barbell curl 

(v.) weightlifting manoeuvre in which the lifter holds a barbell flat against his waist whilst standing with forearms turned out. He then rolls the barbell up with his elbows as a fulcrum to just below his chin, before bringing it down in a controlled descend.

The barbell curl is what many people are shown doing in movies.
