kinds of snowboard carving include:.Full extension of the entire body during the middle of the carved turn, when the snowboard is facing down the fall line of the slope.In contrast, most other styles indicate that one should face the nose of the board at all times, face in the direction of the snowboard bindings, or face the fall line at all times.Large, progressive rotation of the upper body in the turning direction, such that the rider's chest is facing the toeside edge of the board during frontside carves and the nose of the board during backside carves.Proactive compression of the body during edge transitions.This maneuver is also known as a cross-under turn.This maneuver is differentiated from this natural compression in that it is done by pulling the legs up in anticipation of the additional force, instead of allowing the upper body to fall down as a reaction to the additional force
Edited sentence: A form of snowboarding which involves carving (turning in a curved manner) neat lines down slopes.The "extreme" prefix is subjective and all carving, whether seen as "extreme" or not should just be called "carving" for simplicity and clarity
