Instructions. Holding the shot is key. You should rest the shot at the top of your palm, gently on your finger and supporting it with your thumb. The purpose of placing it on your fingers is to receive an extra spring when you put the shot.You then want to push the shot against your neck, under the ear and near the chin.Your arm should be perpendicular to the ground, do not dip it because you do not want to throw the shot like a baseball. Doing so will shred your shoulder. Then get into your power position..ou then want to push the shot against your neck, under the ear and near the chin.
