A tip on here that worked for me was pulling my elbow in tight. This allowed me to get more on the tips of my fingers. Just plowing through the tutorials wasnt working for me either. I found a couple of songs in the tutorial section that have one or two barre chords to practice along with and this made practicing barre chords much more enjoyable. Hotel California (made easy) includes a bonus lesson:verse arpeggiation that is a great exercise for making sure each string is ringing clear on both your barre chords and open chords. I start out with this each practice session
