Claim 36:
37. A method for using a weight training auxiliary device for adjusting a weight training load of training equipment, the weight training auxiliary device comprising:
a plurality of weights to generate a load; and
a weight attaching/detaching mechanism for attaching and detaching the plurality of weights, wherein
at least one of the plurality of weights has an electromagnet or a permanent electromagnet built in
the weight attaching/detaching mechanism includes a conduction relay configured to control supply of power to the electromagnet or the permanent electromagnet of the at least one of the plurality of weights,
the method comprising:
performing weight training by adjusting the weight training load by attaching and detaching the at least one of the plurality of weights by controlling the supply of power to the electromagnet or the permanent electromagnet of the at least one of the plurality of weights, wherein
the conduction relay is arranged on a collar connected to a shaft of a weight machine or free weight equipment as the training equipment to which the weight training auxiliary device is coupled so that the plurality of weights are configured to be set by attaching and detaching the at least one of the plurality of weights with the electromagnet or the permanent electromagnet by powering on or off the conduction relay.
