Shooting is a very individual situation, but for what it's worth here is what Leo suggests at his clinics.....stand in a relaxed, upright position, well balanced on both feet. Use your foot position to help you pivot from the waist, keeping your shoulders level. You should be balanced before you call for the target, remain balanced during the shot and be balanced after the shot. This gives you more control and a relaxed position requires less energy, allowing you to shoot more/longer before fatigue becomes a factor. Seems to work for Leo.....
