Keys to a good slapshot come from your mechanics and technique. Tiger Woods is a skinny guy, but can hit a golf ball 400 yards. The same thing goes in a slap shot - it's all about driving your hips and shifting your weight. So no matter what size you are, if you can master the fundamentals of a good slap shot, then you will be a nightmare for opposing goalies!
Slap Shot- Process
Position the puck four to six inches behind your front foot. Make sure the puck is far enough from your body so you have room to comfortably hit it.
When you wind up the stick, always keep your right arm straight (or your left arm if you are left handed). Your weight should be on your back leg.
As you drive your stick to hit the puck, lean into the shot driving your hips and shifting your weight onto your opposite leg.
Swing hard and quick and your stick should strike the ice, an inch or two inches before the puck. This will give the puck some lift when you hit it.
Strike the puck in the middle of your blade. Like hit a baseball, this is the "sweet spot".
Make sure to follow through and roll your wrists over after you hit the puck.
On the follow through, make sure you are pointing at the target and resume a balanced position with your weight fully transferred on your front leg.
