To protected one, I have a timer, I move , shoot from behind cover, I also do a few wind sprints and push ups to keep the heart rate up. I was at a well known range this summer for a shooting competition, Most of the guys there were geared up to the max, however they were grossly out of condition. I swore I would never get in that shape when I was young, and I kept up on that promise to myself. Your body and conditioning plays an important part in surviving a shoot out, before during and after the incident.
