Weight training machine for exercising the upper chest muscles

An exercise machine for exercising the chest muscles of a user, comprising:

• a frame configured to rest on an underlying surface;
• a seat mounted to the frame;
• a backrest mounted to the frame above the seat, the seat and backrest being configured to receive a seated user;
• a pair of movement arm units pivotally interconnected with the frame and movable about respective generally parallel first and second axes of rotation, each of the movement arm units being configured to engage the crooks of the elbows of the user, each of the pair of movement arm units being movable, within a range of motion plane that is generally normal to the axes of rotation, between an extended position, in which the seated user's upper arms are extended sideways from the shoulders, and a flexed position, in which the user's upper arms are extended forwardly from the shoulders, wherein each movement arm unit includes a swing arm pivotally interconnected with the frame and a rotary arm that is pivotally interconnected with the swing arm;
• wherein the range of motion plane forms an angle of between about 40 and 60 degrees with the backrest;
• and
• a resistance system connected with the movement arm units that provides resistance to rotation of the movement arm units relative to the frame as they move from the extended position to the flexed position.
