As much of my handgun shooting is offhand. When watching television, I merely pick out a small object, light switch, coat button on coat tree, ect. , and go through a routine simulating the shot. As my handgun is quite heavy (S&W XVR), I am developing greater muscle strength and better gun/trigger/sight breathing control. Even if shooting from a rest, the trigger control, sight picture, and breathing are all elements to work on! memtb
