Golf Movement

Golf is such a peculiar sport, it complains when there is too much movement, it complains when there is too little movement. Starting from the ankle, knee, hip, waist, upper torso, shoulder, arm, elbow, wrist, there is not a single piece that connect the grip of the golf club to the ground that can be neglected or ignored.

If I could invent something beneficial to golfers, I should invent some devices that lock portion of these "hinges" to appropriate degree of freedom. Too much knee movement may cause an overswing, too much hip movement may introduce a hook or slice, too much wrist movement may affect accuracy, too little shoulder turn may lead to a fat shot, too little weight-shift may sacrifice distance... These devices could be as simple as two boards or planks that bandaged together and lock these "hinges" and prevent unnecessary movement except the desire directions.

I have not seen any of these products in the overwhelming golfing-aids market yet. Either these devices are simply not designable or no golfer willing to robotize oneself. I guess I would like to be a robot when I play golf, after all, isn't that every golfer pray and ask for accuracy, distance and consistency?
