Virtually all experienced disc golfers use what is called the x-step. This allows the player to throw the disc with the entire body, rather than just the arm. Different players have their own nuances and tweeks..but the basics remain the same. Some players do just the x-step, others add 1 or more steps before the x-step. Also...as you will see in the video links provided...some players face forward before beginning the step....some are sideways.
Common mistakes: One common mistake is holding the disc out too far away from the body. Keep your arm fairly close to your trunk as you throw. Another mistake is rotating only the shoulders during the x-step..rather than rotating the hips,shoulders,and entire trunk as one unit.
In the links below,notice the male player starts out facing forward, and takes steps before the x-step. The female starts out facing sideways, and only does the x-step.
