Abstract: An arm training device comprises a resilient and extensible tether, a set of bindings for the upper and lower arm, such that the set of bindings is connected to each other and to a tether. The other end of the tether is then connected to a restraint means which provides resistance for the arm moving or exerting motion away from restraint means. In one embodiment, particularly suitable for development of both arms, two sets of arm bindings are provided for attachment to upper and lower parts of both arms and the tethers of each set of arm bindings are then attached to a belt to be worn about the waist. In another embodiment, a single set of arm bindings is provided for attachment to upper and lower parts of the one involved arm, and the opposite end of the tether is provided with a loop or similar means for attachment to a stationary source of resistance or to be held by the trainer.
