A user impact device, for receiving force from the user may be connected to the two-piece pivoted linkage assembly. The respective lengths of the two pieces of the linkage

An exercise device having a pivoted resistance and a two-piece pivoted linkage assembly to connect the resistance with the user. A user impact device, for receiving force from the user may be connected to the two-piece pivoted linkage assembly. The respective lengths of the two pieces of the linkage assemble and the points of pivotal mounting are used to determine the resistance profile.
