Music Boxing - Many people want to lose their weight, but it is not easy. Boxing is the good sports to lose weight. I saw many people give up doing boxing due to hardness of boxing. I want to suggest new way to enjoy doing boxing. When you speared each speaker and put your mp3 player on Music Bixing, the notes of song will pop up on the air. When the boxer hit the note like hologram, the song was played by boxer's punch.
