The aim of this paper was to perform "individualized resistance training" with a haptic-based resistance training machine (HRTM) and to compare its effectiveness with conventional resistance training. Five young males performed an "individualized shoulder abduction exercise"; another five young men performed a general shoulder abduction exercise with a dumbbell for two days per week over eight weeks. For assessment of both trainings, we measured average power through isokinetic strength and observed total work done during the trainings. The results of this study showed that the mean value (SD) in the average-power progress was 21.8% (${pm}20.8$) for the dumbbell group and 19.9% (${pm}19.3$) for the machine group; furthermore, the upward trend in the total work-done was approximately 42% higher in the machine group than in the dumbbell group. The result of this study showed that the haptic-based resistance training machine will offer a new and interesting arena for the application of training methods. Additionally, there will be many opportunities for applying the proposed system in the sports science and rehabilitation fields as well.
