A change of direction machine provides training for various muscles and body structures of a user. In one embodiment, the machine provides focused training for the muscles and body structures associated with making changes in the body's direction. The machine may comprise a pivoting arm assembly supported by a structure. The arm assembly may be configured to provide a resistance such that when a user engages the arm assembly a downward resistance may be applied to the user. The user may engage the arm assembly with his or her upper body and perform training or exercises involving lifting and lowering the user's body, moving laterally, or both. The machine may have various adjustable components to fit a user and to provide the desired resistance to the user.
