       8 . The exerciser as claimed in  claim 7 , wherein said locking member is a lock screw.  
   
   
       9 . The exerciser as claimed in  claim 1 , wherein said at least one weight holder each has two support rods symmetrically disposed at two sides thereof for holding said weights.  
   
   
       10 . The exerciser as claimed in  claim 1 , wherein said at least one roller each is respectively supported on said guide rail by a respective universal joint ball bearing so that said at least one roller is respectively tiltable relative to an axis of said guide rail.  
   
   
       11 . The exerciser as claimed in  claim 1 , wherein said at least one grip each has two extension rods disposed at two sides for holding said weights.  
   
   
       12 . An exerciser comprising: 
 a frame;    two weight holders movably supported on said frame;    two cord members each having a first end respectively connected to said weight holders and a second end;    two grips respectively fastened to the second ends of said cord members; and    a plurality of weights detachably mounted on said weight holders.    
   
   
       13 . The exerciser as claimed in  claim 12 , wherein said frame comprises a base, two uprights connected to said base, two posts connected to said base, and two transverse bars respectively fastened to said uprights and said ports.  
   
   
       14 . The exerciser as claimed in  claim 13 , further comprising two brackets respectively provided at said posts, said brackets each comprising a locating rod respectively pivoted to said posts, two hooks, two side rods respectively connected between said locating rod and said two hooks, and a gap defined between said two hooks for the passing of said cord members for enabling said cord members to be respectively inserted through said brackets.  
   
   
       15 . The exerciser as claimed in  claim 13 , further comprising a guide rail connected between said transverse bars, and two rollers supported on and movable along said guide rails for guiding said cord members.  
   
   
       16 . The exerciser as claimed in  claim 15 , wherein said rollers are respectively moveably supported on said guide rail by a universal joint ball bearing so that said rollers are tiltable relative to an axis of said guide rail.  
   
   
       17 . The exerciser as claimed in  claim 13 , further comprising two guide pulleys respectively pivoted to connection areas between said uprights and said transverse bars for guiding said cord members, said guide pulley being biasable relative to said uprights.  
   
   
       18 .
