i'll tell you what I do. I take a tennis ball and wedge it between my index and middle finger, one between my middle and ring finger, and one between my ring finger and pinky. Then i sit for about ten minutes take them out for ten then put em back in. i do it about 2 times a day, like when I watch tv or whatever, it helps your fingers stretch and then it will get easier to reach. another reason chords may be muted is if you're holding the neck worng. you SHOULD NOT rest then neck between your thumb and index finger. your thumb should be half way down on the neck. when you do it this way, your fingers get much more reach.
