One of the preps I use, and have incorporated for agencies, is a 100 yard dash, pick up a 60 lb. truck tire, run around a small building, grab your rifle, and start the course. It pumps you up, provides a strenuous activity, and gets your heart and mind going, similar to a lot of hunting. Then you work your way down the course with EFFECTIVE shooting. As we all know, misses don't count, but result in fertilized ground!
Practice off a bench is fine for checking your rifle, but is not practice for hunting situations.

If one does not want to practice shooting, then practice running with your shorts full!
