         3 . The mount of  claim 1 , wherein the mandrel bar is configured to be pulled toward the mount handlebar by squeezing the mandrel bar and the mount handlebar together.  
     
     
         4 . The mount of  claim 1 , wherein the mandrel pin is biased toward the first position by a spring. 
     
     
         5 . The mount of  claim 1 , wherein the cuff further comprises a cuff crossbar including a second hole leading into the inner cavity defined by the cuff, and wherein the cuff crossbar is configured to allow a removable pin to be inserted through the second hole and into the inner cavity.  
     
     
         6 . The mount of  claim 5 , wherein a central axis of the hole within the cuff wall and a central axis of the second hole included in the cuff crossbar are perpendicular to one another.  
     
     
         7 . The mount of  claim 1 , wherein the cuff is configured to receive a beam of an exercise rack within the inner cavity defined by the cuff.  
     
     
         8 . The mount of  claim 7 , wherein the cuff is configured to at least partially surround the beam.  
     
     
         9 . The mount of  claim 7 , wherein the mandrel pin is configured to be inserted through one of a plurality of holes in the beam when the mandrel pin is in the first position.  
     
     
         10 . The mount of  claim 7 , wherein the mandrel pin is configured to be withdrawn from the beam when the mandrel pin is in the second position.  
     
     
         11 . A lever arm, comprising: 
 an arm including 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 a beam of an exercise rack, such that the arm is configured to pivot with respect to the beam when the arm is coupled to the beam by the mount, the mount comprising: 
 a cuff configured to at least partially surround the beam and to be translated along the beam; 
 a mount handle coupled to the cuff and including a mount handlebar spaced apart from the cuff; and 
 a mandrel assembly including a mandrel bar disposed between the mount handlebar and the cuff and a mandrel pin coupled to the mandrel bar and configured to be inserted through a first hole in the beam, thereby affixing the mount to the beam. 
   
     
     
         12 . The lever arm of  claim 11 , wherein the mount handlebar and the mandrel bar are substantially parallel. 
     
     
         13 . The lever arm of  claim 12 , wherein the mount handlebar and the mandrel bar are configured to be parallel to a longitudinal axis of the beam. 
     
     
         14 . The lever arm of  claim 11 , wherein:  
       the arm is configured to pivot with respect to a first lateral side of a plurality of lateral sides of the beam when the arm is coupled to the beam by the mount; and 
       the mount handle is configured to be disposed on a second lateral side of the plurality of lateral sides.  
     
     
         15 . The lever arm of  claim 14 , wherein the cuff further comprises a cuff crossbar configured to allow a removable pin to be inserted through the cuff and a second hole in the beam, thereby affixing the mount to the beam. 
     
     
         16 . The lever arm of  claim 11 , wherein the cuff defines an inner cavity, and wherein the cuff is configured to receive the beam within the inner cavity.  
     
     
         17 . The lever arm of  claim 11 , wherein the cuff includes a cuff wall configured to allow the mandrel pin to be inserted through a hole in the beam, and wherein the mandrel pin is biased by a spring toward a first position in which the mandrel pin is configured to be inserted through the hole in the beam. 
     
     
         18 . A system, comprising: 
 an exercise rack including a beam; and   a lever arm comprising: 
 an arm including a first end and a second end, the first end including a handle portion configured to be grasped by a user; and 
 a mount rotatably coupled to the second end of the arm and configured to:  
 releasably couple the arm to the beam; and  
 allow the user to unfix the mount from the beam and reaffix the mount to the beam with a single hand of the user. 
   
     
     
         19 . The system of  claim 18 , wherein the mount is further configured to allow the user to translate the mount along the beam with the single hand of the user.  
     
     
         20 . The system of  claim 19 , wherein the mount is further configured to allow the user to unfix the mount from the beam, translate the mount along the beam, and reaffix the mount to the beam using a mount handlebar and wherein the mount handlebar is parallel to the beam.
