Abstract: The present disclosure relates to a resistance training exercise device that includes a frame; a holder coupled to the frame, the holder defining a lever channel for receiving a forearm of a user; the holder and the frame configured to rotate with the forearm about an elbow relative to an upper arm when the user is performing a rotary resistance training exercise; and a weight support for receiving one or more weights thereon, the weight support fixed to the frame and spaced apart from the holder in a direction selected to maintain, throughout the resistance exercise, an angle between the upper arm and the weight support that is greater by a constant value than an angle between the upper arm and the lever channel.
