1. An exercise apparatus, comprising:
- a frame;
an exercise station having a seat cushion and a back pad, the back pad pivotally positionable about a first pivot;
a support member carrying the first pivot, the support member pivotally positionable about a second pivot fixed on the frame;
wherein a portion of the back pad proximate to the seat cushion is longitudinally positionable with respect to the frame independent of the seat cushion by adjustment of the support member about the second pivot;
a first locking mechanism to secure the support member at a desired angle with respect to the second pivot;
wherein the back pad is pivotally positionable about the first pivot without releasing the first locking mechanism;
a second locking mechanism, separate from the first locking mechanism, to secure the back pad at a desired angle with respect to the first pivot.

Abstract
An adjustment mechanism for a back support cushion of an exercise machine has two separate pivotal adjustments. One pivot is located above and behind the back support cushion and a second is located below and behind the back support cushion. A two-arm linkage system connects the back support cushion to the exercise machine at the two pivot locations.
