Abstract
An apparatus for training a waist portion of a human body is disclosed. In the apparatus, sprockets are installed on a portion on which a trainer sits and on another portion which his hands grasp, a drive chain extends between the sprockets so as to drive the sprockets in mutually opposite directions. Therefore, transmission loss of the pivotal energy between the two portions is reduced. In addition, a brake drum and pair of brake shoes are provided to adjust resistance to the pivotal movements between the portions, therefor adjustment of the resistance can be achieved without electrical power.
