Always think toe nails to fingernails. I learned this from Wilf Paish, an English coach almost fifty years ago. If in doubt, look for and train connections. Ankle to knee and hip to shoulder, shoulder to elbow, and elbow to wrist, the body is a link system. What you do in one link effects all other links. The link system is designed to reduce and produce force harmoniously in all three planes of motion. Sport movements are coordinated actions in pursuit of specific goals – throwing a ball, propelling through the water, jumping high or far. All are the result of muscle synergies applied to the skill of the sport through directed practice. Get hip to shoulder and you can’t go wrong.
