<p>An arm training device (10, 60) comprises a resilient and extensible tether (32), a set of bindings (14) for the upper (24) and lower arm (26), such that the set of bindings (14) is connected to each other and to the tether (32). The other end of the tether is then connected to a restraint means (20, 62) which provides resistance for the arm moving or exerting motion away from restraint means (20, 62). In one embodiment (10), particularly suitable for development of both arms, two sets of arm bindings (14) are provided for attachment to upper and lower parts of both arms and the tethers (32) of each set of arm bindings (14) are then attached to a belt (20) to be worn about the waist. In another embodiment (60), a single set of arm bindings (14) is provided for attachment to upper and lower parts of the one involved arm, and the opposite end of the tether (32) is provided with a loop (62) or similar means for attachment to a stationary source of resistance or to be held by the trainer.</p> |
