A rhythm indicating exercising device in the form of a generally tubular member having a preferably metallic mass or slug disposed freely slidable in the interior of the tubular member, each end of the tubular member being provided with an end closure preventing the mass or slug from escaping from the tubular member. In use, one tubular member is grasped in one hand or, preferably, a pair of tubular members are held one in each hand of a person while walking and more particularly while engaged in aggressive exercise walking, that is while walking at a fast pace with extensive swinging of the arms back and forth. At the end of each forward and backward stroke of the arm, the mass or slug is forcibly propelled by inertia within the tubular member and caused to strike the corresponding end closure, thus producing an impact knocking sound helping the walker to maintain an effective rhythm and providing beneficial advantages in indicating proper exercising of the arms in addition to the legs.
