Happy Gilmore, quite possibly the best golfing movie ever, has actually improved my DG game. How? Well, when Chubbs was giving Happy one of his first lessons he made a point to tell Happy that "It's all in the Hips."
In DG the hip-turn is even more important than it is in ball golf. The "X-Step" footwork is the foundation for the proper hip turn and resulting shoulder turn. Most of the power in a throw is generated from the legs which rotates the hips and causes the shoulder rotation. Many players often try to muscle the disc, forcing their bodies to work extra and often endangering their muscles, ligaments and tendins.
During the second part of the X-Step, my left foot will go behind the right leg and will step in front of the right foot. This is when your hips will rotate causing your shoulders to follow leaving your throwing arm extended ready to explode. At this point, I try to focus on my right hip, as much as possible. While keeping my shoulder in line with where I want to release, I rotate my right hip clockwise with a good amount of speed and power. This causes my upper-body to unwind and eventually release a low effort bomb.
Just some thoughts....
