A compact
high resistance fitness device for superior independent exercising or individual
rehabilitation is disclosed including a platform base plate having at least one pivotally mounted resistance module attached to the platform base plate, where the at least one resistance module has an independent user-selectable resistance setting with incremental
resistance force ranges of from about 5 pounds up to 500 pounds. The resistance module includes a pull cord coil storage spool configured to wrap and unwrap a pull cord of a small
diameter, high-strength pull cord emanating from the resistance module. The high strength pull cord terminates at its outer end by a
handle, such as a hand / foot receptacle, with a length sufficient to allow pull strokes of up to fifty feet or more, with as much weight resistance as a user could want in a compact and portable unit, capable of being taken anywhere for use. Of special interest is that the fitness device may include sensors and other means for collecting data and relaying that data to a smartphone, a computer, the cloud or any other device for display and
processing.
