This paper examines benefits of the exer-learning concept HOPSCOTCH for rehabilitation in spa clinics and at home. It describes a specific application to motivate obese patients in spa clinics for exercise. Furthermore results of an empirical study are reported where HOPSCOTCH was implemented in two spa clinics for a period of four weeks. The results of the study have shown that the concept is very convincing, but mainly depends on the content of the application; however the idea of HOPSCOTCH appeared to have a high potential to be used as a therapeutic agent in terms of motivation for exercise.
