[font=trebuchet ms]The reason they have individual buttons for each finger is to allow you to exercise each finger separately. I challenge anyone who has not tried it before to compress the spring under their pinky without moving the other fingers! It's also very important to do these exercises while your fret hand is held palm up, with the elbow bent, just as you would position your arm while playing. The musles are used differently, depending on how your arm is positioned, so you get it all wrong unless your arm is in the same place it would be if you were actually playing.[/font]
