pronated grip

World Records (pronated grip)

Execution: Hold a barbell with your hands shoulder width apart and with a pronated grip (your palms facing your body).

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.

Both recordholders.org and Guinness World Records maintain that pull-ups use a pronated grip, while chin-ups use a supinated grip.

Using a pronated grip during pull-downs tends to result in the greatest activation of the latissimus dorsi, with no difference in latissimus dorsi activity between grip widths.

Pull-ups (including chins) can be done with a supinated, neutral or pronated grip (often called "Chin-ups" "Hammer grip pull-ups" and "Pull-ups" in order).
