The sport in which athletes compete to see who can hold the heaviest barbells is called weightlifting. To participate in weightlifting, you need a lot of upper-body strength.
In the Olympics, weightlifting is an event in which competitors heft enormous, heavy barbells up over their heads and attempt to hold them there. These barbells are stacked with weighted plates and can be as heavy as 250 pounds. Weightlifting requires powerful arm, back, and shoulder muscles, whether it's done competitively in the Olympics or as part of strength training for other sports.
