This is usually achieved most easily with vertical forearms that are close to the body. For most, bringing the chin this high is most easily achieved with a supinated (underhanded, palms-toward) grip. Due to this, the phrase "chin-up" has become associated with pulling with this type of grip. Some have delegated the term pull-up to refer to the pronated (overhanded, palms-away) grip. In spite of this, many refer to pull-ups with a pronated grip also as chin-ups, and the supine grip is still regularly called a pull-up.
