Brachioradialis puts the forearm into a midpronated/supinated position from either full pronation or supination. In a supinated position, it tends to pronate as it flexes. Forearm is supinated, with palm towards the body. In slow movements and in the supinated forearm it has a minimal flexor action. The palms should be facing up (supinated). Encircling the radius, supinator brings the hand into the supinated position. This can be done with two hands switching to a supinated catch.
