I posted this in the BJJ section as well... My son (8 years old) trains and competes in wrestling and BJJ. Sometimes he competes in BJJ on one weekend then competes in wrestling the following weekend. One of his friends (13 years old) used to do the same thing but then started confusing the two sports and would do some wrestling moves during BJJ and vice versa so his father now divides his sports into "seasons" such that he only competes in wrestling during wrestling season and no BJJ. When there's a BJJ tourney coming, they dont train in wrestling. Does anyone think I should do the same thing with my son? Is concentrating on one sport at a time the way to go? Here's my take but I'm open to suggestions... Fortunately, my son doesn't have this problem. He DOES combine some moves but in a positive way. He doesn't pull guard during wrestling and doesn't give up his back during BJJ. In BJJ he sometimes opts to half-nelson the person over and other times he takes there back. He even does one quick elbow escape in wrestling which leaves his opponent scratching his head while my son escapes. He also does a quick half-nelson directly into side control during BJJ nad etc... Incidently, he does equally well in both sports. He has numerous tournament titles in both wrestling and BJJ. Here's his 2009 highlight video: Any thoughts?
