“Every time I see a boxing bag at the gym, I’m always curious about what’s inside. Is it just simple sand? Or is there something special? This has always been my curiosity and fantasy. Today, I finally fulfilled my fantasy and created a “force feedback” punching bag. It can make the workout less boring and make you love sports more.”
