When the forearm is pronated, the brachioradialis tends to supinate as it flexes. Some have associated a "pull-up" with utilizing an overhand (pronated; palms facing away) grip. Foot cavus increases when the forefoot is pronated. The more pronated foot will have the more forwardly rotated innominate bone. Some have delegated the term pull-up to refer to the pronated (overhanded, palms-away) grip. At the end of step 1, the foot is maximally abducted but never pronated. One is said to be "knock-kneed" if one has overly pronated feet.
