Exercise platform

Abstract

An exercising device having a base platform with a foot restraint proximate to a first end. The platform is adapted to support an inflatable bladder proximate to a second end. The foot restraint is disposed above a top surface of the platform and extends across a portion of the platform. In use, a user may support a portion of their torso on the semi-hemispherical inflatable bladder and place one or both feet beneath the foot restraint(s).

What is claimed is: 
     
         1 . An exercise device, comprising;
 an elongated platform having a length between first and second ends greater than a width side-to-side, said platform having an upper surface and a lower surface, wherein said lower surface is adapted for resting on a support surface;   a foot restraint supported above said platform and extending over at least a portion of the width of said platform, wherein said foot restraint is disposed proximate to said first end of said platform; and   an inflatable bladder having an resilient top surface and a base, wherein said base is disposed on said top surface of said platform proximate to said second end of said platform.   
     
     
         2 . The device of  claim 1 , wherein said resilient top surface of said inflatable bladder is generally semi-hemispherical, when inflated. 
     
     
         3 . The device of  claim 1 , wherein said base of said inflatable bladder is substantially rigid and is fixedly connected to said platform. 
     
     
         4 . The device of  claim 1 , further comprising;
 one or more relief recesses extending across at least a portion of the width of said platform, wherein said relief recesses are disposed along the length of the platform between said foot restraint and said inflatable bladder.   
     
     
         5 . The device of  claim 1 , further comprising:
 a slide mechanism disposed between said base of said inflatable bladder and said base platform.   
     
     
         6 . The device of  claim 1 , further comprising:
 a frame attached to said bottom surface of said platform.   
     
     
         7 . The device of  claim 8 , further comprising:
 one or more tension cables disposed within said fame and each having:
 a first end connected to said platform proximate to said first end of said frame; 
 a second end connected to at least one spring, wherein said spring is connected to one of said frame and said platform proximate to said second end of said platform. 
   
     
     
         8 . The device of  claim 8 , further comprising an adjustor for adjusting tension in said spring or cable. 
     
     
         9 . The device of  claim 1 , wherein said foot restraint is integrally formed with said platform. 
     
     
         10 . The device of  claim 1 , further comprising:
 first and second adjustors attaching said foot restraint to said platform, wherein said adjustors allow selectively adjustment of a height of said foot restraint.   
     
     
         11 . An exercise device, comprising;
 an elongated platform having a length between first and second ends greater than a width side-to-side, said platform having an upper surface and a lower surface, wherein said lower surface is adapted for resting on a support surface;   a foot restraint supported above said platform and extending over at least a portion of the width of said platform, wherein said foot restraint is disposed proximate to said first end of said platform; and   a recessed surface in said top surface of said platform disposed proximate to said second end of said platform, wherein a periphery of said recess corresponds with a periphery of a base of an inflatable bladder.   
     
     
         12 . The device of  claim 11 , wherein said recess further comprises an overhanging lip about at least a portion of its periphery. 
     
     
         13 . The device of  claim 12 , further comprising:
 an inflatable bladder having an resilient top surface and a base, wherein said base extends peripherally from said bladder and is sized for conformal receipt below said overhanging lip.   
     
     
         14 . The device of  claim 11 , further comprising;
 one or more relief recesses extending across at least a portion of the width of said platform, wherein said relief recesses are disposed along the length of the platform between said foot restraint and said inflatable bladder.
