Newton's Law of Motion: "Every action shall have an equal and opposite reaction."

Let's say we're out on a boat in the middle of a lake. The boat is just a small fishing boat, not a huge yacht. We decide we're going to go swimming. I stand up at the edge of the boat and jump off. What happens to the boat? The force from my legs is transferred into the edge of the boat. Since the boat is on a fluid medium (water), the boat is then moved away from its original position (opposite of my motion) by the force of my jump. How is this related to goaltending?

When I watch goalies in camp, I see too much arm movement. For example, goalies who are shuffling often wave their arms every time they push to shuffle. They look like they are making snow angels. Obviously not to that extent, but with a similar motion. That extra movement of the hands away from the body, takes away from the power of the push from the legs. Every action shall have an equal and opposite reaction.

Take a look at Jean-Sebastian Guigere of the Anaheim Mighty Ducks next time he's on television. When he moves side to side, his hands stay in the same position. When he makes a butterfly save, his hands stay in the same position. In all of his movements, his hands stay in the same basic position relative to his body. The reason for all of this is to keep things simple. By keeping things simple, he is able use less motion, and in turn eliminates the number of opportunities to make mistakes.

I've learned that if simplicity is good enough for the 2003 Most Valuable Player of the NHL playoffs, then it's good enough for me as well.
