"Koji Matsumoto / Boxing Complete Instruction: Southpaw Edition Part 1" Koji Matsumoto Price: ¥5600 "Koji Matsumoto / Boxing Complete Instruction: Southpaw Edition Part 2" Koji Matsumoto Price: ¥5600 #KojiMatsumoto #CD・DVD This is a boxing instructional DVD by Koji Matsumoto, a famous trainer from Ohashi Gym! He trained Katsushige Kawashima and Akira Yaegashi to become world champions, and he also received the Eddie Award. His son is also an active Japanese champion. I'm a southpaw myself, so this was very helpful for me! It's easy to understand, with explanations divided into offense and defense. I watched it repeatedly until I was tired of it, but the disc surface is clean with no scratches. This is a two-volume set, Part 1 and Part 2. I've memorized the content, so I'm selling it!
