Claim 31:
32. A weight training auxiliary device comprising:
a plurality of weights for generating a load;
an emergency weight releasing mechanism comprising an electromagnet or a permanent electromagnet configured to release a portion of the plurality of weights in an emergency based on an instruction from a trainee or a signal from a mechanism that detects a trainee state when the trainee is in a danger state due to an excessive load,
the mechanism that detects the trainee state comprising:
a microphone configured to be installed near a neck, jaw or lips of the trainee, and
a speech recognition device that judges emergencies from sounds gathered by the microphone, wherein

the emergency weight releasing mechanism is activated by disabling a magnetic force holding the portion of the plurality of weights by detection of vocalization of the trainee, or by sensing changes in breathing sounds,
when the speech recognition device judges there to be an emergency, the signal is sent to the emergency weight releasing mechanism, and
the speech recognition device uses a sound pressure/sound pitch sensor or a microcomputer.
