The apparatus (10) has a base (22) designed for attachment to a fixed vertical support (43). A rotatable arm (14) is held by the base (22) while a braking device provides a variable, adjustable resistance to the arm's rotation. The braking device may be a brake pad (35) and shoe (37) combination, or any other variable resistance mechanism. The arm (14) is held by an arm-support member (21), and a flexible line (13) is attached at its remote end. The arm (14) is designed to rotate in consecutive vertical circles. The flexible line (13) is ideally of a length of about one-half the length of the arm (14) putting its free second end (17) in a convenient position for grasping by hand.
