The most commonly known throw in disc golf is the backhand. It derives its name from tennis because the motion (having the arm cross over in front of the body, then moving outward and releasing with the arm extended before the body) is reminiscent of the tennis stroke. The same holds true for the forehand, or side arm throw.
The ideal grip for the backhand is cupping the disc on the outside, across from the body, and using the thumb on top and fingers underneath, with the index farthest from the ridge. While a straddle stance might work for some disc golfers, the side-straddle or foot forward stance is most suited for the backhand throw. By keeping the feet in proper alignment and aiming toward the target, the disc will generally travel in that direction without much focus, as long as the release point is mastered.
For the windup, bring the disc toward the opposite side of the body from the throwing hand. If you are right handed, then you would curl the disc toward your left side, around the lower end of the rib cage. Turning the shoulders slightly away from the target, as well as your hips, you are now in a position to gain maximum power from this throw.
The release will be at the moment your arm is fully extended and the wrist snaps forward. Mastering the snap of the wrist and the release timing is one of the most crucial aspects of the throw.
