Seat attachment for exercise devices

Abstract

The present invention discloses an exercise device wherein a user exercises the abdominal muscles and/upper body strength training by throwing a ball into a ball shoot or against a rebound surface. The user places back on a horizontal fixed back rest portion and buttocks on a pivotal seat and feet on an adjustable device provided for securing the feet. Springs provides shock dissipation while the user catches ball in a downward position. The user throws ball in an upward movement into a ball shoot retrieving ball located at bottom ball ramp.

         8 . An exercise device seat attachment according to  claim 3 , wherein said main body is adjustably attachable to the exercise device.  
     
     
         9 . An exercise device seat attachment according to  claim 8 , further comprising a pin selectively engageable with one or more holes formed in the exercise device.  
     
     
         10 . An exercise device seat attachment according to  claim 3 , said hole adapted to allow a stability ball to pass completely therethrough.  
     
     
         11 . An exercise device, comprising: 
 a main frame;    at least one part selectively user-movable with respect to a second part for exercise purposes;    a substantially ring-shaped support attached to said main frame having a center hole adapted to receive a conventional stability ball,    wherein when a stability ball is placed in said center hole, a user may sit or stand on the stability ball in said center hole and move said selectively user-movable part with respect to said second part.    
     
     
         12 . An exercise device according to  claim 11 , said hole adapted to receive a stability ball without allowing the stability ball to pass completely therethrough.  
     
     
         13 . An exercise device according to  claim 11 , wherein said hole is substantially round.  
     
     
         14 . An exercise device according to  claim 11 , wherein said hole is substantially polygonal.  
     
     
         15 . An exercise device according to  claim 11 , further comprising a sleeve disposed around said support having a relatively high coefficient of friction.  
     
     
         16 . An exercise device according to  claim 11 , wherein said support is adjustably attachable to said main frame.  
     
     
         17 . An exercise device according to  claim 16 , further comprising a pin attached to one of said support or said main frame selectively engageable with one or more holes formed in the other of said support or said main frame.  
     
     
         18 . An exercise device according to  claim 11 , said hole adapted to allow a stability ball to pass completely therethrough.  
     
     
         19 . An exercise device, comprising: 
 a main frame;    at least one part selectively user-movable with respect to a second part for exercise purposes;    a user support having: 
 an attachment portion movably attachable to said main frame;  
 a lower curved surface unstably engaging the floor; and  
 an upper support surface supporting a user while the user moves said selectively user-movable part with respect to said second part.  
   
     
     
         20 . An exercise device according to  claim 19 , wherein said attachment portion is pivotably attached to said main frame about an axis.  
     
     
         21 . An exercise device according to  claim 19 , said user support further comprising: 
 a substantially rigid top platform incorporating said upper support surface; and    a flexible substantially hemispherical body attached to an underside of said top platform incorporating said lower curved surface.    
     
     
         22 . An exercise device according to  claim 21 , said attachment portion being attached to said top platform.  
     
     
         23 . An exercise device according to  claim 19 , said user support further comprising: 
 a substantially rigid top platform incorporating said upper support surface; and    a substantially cylindrical lower body attached to an underside of said platform incorporating said lower curved surface.    
     
     
         24 . An exercise device according to  claim 23 , said attachment portion being attached to said cylindrical lower body.  
     
     
         25 . An exercise device user support, comprising: 
 an attachment portion movably attachable to a main frame of an exercise device having at least one part selectively user-movable with respect to a second part for exercise purposes;    a lower curved surface unstably engaging the floor; and    an upper support surface supporting a user while the user moves the selectively user-movable part with respect to the second part.
