The disclosure provides apparatus and methods of use pertaining to an adaptive, multi-functional exercise device. In one embodiment, the exercise device includes a split carriage formed of separate carriage platforms that may optionally be used in a unified mode, in which the carriage platforms move in unison, or in a split mode, in which the carriages move independently. The device also includes at least one set of ropes that are tied to the carriage platforms such that they translate the resistance of the carriage platforms when manually manipulated. The device further includes split hand and/or foot rests that may be adjusted in multiple directions depending on the demands of the particular exercise in practice. Other embodiments are also disclosed.
