Abstract: An exercise device is described. In an implementation, the exercise device includes a frame, a cranking assembly mounted to the frame and an extended user fixture. A user utilizes the extended user fixture to perform exercises.

Abstract: An exercise system and method is utilized with a foot pedal of a stationary bicycle to exercise various body parts including the user's legs, arms, chest, shoulders, back, and abdomen for a complete body workout. The exercise system preferably includes an adapter and a plurality of user interfaces. The adapter is configured to releasably couple one of the foot pedals of the stationary bicycle and one of the plurality of user interfaces. A foot holder serves as one of the plurality of user interfaces. Preferably, the foot holder securely and releasably retains the user's foot. While in use, the user's foot is axially aligned with an axle of the foot pedal and is capable of supplying force to the foot pedal on both the down-stroke and up-stroke portions of the foot pedal's rotation. An external attachment also serves as one of the plurality of user interfaces. The external attachment is preferably designed to transmit force from the user's legs, arms, feet, or hands to the foot pedal of the stationary bicycle.

Abstract: A U-lock includes a detachable header with extensions that fit around the arms of the U-bar and extend along the length of those arms to provide strength to the U-lock. The header can be used so that its base is locked at the end of the arms of the U-shaped bar or it can be inverted when locking smaller objects so that its base is locked along the lengths of the arms taking up some of the gap between the locked object and the base of the header. The header is locked to the arms of the U-shaped bar by a locking mechanism which secures the header to the arms of the U-shaped bar in four different places, two on each arm. The U-lock and header with extensions can also be used in combination with security spacers for further security.
