An apparatus is disclosed for exercising the arm muscles and upper torso muscles of a user. The apparatus includes a frame and a weighted arm is pivotally connected to the frame with the weighted arm being positioned such that the user is able to lift with the user's arms the weighted arm. A user operated release selectively changes the weight of the weighted arm such that in use of the apparatus when the user has repeatedly lifted the weighted arm a predetermined number of times, the user operates the release to change the weight to be lifted so that the optimum stress is applied to the muscles being exercised.
