Abstract
An abdominal exercise apparatus can include a track, at least one rolling member, a cart, and a base. The track can extend between first and second ends. The rolling member can be moveable along the track. The cart can support the rolling member for the movement along the track and be grasped by the user during exercise. The base can be engaged proximate to the first end and have a surface configured to receive the knees of the user during exercise. The second end can be pivotally movable about the base over an arcuate range by the user while exercising during the rectilinear and rolling movement along the track by the at least one rolling member. The apparatus can also include a structure such as a helical spring for resisting pivotal movement that is elastically deformable.
Claims22
An abdominal exercise apparatus comprising:
- a track extending a length between a first end and a second end;
- at least one rolling member rectilinearly moveable along said track between said first end and said second end by a user during exercise;
- a cart supporting said at least one rolling member for the rectilinear and rolling movement along said track and said cart having a portion configured to be grasped by the user during exercise;
- a base engaged with said track proximate to said first end of said track and having at least one surface configured to receive first and second knees of the user during exercise, wherein said second end of said track is pivotally movable about said base over an arcuate range by the user while exercising during the rectilinear and rolling movement along said track by said at least one rolling member;
