However, such machines lack the broad range of motion necessary to accommodate a user for use with a variety of unrelated exercises used to work various portions of a user's body. What is needed, therefore, is a machine capable of eliminating the need for a spotter while, at the same time, allowing for a broad range of motion for various exercises using a single exercise device.
- The above and other needs are met by an exercise device machine that allows for a broad range of motion using a plurality of exercise techniques. In a preferred embodiment, the exercise device is configured for use with free weights or selectively engagable plate weight stacks for various arm exercises.

During exercise a user urges the slide member along the first guide member, with the stabilizing structure inhibiting pivotal movement of the slide member relative to the first guide member and the connection between the lower pivot member and the base permitting pivotal movement of the first guide member and the second guide member relative to the base.
- In a preferred embodiment, the exercise device includes a base member, an elongate first guide member (including a first guide member base end connected to a lower pivot member, wherein the pivot member is pivotally connected to the base), a slide member movable along the first guide member, an attachment structure connected to the slide member, an elongate second guide member, a stabilizing member movable along the second guide member and connected to the slide member for inhibiting pivotal movement of the slide member relative to the first guide member, an elongate first weight rail including a first weight rail base end connected to the lower pivot member, an elongate second weight rail including a second weight rail base end connected to the lower pivot member, a resistance interaction structure including a weight carriage movable along the first weight rail and the second weight rails for providing resistance to the movement of the slide member along the first guide member, and a pulley system selectively connectable to the slide member and the weight carriage. The slide member is selectively engagable with the weight carriage by the use of a removable engagement member.
