<p>The fitness equipment comprises two eccentrically placed deflection rollers, on which one is adjustable, such that a rope running on the deflection roller or a chain is deflected around a right angle and produces a summation of the eccentric movement or a neutralization of the eccentric movement by adjustment of the eccentric roller. The summation or neutralization is attained by two eccentric rollers, which are rotatably fixed on a frame and are rotated at forty-five degrees.</p> |
