An exercise apparatus has a frame supporting a pivotable lower right arm and a lower left arm, and also a pivotable upper right arm and upper left arm. The upper right arm and the upper left arm are pivotably connected to the frame at points above the pivotable connections of the lower right arm and the lower left arm. The lower arms have handles for grasping by a user and weight pegs. The upper right arm and the upper left arm each further have a rail connected to the arm and running substantially parallel to it. A sleeve slideably engages the rail and supports a shoulder harness for a user and also weight pegs. The user grasps the handles connected to the lower arms and lifts upward, whereby his shoulders contact the resistance of the upper arms through the shoulder harness.
