easy exercise - place fingers of left hand on the table at about the same angle they would be on the strings -- lift each finger - one at a time - as high off the table as you can without the other fingers lifting off. you can do this at work, in school (I do not suggest you do it while making love to your girl) Eventually you will be able to add a variation that goes like this -- lift one finger, straighten it, bend back and return to table.
