Claim:
1. An exercise device, comprising: a guide member rotatably arrange on a shaft; a continuous, flexible pulling member which wraps around the guide member and causes the guide member to rotate when the continuous, flexible pulling member is pulled; two rotatable metal discs arranged coaxially with the guide member on the shaft, one rotatable metal disc of the two rotatable metal discs being arranged on each side of the guide member; a gear set operatively connecting the guide member and the two rotatable metal discs; and a magnetic cylinder arranged substantially parallel to the shaft between the two rotatable metal discs such that a magnetic field passes through radially outer areas of the rotatable metal discs in a substantially axial orientation, wherein the rotatable metal discs and the magnetic cylinder form an eddy current brake which counteracts a pulling motion on the continuous, flexible pulling member, and wherein the magnetic cylinder comprises two magnets which are adapted to be moved axially relative to each other by a regulator, thereby causing the eddy current brake to become more or less effective based on an axial position of the magnets within the magnetic cylinder.
