         4 . The exercise bench according to  claim 1 , wherein the recess comprises a first recess and a second recess, wherein the first recess and the second recess are respectively opened in the shields ( 3 ) on the two sides of the deck ( 2 ), and the pull cable steering mechanisms comprise a first support ( 9 ) corresponding to the first recess and a second support ( 10 ) corresponding to the second recess, the first support ( 9 ) and the second support ( 10 ) being respectively provided with a first winding structure and a second winding structure. 
     
     
         5 . The exercise bench according to  claim 4 , wherein top portions of the first support ( 9 ) and the second support ( 10 ) are connected to form an integral structure. 
     
     
         6 . The exercise bench according to  claim 4 , wherein the first winding structure is provided with a first locking member, and the first winding structure is slidably connected to the first support ( 9 ) and a position of the first winding structure relative to the first support ( 9 ) is fixed via the first locking member; the second winding structure is provided with a second locking member, and the second winding structure is slidably connected to the second support ( 10 ) and a position of the second winding structure relative to the second support ( 10 ) is fixed via the second locking member. 
     
     
         7 . The exercise bench according to  claim 4 , wherein the first support ( 9 ) and the second support ( 10 ) are telescopic rods each with a fastener device. 
     
     
         8 . The exercise bench according to  claim 4 , wherein the first winding structure and the second winding structure are universal pulleys. 
     
     
         9 .
