Wheeled exerciser

A wheeled exerciser comprising:

• a housing;
• an axle rod extending through said housing;
• two traction wheels rotatably supported on said axle rod, said traction wheels extending through a bottom of said housing;
• a first spring fixedly connected to one of said traction wheels and to said housing wherein said first spring is a torsion spring having a first end connected to said one of said traction wheels, a helical portion that winds around said axle, and a second end connected to said housing via a plate that is fixedly connected to said housing;
• a front auxiliary wheel rotatably mounted to said housing at a position in front of said axle rod;
• and
• a rear auxiliary wheel rotatably mounted to said housing at a position behind said axle rod.

A wheeled exerciser, comprising:

• a housing means for packaging at least an upper visible portion of the exerciser;
• an axle rod extending through said housing means;
• two traction wheels rotatably supported on said axle rod, said traction wheels extending through a bottom of said housing;
• spring means attached between said traction wheels and said housing, wherein said spring means includes at least one torsion spring having a first end connected to said one of said traction wheels, a helical portion that winds around said axle, and a second end connected to said housing via a plate that is fixedly connected to said housing
• a front auxiliary wheel rotatably mounted to said housing at a position in front of said axle rod, and means for allowing said front auxiliary wheel to rotate freely;
• and
• a rear auxiliary wheel rotatably mounted to said housing at a position behind said axle rod, and means for allowing said rear auxiliary wheel to rotate freely.

A method of exercising the abdominal region, comprising:

• i) providing an exerciser having:
• a) a housing;
• b) an axle rod extending through said housing;
• c) two traction wheels rotatably supported on said axle rod, said traction wheels extending through a bottom of said housing;
• d) a first spring fixedly connected to one of said traction wheels and to said housing;
• e) a front auxiliary wheel rotatably mounted to said housing at a position in front of said axle rod;
• and
• f) a rear auxiliary wheel rotatably mounted to said housing at a position behind said axle rod;
• ii) having a user grasp handles extending from opposite sides of said housing while kneeling on a ground surface and then lean forward such that said traction wheels roll along the ground surface and return resistance force is applied via said first spring while said front and rear auxiliary wheels roll freely along the ground surface.

A method of exercising the abdominal region, comprising:

• a housing, the housing comprising:
• an axle rod extending through said housing and acting as a handle;
• two traction wheels rotatable supported on said axle rod, said traction wheels extending through a bottom of said housing;
• a first spring fixedly connected to one of said traction wheels and to said housing;
• a front auxiliary wheel rotatably mounted to said housing at a position in front of said axle rod;
• a rear auxiliary wheel rotatably mounted to said housing at a position behind said axle rod;
• wherein said housing further comprises:
• generally flat left and right sides having a generally central opening for a handle;
• a generally cylindrical top wall extending over said traction wheels and having a slightly larger diameter than said traction wheels;
• and a front extension extending over the front auxiliary wheel and a rear extension extending over the rear auxiliary wheel;
• and
• grasping the handle while kneeling on a ground surface
• leaning forward such that said traction wheels roll along the ground surface, while return resistance force is applied via said first spring while said front and rear auxiliary wheels roll freely along the ground surface.
