Spontaneous symmetrical weight shifting trainer device

A stationary exercise device comprising:

• (a) a first support member for a first pivoting element attached to a first rotational resistance component and second supporting member for a second pivoting element attached to a second rotational resistance component, each first and second support member having a transverse axis for each rotational resistance component and a vertical pivot axis, and each first and second support member pivots about each vertical pivot axis;
• (b) a first foot tread member and second foot tread member, each first and second foot:
• tread member having a front and rear end, each first and second foot tread member front end traveling in an arcuate path about each transverse axis;
• and
• (c) as each support member pivots inward, a prescribed reciprocating arcuate path of the front ends of each respective first and second foot tread member is imposed that remains parallel to a plane of rotation of the rotational resistance component.
• (d) to alter a plane defined by rotation of the front end of each tread member a first plane

A stationary exercise device comprising:

• (e) a first support member for a first pivoting element attached to a first rotational resistance component and second supporting member for a second pivoting element attached to a second rotational resistance component, each first and second support member having a transverse axis for each rotational resistance component and a vertical pivot axis, and each first and second support member pivots about each vertical pivot axis;
• (f) a first foot tread member and second foot tread member, each first and second foot tread member having a front and rear end, each first and second foot tread member front end traveling in an arcuate path about each transverse axis;
• and
• (g) as each support member pivots inward, a prescribed reciprocating arcuate path of the rear ends of each respective first and second foot tread member is imposed changes between a longest path defining a tread movement plane parallel to a plane of rotation defined by a respective rotational resistance component and a fixed stationary point for the respective rear end.

A stationary exercise device comprising;

• (a) a frame member having a transverse pivot axis defined relative to the frame member;
• (b) a first foot tread member and a second foot tread member, each first and second foot tread member having a front end, a rear end, and two sides, each first and second foot tread member front end operatively associated with a coupling member for pivotally coupling the front end of each first and second foot tread member to the transverse pivot axis at a predetermined distance from the transverse pivot axis, so that each first and second foot tread member front end travels in an arcuate path about the transverse pivot axis, a pair of wheel members disposed for rotation about the transverse pivot axis, each coupling member comprising a bell crank, each bell crank disposed so as to rotate with at least one wheel of said pair of wheels, a first end of each bell crank pivotally connected to the front end of a respective one of the first and second foot tread members, each first and second foot tread member moving independently of the other of said first and second foot tread member, each first and second foot tread member moving along a line between the tread member front end and rear end, each first and second foot tread member rear end operatively associated with a glide member for moveable coupling of the rear end of each first and second foot tread member to the frame member, to direct each first and second foot tread member rear end along a reciprocating path of travel as each first and second foot tread member first end travels in an arcuate path;
• (c) whereby when the exercise device is in use, and when the rear end of each first and second foot tread member travels along the reciprocating path of travel in a direction away from the pivot axis, the toe portion of the user's foot associated therewith initially lowers at a rate faster than the heel portion of the user's foot, and when the rear end of each first foot tread member and second foot tread member travels along the reciprocating path of travel in a direction toward the pivot axis, the toe portion of the user's foot associated therewith initially rises at a rate faster than the heel portion of the user's foot.
