ABSTRACT:
A torso exercise machine includes a frame designed to rest upon a floor surface; a seat pivotally mounted on the frame; at least one handlebar pivotally mounted on the frame; and a link pivotally interconnected between the seat and the handlebar. The link constrains the seat and the handlebar to pivot in opposite directions relative to the frame. A resistance device may be interconnected between the handlebar and the frame to resist pivoting of the handlebar and the seat toward one another.
