A military press exercise machine for exercising the arms independently against a selected weight resistance includes a frame symmetric with respect to a midplane, a seat connected to the frame to define a declined exercise position for an exerciser, and a pair of levers with rearward ends pivotally connected to the frame on opposite sides of the midplane, above and behind the exercise position. Hubs located near the forward ends of the levers are adapted to hold weighted plates to resist upward movement of the forward ends of the levers with respect to the pivot connections. Handles located adjacent forward ends of the levers are adapted to be grasped by an exerciser in the exercise position and then raised upwardly in a military press motion against the weight of the plates. During upward movement, the handles move toward the midplane. When the arms are extended, the handles reside above the pivot connections of the levers. At the beginning and at the end of the exercise motion, the handles reside substantially in a single transverse vertical plane which is perpendicular to the midplane. A second set of hubs may be used at the extreme rearward ends of the levers to achieve overall zero weight resistance, or to provide "inverted resistance". This military press exercise machine is safe, effective and the weight resistance is known with certainty.
