<p>A wearable exercise pulley comprising: an electrically conducting disc rotatable about an axis of the disc perpendicular to the plane of the disc; a cable coiled around the axis, which when pulled to uncoil the cable from around the axis causes the disc to rotate; at least one magnet that produces a magnetic field, which penetrates the disc and generates eddy currents in the disc when the disc is rotated; and a spring that operates to coil the cable around the axis.</p> |
