(under subclass 51) Subject matter wherein significance is attributed to conditioning or developing a muscle employed as the user rides a pair of long, flat, foot-attached runners and glides over a land or water surface while being propelled primarily by an external pulling force, e.g., gravity, a
pulling vehicle, etc., or operates apparatus which simulates such riding and gliding.
(1) Note. The user generally only provides insignificant propelling thrust, e.g., for starting down a ski slope, for positioning prior to, or immediately after, skiing down a ski slope, etc. Nordic (cross country) skiing, or the simulation thereof, which involves significant user generated propulsion, is thereby excluded from this subclass. If a patent related to skiing exercise is silent as to the type of propulsion involved, it may be placed in this subclass, if not provided for in a subclass above.

66+, for an occupant propelled support frame having a movement facilitating feature and which may be used when skiing or simulating skiing.
69, for apparatus for suspending an occupant from above, e.g., a body harness, etc., which may be used when skiing or simulating skiing.
70, for apparatus having separate foot engaging members for reciprocating on parallel guide tracks in a manner similar to Nordic (cross country) skiing.
146, for a swivelled foot platform which supports the entire body of the user. SEE OR SEARCH CLASS
