What can lead to low left arrows for a right-handed archer?

Low left arrows for a right-handed archer can occur due to the string hitting the chest during the release phase of the shot. This phenomenon often causes the arrow to be deflected downward and to the left, leading to a consistent impact point in that area. When a right-handed archer's bowstring makes contact with the chest, it disrupts the stability of the shot, resulting in a lower and potentially leftward trajectory. Proper form and technique are crucial to avoid this issue, and ensuring adequate clearance between the string and the body during the shot can help achieve straighter and more accurate arrow flight.

In contrast, canting the bow to the right would affect the angle of the shot rather than primarily causing low left impacts. Peeking at the target can lead to inconsistent releases but doesn't typically cause the arrows to strike low and left. A weak bow arm might result in reduced stability or control during the shot but would not specifically cause a low left arrow flight as consistently as string contact with the chest does.
