Frisbees can be thrown in many ways. All involve spinning the disc to give it gyroscopic stability, and accelerating its mass to a certain velocity. Without spin, a disc will wobble and fall; without velocity, the disc will not go anywhere.

At Windsor Ultimate we focus on two techniques to get beginners right into the action:
This is undoubtedly the most commonly learned throw, and also one of the most powerful.
Grip: Fingers are curled under the disc's rim, and the thumb is placed on top of the disc to hold it in place. The index finger may either be on the edge of the disc (to help aim), or four fingers may be tucked underneath the rim (to aid power).
Throw: The thrower draws the throwing arm across the body from the left to the right (for right-handed throwers) to build velocity for the disc. During this movement, the arm straightens out. As the arm becomes straight, the wrist is flicked to impart spin. For backhands, the thrower should step with his strong leg (the same side as his throwing arm) forward or across the body to allow a smooth, accurate throw.
Also known as the flick. Focused in the wrist, this throw takes little time to execute. Along with the backhand, it is one of the two most common throws used in Ultimate, as it allows throws from the opposite side of the body from the backhand.
Grip: The middle finger is extended and laid along the rim of the disc. The index finger is placed against the middle finger for power, or pressed on the bottom of the disc pointing towards the center for stability. The thumb is pressed against the top of the disc. The wrist is cocked back, and the arm is extended out from the body.
Throw: A snap of the wrist imparts spin as the disc releases off the middle finger, as well as some forward velocity. Extension of the lower arm provides additional power, as does shoulder and upper body rotation, although too much reliance on arm movement can lead to "floaty" throws with little spin.
