[Abstract] The present study is related to improvements in a university men's shot-putter's glide. Based on his opinion and video analysis of his motion, it was confirmed that his glide was not contributing enough to the distance thrown. An improved glide training method, utilizing a tilt board, was devised. The present study reports the results for the distance thrown after technical problems with this method were solved, as well as useful information collected during the training. Technical problems included that the shot putter could not lower his center of gravity enough, could not move his center of gravity backward smoothly and quickly, and could not get enough glide speed. During a 16-week training with several targets, his view of the glide changed positively, his glide motion improved, and his performance also improved.
