Abstract
Exercise devices which are arranged to replicate the feel and effect of exercising with free weights but providing resistance in two directions away from a null position are disclosed. One example of a device comprises a handle 1021 which can be grasped by an exerciser and which is mounted on an articulated arm portion 1002 which in turn is mounted to a frame 1005. A weight 1031, lever arm 1032 and hydraulic transmission means provide resistance to movement. A first arm member 1022 is pivotally mounted to allow pivotal movement about an axis. Pivotal movement about this axis in two directions away from a null position is resisted by the weight 1031. The weight 1031 also tends to urge the arm member 1022 back towards the null position. The null position can be adjusted using the hydraulic arrangement.
