First thing’s first: Eye Dominance
Before learning how to shoot a bow it is important to decide which hand will hold the bow and which will pull the bowstring. As there are right-handed and left-handed people, so there are right-handed and left-handed bows. But what decides if you are a right-handed or left-handed archer? Well the initial answer is your eye dominance. A person who is right eye dominant should hold the bow in their left hand and pull the bowstring with their right hand. The opposite applies for a person who is left eye dominant. The reason behind this is to align the dominant eye over the arrow for aiming.
It can become difficult when a person is right-handed, but with a left eye dominance or vice versa. What hand to use then? I would have that person use a right-handed bow, based on their right hand shoulder being naturally stronger than their left. The only problem then is to control the aiming with the right eye, rather than the left. The person will probably have to keep their left eye shut, until learning to use their right eye for aiming.
