An exercise assembly designed to exercise the upper body including the arms, shoulders, upper back and muscles associated therewith. The exercise assembly is thereby particularly, but not exclusively, adapted for use by an injured person or invalid having limited use of the legs and/or lower torso. A track assembly includes two track segments disposed in a convergent configuration and at least partially defining an open end dimensioned to receive a user, when in a seated, substantially upright position, at least partially therebetween. The user accesses two hand grips each linearly and reciprocally along the separate track segments. A resistance assembly includes a line interconnecting the hand grips and an adjustable resistance mechanism engaging the line so as to apply a movement restricting force thereto. An adjustable resistance is thereby applied to the linear, push/pull movement of the hand grips, as applied by the user.
