An alternate exercise adapter for exercise machines having an intended function is designed to be attached to an exercise machine in order to provide the option of performing alternative exercises beyond the intended function(s) of the exercise machine, thereby transforming the exercise machine (such as a rowing machine) into a multi-use, multi-purpose training device. The adapter may include a pulley mounted on a pivoting arm, affixed to mounting blocks for attaching the adapter to an exercise machine. By placing the exercise machine's drive chain or belt in the open-block pulley, the drive path may be altered, e.g. allowing the transfer of force in the vertical plane. This may allow a user to perform additional exercise movements (bicep curls, reverse bicep curls, shoulder front raises, high pulls, overhead presses, front squats, et. cetera), providing for alternate use of the exercise machine's resistance mechanisms.
