         3 . The lever arm of  claim 2 , wherein the handle portion further includes a third handlebar transverse to both the first handlebar and the second handlebar, and wherein the first handlebar and the second handlebar are coupled at least in part by the third handlebar.  
     
     
         4 . The lever arm of  claim 2 , wherein the first handlebar is parallel to the second handlebar and wherein the first handlebar and the second handlebar are perpendicular to the first beam.  
     
     
         5 . The lever arm of  claim 2 , wherein weight attachment portion includes a barbell sleeve and wherein both the first handlebar and the second handlebar are substantially parallel to the barbell sleeve.  
     
     
         6 . The lever arm of  claim 1 , wherein the at least one handlebar includes a hollow portion configured to receive the at least one removable handle pin. 
     
     
         7 . The lever arm of  claim 1 , wherein the at least one removable handle pin is further configured to be magnetically coupled to the at least one handlebar.  
     
     
         8 . The lever arm of  claim 1 , wherein the first end further includes a handle cuff configured to at least partially surround the first beam and to be translated along the first beam, and wherein both the handle portion and the weight attachment portion are coupled to the handle cuff.  
     
     
         9 . The lever arm of  claim 8 , wherein the handle cuff includes at least one handle cuff wall including at least one second hole, and wherein the at least one removable handle pin is further configured to be inserted through the at least one first hole in the first beam, the at least one second hole in the handle cuff wall, and the at least one handlebar to releasably couple the handle portion to the first beam. 
     
     
         10 . The lever arm of  claim 8 , wherein the handle cuff defines an inner cavity and wherein the handle cuff is configured to receive the first beam within the inner cavity.  
     
     
         11 . An exercise device, comprising: 
 a handle cuff configured to at least partially surround a beam;   a weight attachment portion coupled to the handle cuff;    a handle portion coupled to the handle cuff and including at least one handlebar; and   at least one removable handle pin configured to be inserted through at least one hole in the beam and into the at least one handlebar to releasably couple the handle portion to the beam.    
     
     
         12 . The exercise device of  claim 11 , wherein the at least one handlebar includes a hollow portion configured to receive the at least one removable handle pin.  
     
     
         13 . The exercise device of  claim 12 , wherein the at least one removable handle pin is further configured to be magnetically coupled to the at least one handlebar.  
     
     
         14 . The exercise device of  claim 11 , wherein the weight attachment portion includes a barbell sleeve and wherein the at least one handlebar is substantially parallel to the barbell sleeve.  
     
     
         15 . The exercise device of  claim 11 , wherein the handle portion includes a first handlebar, a second handlebar, a first removable pin configured to be inserted through a first hole in the beam and into the first handlebar, and a second removable pin configured to be inserted through a second hole in the beam and into the second handlebar.  
     
     
         16 . A system, comprising: 
 an exercise rack including a first beam; and   a lever arm comprising: 
 an arm comprising a second beam, a first end, and a second end, the first end including a handle portion configured to be grasped by a user and a weight attachment portion configured to support at least one weight; and 
 a mount rotatably coupled to the second end of the arm, the mount configured to releasably couple the arm to the first beam of the exercise rack, 
 wherein the handle portion includes at least one handlebar transverse to the second beam and at least one removable handle pin configured to be inserted through at least one hole in the second beam and into the at least one handlebar to releasably couple the handle portion to the second beam.  
   
     
     
         17 . The system of  claim 16 , wherein the handle portion is configured to allow a user to unfix the handle portion from a first position along the second beam by removing the at least one removable pin, translate the handle portion along the second beam, and reaffix the handle portion to a second position along the second beam by reinserting the at least one removable pin.  
     
     
         18 . The system of  claim 17 , wherein the mount includes a mandrel assembly configured to allow the user to translate the mount along the first beam with a single hand of the user.  
     
     
         19 . The system of  claim 18 , wherein the mandrel assembly includes a mandrel pin biased toward the first beam.  
     
     
         20 . The system of  claim 19 , wherein the mandrel pin is biased toward the first beam by a spring.
