After having determined your dominant eye (cf tip sheet why determine your dominant eye)~Are you right handed? If so, then you should hold the bow in your left hand, which is commonly called the bow hand. However, if you are left handed, the bow should be held in your right hand.
This entire first step concerns the bow's handle.
The central part where you will place your hand is called the "grip".
HOW TO POSITION YOUR HAND ON THE HANDLE GRIP?
Start by placing your hand at the handle. Maintain a minimum of support so as not to squeeze it excessively. There should be very little tension on the string so that you can properly position your hand on the bow's handle and therefore balance the power of each limb.
The best way to hold your handle is to grasp the grip with the hollow of you palm so that your palm is pressed against the edge of your grip.
Lightly holding the grip will keep the bow in position.~As you improve, the bow will be supported by your palm, anchored between your thumb and index finger, and held in place by a strap.
