It has been said that in disc golf, like ball golf...that you "drive for show and putt for dough". Putting is very important and can make a huge impact in your score out on the course! There are various stances and techniques that can be used. As you progress in your game, you will want to become familiar with them all. For our purposes here....we will concentrate on the basics.
Two of the most common techniques you will hear mentioned are the push- putt and the spin-putt. The basic difference is that in the push-putt, the elbow and wrist remain straight...and the disc is launched forward by using the legs/ hips and "reaching" towards the basket as the disc "springs" out of the hand. In the spin-putt....the wrist and elbow are bent(cocked)..and the player spins the disc towards the basket. This is an over-simplification..but you get the idea.
Bottom line: Don't get caught up in the semantics and finer details at this point. The fact is many players, even some professionals...in actuality use a sort of hybrid technique that they have tweeked to their liking. With time and practice you will settle on a style that suits you. For starters...see the short video demonstrating a basic putt.
