When you are using a cross wrench, handle the cross wrench upper portion with your inner arm (arm that is near the vehicle) then put your inner foot on the lower portion of cross wrench, then as you pull the upper portion of the cross wrench towards you, push the lower portion of the wrench away from you at same time as shown in the illustration below.
