Exercise device

Abstract

An exercise device has a central elastic portion and a pair of cuff portions. The central elastic portion has an elastic band of a predetermined tension. Each of the cuff portions is removably attached to one end of the central elastic portion, and each of the cuff portions includes a backing strip having two Velcro portions. The Velcro attachment allows the cuffportions to be securely and removably attached to a portion of the user's body, such as the user's ankles. A variety of central elastic portions may be provided with bands having different lengths and elasticities, so that the user may select the band desired for a particular workout, and easily attach it to the cuff portions. The different bands are preferably color coded so that they may be easily distinguished and selected by the user.

What is claimed is:  
     
         1 . An exercise device comprising: 
 a first central elastic portion having an elastic band of a predetermined first length and predetermined first tension; and    a pair of cuff portions, each of the cuff portions being removably attached to one end of the central elastic portion, each of the cuff portions comprising a backing strip having two hook-and-loop portions whereby the cuff portion is securely and removably attached to a portion of a user's body.    
     
     
         2 . An exercise device as defined in  claim 1 , comprising in addition a second central elastic portion which may be removably attached to the cuff portions in place of the first central elastic portion.  
     
     
         3 . An exercise device as defined in  claim 2 , wherein the second central elastic portion has a predetermined tension which is different from the predetermined tension of the first central elastic portion.  
     
     
         4 . An exercise device as defined in  claim 2 , wherein the first and second central elastic portions are color coded to permit them to be easily distinguished from each other.  
     
     
         5 . An exercise device as defined in  claim 1 , comprising in addition a second central elastic portion which is removably attached to one of the cuffportions and to the first central elastic portion.  
     
     
         6 . An exercise device comprising: 
 a first central elastic portion having an elastic band of a predetermined first tension;    a second central elastic portion having a second elastic band of a predetermined second tension; and    a pair of cuff portions, each of the cuff portions being removably attached to one end of one of the central elastic portions, each of the cuff portions comprising a backing strip adapted to be wrapped around a portion of a user's body, the backing strip having two hook-and-loop portions whereby the cuff portion is securely and removably attached to the portion of the user's body.    
     
     
         7 . An exercise device as defined in  claim 6 , wherein the first and second central elastic portions are color coded to permit them to be easily distinguished from each other.
