Normally we would use plastic molded 3D torso targets but from a legal point of view it won't be possible to use all over the world. So for our classes we devised a proprietary paper target which you can see here.
It has two circles and a vertical line thus it is perfect to practice 3 target zones for point shooting method: belly, larynx and central line. It helps to focus on choosen zone and allows shooter to practice any and almost all basic shooting techniques.
