something someone had shown me a while ago was to start down around the 12 fret and at first the high e string. place your fingers one fret apart, it will be a challange at first. keeping all your fingers down play the string then lift the pinky and play etc.. then go back. When that gets easier move up a string and when you get to the low e move up the neck to say the 10th and continue. It helps both your reach and finger strength.

Also the previous comment is great as well…

time and practice …. keep at it. you will get it.
