I don't know that I am training. I do things to keep shooting interesting. I might try something new by moving, varying positions etc. If it isn't new, it usually involves competing against what I've done before or left handed vs. right handed sort of stuff.
That being said, I typically shoot once a week. Our place is large enough that I was able to build a range. Unfortunately, a place large enough to do that requires enough upkeep to keep me from shooting more than once a week. And when I do shoot, I take the time to pick up all the brass.
It's also seasonal. Like in July and August it's too hot and humid to do much outside past the early afternoon - and work comes first so shooting gets cut back.
