A rowing exercise machine provides a declining, substantially linear path of motion while offering a consistent force angle at the grip. This allows for a fairly consistent torque application at the shoulder joint, throughout the range of motion of the exercise. The exercise machine includes an input assembly which enables a user to maintain biomechanical alignment of the user's wrist and forearm during performance of the exercise, while maintaining a consistent torque applied to the shoulder joint, in the stability of an exercise machine. The input assembly defines a declining, substantially linear path, where the user's forearms remain substantially parallel to the ground as the input assembly is drawn back.
