the rum soaked fist: internal martial arts forum

have you heard of this "brain training" and "coordination training"? seems to be stuff like juggling two balls in your hands while standing on a wobble or bosu type of structure then kicking a soccer ball at the same time. visual concentration and new coordination challenges that seem general, not so specific to a sport or art. marketed toward "brain training" and coordination for pro athletes or would-be pro athletes. looks interesting enough and simple enough to try some homegrown recipes. heard of it or similar in ima or ma circles? any experience?
