An exercise assembly structured to perform different rowing routines characterized different rowing motions. A resistance device is movable within a chamber and is cooperatively structured therewith to resist such movement. A drive assembly includes two drive sections each independently connected in driving relation to said resistance device. A connector structure includes two connector members each attached to a handle and connected in driving relation to a different one of said drive sections. The handle is selectively movable through the plurality of different rowing motions, at least one of which results in the two drive sections concurrently driving the resistance member and being concurrently driven by the two connector members. At least one other rowing motion of the handle is defined by each drive section alternately driving the resistance member and being alternately driven by interconnected ones of said connector members.
