4) The following is a visual of the dumbbell fly exercise, which is to build the pectoralis muscles of the chest. Below that is a visual of reverse dumbbell curls, which build the biceps complex with added emphasis on the brachioradialis muscle. Draw the moment vector due to the force of both dumbbell weights for each exercise (LEFT PANEL). Next, draw the moment vector due to the force of the muscles that are applied in each exercise. a.
