How to Work on Swing Path Without Track Man or Launch Motto

How do you work on your swing path without access to track man or any other launch motto that would measure swing path? You can look at patterns. So, if you are a push player, if your straightest shots are pushes and you hook and your good shots are draws, then you're an into outswinger of the club. If your shots are more pull, slice, and fade patterns, you're an out to in player. The other way to look at it is to hit shots until you hit one on the target and look which way it curved to get there.
