An exercise device having a coupling assembly attaching a pair of symmetrical, elongated arms mounted at right angles to each other. A pair of elongated handles, each one of which is mounted on one of the elongated arms, is provided for reversible rotation thereabout. Each of the handles has a tubular housing which includes a distal wall and a side wall, the distal wall having a coaxially disposed opening formed therein, the side wall having a pair of opposite longitudinal grooves formed on the inside thereof. Three openings are formed in the side wall. A tubular socket member, adapted for rotation about a coupling assembly conical member includes a plurality of keys mounted longitudinally on its exterior wall, for registration with the tubular housing longitudinal grooves to enable cooperative rotational movement of the socket member. The tubular housing locking nubs protruding from the wall of the socket member frictionally engage the tubular housing side wall openings to prevent inadvertent disassembly of the device. An anti-rotation disc is fixed to an anti-rotation boss, the disc being received within the socket member distal end body portion. An elongated nut, disposed coaxially within the tubular housing, enables adjustment of handle rotation resistance. The nut includes a flange which has a diameter greater than the opening in the tubular housing distal wall. A finger engagable blade extends through the distal wall opening to enable adjustability. Spring means coaxially disposed between the elongated nut and the anti-rotation disc provide adjustable resistance to rotation. A frustoconical bushing is disposed between the conical member and the socket member cone shaped recess for frictional movement therebetween.
