I find that the most helpfull exercise in keeping my sights on target are the wrist rollers:

When I do the wrist roller I hold my arms straight out at shoulder level to develop the same muscles I use when pointing a pistol.
But anyway - I don't think that oo0juice0oo problem is from muscle weakness. My gut feeling is it's lack of electrolytes - especially Potassium.
