Abstract: A personal exercise device with a cable and resistance mechanism comprises a sensor arrangement configured to detect two orthogonal angles to define a trajectory of the cable extending in the 3-dimensional space during use. The sensor arrangement comprises a pulley to direct the cable as it extends from the device during use, a cable follower through which the cable passes, the cable follower pivotally mounted to pivot about a first pivot axis and about a second pivot axis, the second pivot axis orthogonal to the first pivot axis, and wherein the first pivot axis is collinear with a rotational axis of the pulley, and one or more sensors configured to detect pivoting of the cable follower about the first and second pivot axes and provide one or more outputs indicative of the two orthogonal angles to define the trajectory of the cable extending in the 3-dimensional space.
