Rope skipping is a comparatively simple and easy exercise for people to perform solitarily anywhere. There are four stages for mastering double-under. The first two stages involve training the segmental motion, while the last two enhance the integration of the segmented motion mastered earlier. In the case of plyometrics like rope skipping, a learner may face tough challenges, requiring a fine adjustment of segmented motion at a faster pace and accurately in a short period of time. Therefore, this paper proposes a realignment of stage-organization with an additional step to address this challenge. We develop a supporting system so that learners can comprehend the essence and image of the target motion independently. The evaluation results indicate the effectiveness of our proposal.
