What workout are you doing these days?
What are you doing to make sure you are physically fit and have endurance.
What are you doing so you can move explosively? So you can run from trouble and have it stumble after you in a vain hope of catching you?
What are you doing so you can hit someone hard enough that they believe they have been shot?
What are you doing so you are fit and healthy in the event you are shot, because healthy people tolerate injury better than unhealthy people?
