Hopefully you've read the first article in this series and gotten your hands on some decent discs.
We're gonna start with putting even though it seems backwards and there are a couple of reasons for this. First, just like regular golf, your short game is by far the most important part of disc golf. If you can putt well, you can post respectable scores. Second, putting is a little simpler and more familiar to beginners who are used to throwing a regular frisbee.
Like I said, putting won't seem completely foreign to you, especially with a putter like the Aviar that I recommended. You'll want to start with your shoulder squared-up to the target and your feet about shoulder-width apart. Your dominant foot should be out in front of your body and you non-dominant foot will be behind your body so that you can rock your weight from your back foot to your front foot as you throw. Hold your putter like a frisbee, with your thumb on top of the disc, your pointer finger extended along the edge and your remaining three fingers supporting the putter from underneath. This grip/stance allows you to hold the disc steady while while using you wrist, arm and body to put some power behind your throw. Try not to let the putter wobble during your throw; don't over-grip, but hold it tight enough to keep it steady.
Think of your body like a spring: you'll "wind up" with your weight back on your non-dominant foot, your arm retracted and your wrist coiled so that you're holding the disc close to your chest. You'll start your throwing motion by shifting your body-weight forward to your front foot. As you start leaning forward you'll extend you arm, flick your wrist out and release the disc with a nice snap. If done correctly, the throw will culminate with your weight completely forward on the ball of your front foot, your arm completely extended so your elbow is straight and your hand open with your palm pointing up. It's going to take practice to get the timing right so all these things happen unison so have patience.
It's very important to keep the disc completely horizontal and steady throughout the throw. If the disc is tilted, it will negatively affect the flight path and make it much more difficult to be accurate with your putts. Don't worry if the disc glides left (if you're right handed) a little bit when you throw; this is perfectly normal and you'll learn to adapt. As you start to see some consistency with your throw, you can adapt to this natural flight path by either adjusting your aim a tad to compensate or by tilting the disc ever-so-slightly opposite from the direction that it is falling. If you're right-hand this mean tilting the putter a tiny bit to the right when you throw.
Don't try to overpower your putts. If you find that you're not close enough to the basket for this style of putting, use the techniques that I describe in my next article. You can still use your putter, only the throw will change; you'll be surprised at how far these putters can fly and they are generally the most accurate discs.
The keys you'll want to focus on the most are a smooth throwing motion, keeping the disc level, and improving your consistency. Putting takes a lot of patience and practice so don't get discouraged if you're sucking it up at first. Remember, this is supposed to be fun.
