Learning how to shoot an authentic Mongolian bow is not a complicated thing to do. The biggest lesson you should take away from learning how to shoot Mongolian bow is that it really is all about the placement of your targets, and where you stand on the archery range. The most important part of archery is making sure that you stand up straight and areas pointing in a straight line as possible when you fire off your bow. You also need to keep your back straight because your aim for the bow should be a straight line between your front foot and your back leg.
The second most important part of learning how to shoot a Mongolian bow is what type of drawing you will use to pull back your string. A lot of people choose to use a figure eight to draw their string because it seems more natural to them, but it does not work nearly as well as the pull of a two-pronged draw or even a three-prong draw. Two and three-prong draws are harder to learn how to shoot Mongolian bow with, especially when it comes to drawing the string. I have never seen anybody successfully draw a two-pronged draw with just one hand, so if you want to learn how to shoot Mongolian bow properly you should stick with two or three-prong draws.
Finally, after you learn how to shoot you should learn how to hold your bow. The traditional method of holding a bow is to place your fingertips underneath the grip of the bow, and you wrap your arm around the bow with the palm of your hand facing upwards. However, if you wish to change how you hold your bow there are a couple of different options that you have. If you are going to shoot standard Mongols you will likely do a traditional two-handed hold. However, if you are going to use a compound Mongolian bow you can use either a one-handed or a two-handed hold, but make sure that your fingertips are placed on the trigger. Make sure that the back of your hand is up as well, this allows you to take a relaxed grip of the bow.
