1. An adjunct training device, comprising:
a main frame configured to detachably mount on to a rowing machine having a seat, a left foot pedal, and a right foot pedal;
a fulcrum attached to a backside of the main frame;
a main lever that is centrally and pivotally connected to the fulcrum;
a laterally-disposed left-side actuator, including:
a proximate end configured to receive a user's left-sided force applied by the user sitting on the seat to the left foot pedal, and
a distal end attached to a left end of the main lever; and
a laterally-disposed right-side actuator, including:
a proximate end configured to receive a user's right-sided force applied by the user sitting on the seat to the right pedal, and
a distal end attached to a right end of the main lever,
wherein the main lever is configured to pivot on the fulcrum in response to unequal application of the user's left-sided force on the left side actuator and the user's right-sided force on the right side actuator, the pivoting of the main lever longitudinally moving each of the left-side actuator and the right-side actuator relative to the main frame, the longitudinal moving of the left-side actuator and the right-side actuator configured to facilitate an equal application of force from the user on the left side actuator and the right side actuator.
