A dual-mode exercise apparatus may include an articulating arm assembly coupled through a joint to a support assembly. In an illustrative embodiment, the arm assembly may include a seat centrally mounted above a ball-and-socket joint and a stabilizer member for the hands and/or feet of the user. In a first mode of operation a user sits on the seat and uses his or her core muscles to articulate the seat on the ball-and-socket joint against the resistance provided by, for instance, weights mounted on distal portions of the arm assembly. In certain embodiments the apparatus may further provide a second mode of operation which simulates rowing a kayak. In a corresponding illustrative embodiment a user sits in a second seat positioned rearward of the arm assembly and the arm assembly includes handle members. In operation the user articulates the handles in a manner akin to rowing a kayak.
