A rowing type exercise device which is conveniently usable by an exerciser seated in a wheelchair, or other chair-like structure, includes an elongated base structure having a floor supported use orientation in which its rear end extends rearwardly beneath the wheelchair. A force input lever is pivotally secured to a longitudinally intermediate portion of the base structure, and the outer end of the lever is provided with handgrips which may be grasped by the chair-seated exerciser to pivot the lever forwardly and rearwardly in a rowing motion which is resisted, in both directions, by an elongated piston and cylinder unit interconnected at its opposite ends to the lever and a front end of the device. The piston and cylinder unit connection location on the lever may be adjusted to selectively vary the lever resistance force. During use of the device, the user's feet are comfortably supported on longitudinally adjustable foot rest members connected to the base structure forwardly of the lever. A counterweight member is secured to a rear portion of the base structure to inhibit forward and upward tipping thereof during forward rowing motion of the lever. A pair of support wheels are secured to the front end of the device and engage the floor when a carrying handle on the rear end of the device is lifted, thereby conveniently permitting the device to be easily rolled to and from a storage location.
