A swing training device has an upper cuff for removably receiving an upper arm of a user and a lower cuff for removably receiving a lower arm of the user. A hinge connects the cuffs, which are movable about the hinge and relative to each other between an extended position and a retracted position. An elastic member biases the cuffs toward the extended position. The device may be utilized for medical uses, such as for rehabilitation or strengthening exercises.
