A method of creating rigid cards (32) having an exercise routine (58) thereon for use by a user (26). The rigid cards (32) are prepared utilizing a computer (34) in communication with a database (40). A plurality of exercises (54) are determined and the exercises (54) are input into the computer (34) to define the exercise routine (58) specific to the user (26). A unique identifier (60) specific to the user (26) is input into the computer (34) and linked to the exercise routine (58). The unique identifier (60) and the exercise routine (58) are stored in the database (40) and printed on the rigid card (32). The method further includes modifying the exercise routine (58) and inputting the modified exercise routine into the computer (34) to define an alternative exercise routine (144). The alternative exercise routine (144) is linked to the unique identifier (60) and stored in the database (40). The unique identifier (60) and the alternative exercise routine (144) are printed on a second rigid card (116).
