You need an " all of the above" option.

sitting, standing, kneeling and elevated. But standing/elevated 70% of the time I bet.

I voted for standing because thats what I do most of the time but I do thow in the rest expecially leading up to the fall.

Those that continue to do, what they have always done, will always get, what they always got. Practice does not make perfect, Perfect practice, makes perfect!

Standing, kneeling, elevated, body contorted, mask on mask off, gloves, clothes..I try and play out all the possible scenerios.

any way i can think of that might help

I voted standing because I do that the most. I practice any way that I can.
I am about to set up an indoor range in my apt. Just grabbed my target from the cottage on the weekend and figure I can at least keep my muscles conditioned, even if the 12 yd shot isn't too challenging.
