Exercise device

Abstract

An exercise device may include a main body defining an arch-shaped structure, at least one movable support mechanism coupled to the main body and configured to support the exercise device on a support surface, and at least one gripping mechanism coupled to the main body. The main body may be formed from a shape retaining material. The exercise device may further include a biasing mechanism coupled to the main body. The at least one movable support mechanism may include wheels coupled to the main body. The at least one gripping mechanism may include a handle or a recess or an elongated slot formed in the main body. The main body may further include apertures for joining the handle to the main body at various positions.

What is claimed is: 
     
         1 . An exercise device, comprising:
 a main body comprising a material that maintains a predetermined shape of the main body in the absence of an applied force by a user on the main body and that allows the predetermined shape of the main body to change upon application of a force by the user;   at least one movable support mechanism joined to the main body and configured to support the main body on a support surface; and   at least one gripping mechanism operatively associated with the main body and configured to allow the user to apply the force to the main body.   
     
     
         2 . The exercise device of  claim 1 , wherein the material comprises spring steel. 
     
     
         3 . The exercise device of  claim 1 , wherein the material resists changes to the predetermined shape and returns to the predetermined shape upon removal of the force applied by the user. 
     
     
         4 . The exercise device of  claim 4 , wherein the predetermined shape comprises an arch-shaped structure. 
     
     
         5 . The exercise device according to  claim 1 , wherein
 the arch-shaped structure includes an upper side, an underside, a first edge, and a second edge distal the first edge;   the upper side defines a convex surface of the arch-shaped structure;   the underside defines a concave surface of the arch-shaped structure; and   the first edge and second edge define two distal ends of the arch-shaped structure and a length dimension of the arch-shaped structure.   
     
     
         6 . The exercise device of  claim 5 , wherein the at least one movable support mechanism comprises a plurality of wheels coupled to the underside of the main body proximate to one of the first and second edges of the main body. 
     
     
         7 . The exercise device of  claim 6 , wherein at least one of the plurality of wheels is coupled to the underside of the main body via a pair of brackets and an axle supported by the pair of brackets. 
     
     
         8 . The exercise device of  claim 6 , wherein the plurality of wheels are coupled to the underside of the main body by a common axle. 
     
     
         9 . The exercise device of  claim 6 , wherein the at least one movable support mechanism is coupled to one of the first and second edges of the arch-shaped structure such that the one of the first and second edges of the arch-shaped structure does not contact the support surface. 
     
     
         10 . The exercise device of  claim 5 , wherein the at least one gripping mechanism comprises at least one handle coupled to the upper side of the main body. 
     
     
         11 . The exercise device of  claim 10 , wherein the at least one handle is removably coupled to the main body by at least one fastener, and the main body further comprises at least one aperture configured to receive the at least one fastener therein. 
     
     
         12 . The exercise device of  claim 5 , wherein the at least one gripping mechanism comprises at least one recess at one of the first and second edges of the main body. 
     
     
         13 . The exercise device of  claim 5 , wherein the at least one gripping mechanism comprises at least one elongated slot formed in the main body proximate one of the first and second edges of the main body. 
     
     
         14 . The exercise device of  claim 5 , further comprising a biasing mechanism joined to an underside of the main body. 
     
     
         15 . The exercise device of  claim 14 , wherein the biasing mechanism comprises at least one elastic band. 
     
     
         16 . The exercise device of  claim 14 , wherein the predetermined shape comprises a substantially flat plate-like structure, and the biasing mechanism causes the main body to form an arch-shaped structure.
