1. An adjustment apparatus for adjusting the position of a member on an exercise machine, comprising:

  • an inner tube having a series of spaced, in line, pinning holes;

    an outer tube telescopically engaged over the inner tube and having a locator hole for alignment with a selected pinning hole;

    a lever having first and second ends, a first, pinning section extending from the first end along part of the lever and a second, hand engaging section extending from the pinning section to the second end at an angle to the pinning section;

    the pinning section being pivotally mounted on the outer tube to extend across the locator hole, the pinning section having a pinning button projecting towards the locator hole, and being pivotable between an operative position in which the pinning button projects through the locator hole and an aligned pinning hole in the inner tube to secure the tubes together, and a retracted position in which the pinning button is spaced away from the locator hole;

    a biasing device on the outer tube biasing the lever towards the operative position;

    the hand engaging section projecting at an obtuse angle to the pinning section of the lever and outwardly to one side of the lever, whereby pressing of said hand engaging section in a release direction by a user moves said pinning button from said operative position to said released position; and

    the inner and outer tubes having a longitudinal axis along which the outer tube is movable in order to adjust the position of a part attached to the outer tube, the pinning section extending across the outer tube in a direction transverse to the longitudinal axis of the telescopically engaged tubes, and the hand engaging section having at least an end portion extending generally alongside the outer tube in a direction substantially parallel to the longitudinal axis.
