The weight changes everything
High school boys throw 12 lb, which is 5.44 kg. College and senior men throw 16 lb, or 7.26 kg. Girls and women throw 4 kg, or 8.8 lb, from high school all the way to the Olympic final. A college freshman man usually drops three to five feet in his first season purely from the implement change. Every legal weight, with the body that sets it, is in how much a shot put weighs.
