A multi-function exercise machine which makes use of the body weight of an exerciser and has a base frame and a user support frame pivotably mounted thereon. A lever arm mechanism for pivotably raising and lowering the user support frame against the user's weight is provided and comprises a handle bar having a lever arm depending therefrom and carrying a roller on the lower end thereof. An arcuate track is adjustably mounted to the base frame so as to provide an adjustable arcuate pathway for the lever arm roller to travel upon as the user pivotably motivates the handle bars and lever arm secured thereto in order to raise and lower the user support frame. Pushing and pulling exercises may be performed according to the selected position of the arcuate track.
