Here are some clips of past Sportsman No. 1 (スポーツマンNo.1). The clips run from the late 90s to about 2001. All of them were taken from the video game Muscle Wars 21. All these scenes need to be unlocked by finishing the game with various characters.
Throughout the clips you'll see Kane Kosugi, Naoki Iketani, Kazuo Matsui, Yoshiaki Fujiwara and several other people.
