Abstract: A mounting system for attachment exercise machine accessories wherein the mounting bracket is a separate piece that can be attached to the exercise machine prior to mounting of the accessory on the mounting bracket. The mounting bracket can be adapted to mount to existing exercise machines, and is easy to attach to an exercise machine separately from accessories to be mounted on it. The mounting bracket facilitates attachment of interchangeable accessories through a simplified mounting system that allows the user to keep both hands on the accessory during mounting. Play in the interface between the mounting bracket and accessory is taken up by a tensioning and locking device.
