It depends on what kind of boxing you practice or the movements you are used to when hitting boxing targets. For example, the height required for frontal standing and standing posture is different, so many people will compromise so that they can fight in both positions.
Look at a person's height If more than one person calls, try to compromise.
Look at the exercises again, such as adjusting the position and orientation of the boxing target when upping the hook, and some people even put the boxing target flat or inclined when splitting the fist.
