The present disclosure provides a method and device for exercise comprising having two bases each supporting a pivoting arm with a grip attached thereto with a rotating hub attached to each pivoting arm (wherein each hub has a magnetically attractive region thereon and each pivoting arm is movable around 360 degrees). Placing a movable magnetic device in close proximity to each hub (wherein moving the magnetic device will vary the magnetic field being applied to the hub), placing a user grasping the grips (between the bases) and moving the grips around a guided circular pathway and varying the magnetic field being applied to each hub, thereby adjusting the resistance being exercised with, during movement of the grip around one revolution.
