I've read that when kids are young their nervous systems are somewhat "plastic"; that is, they have the capacity to greatly improve balance, coordination, agility, speed, etc... I'd love to hear any thoughts on off court training for kids under 12 or so. Are there any specific drills you've employed? Do you think kids who undergo specific training in this regard (in moderate amounts) have a distinct advantage over kids who just play other sports? I know TCF uses the Bosu, Bongo Board, Balance board, but I've also read that improving balance on unstable surfaces doesn't necessarily carry over to stable environments (it recruits the wrong muscles). TCF have you heard about this?
