ABSTRACT:
This invention relates to a multi-purpose exerciser and in particular to one utilizing a throttling valve for presenting a selectable number of operable speeds to the user. The exerciser mainly includes two racks, a controlling button, a cross rod, an upright stand, a base, two contractible rods, two frames and a supporting rod stand, whereby it can be used to exercise rowing, climbing, skating etc. The force required to operate the pedals of the exerciser is established by the throttling valve which controls the rate of oil passing through a pair of rubber tubes into cylinders housing pistons driven by the pedals.
