My twins have been taking Jiu jitsu since they were 4. Today one of them took a 3 hour grueling black belt test that had me chewing on my nails and cheering at the top of my lungs. It included between 350 - 400 moves, japanese names and meanings for them, a hundred push ups on his fingter tips, fists, and other torturous positions, balancing moves, sparring against 2 big guys at once, and nunchuck and hanbo routines. Did I mention he only had one 5 minute break the whole time? He made me promise not to yell Woohoo like I always do, so I told some our friends who came to do it for me! The poor kid is sooo soar, black and blue and exhausted but he knows, that if he did this at such a young age he can do anything. He is the youngest black belt in the dojo and his twin is due to take the test in May. I will need that long to get my blood pressure back to normal.
