I had a hard time with barre chords as well I also have arthritis in my hands I was using acoustic for the fundamentals part I went to a guitar shop and explained my situation They recommended different strings I think they were lighter . I also had the action lowered . Electric is also easier for barre chords. While I did play a lot of the songs in funadamentals I also learned some Bob Dylan songs 2pick rated . Bob Dylan uses Barre chords in his songs great for learning and practicing barre chords Also dont have your finger flat to barre use the edge of your finger slightly roll it . Just practice a simple barre with your first finger and make sure all the strings ring out . You have to find a position that works for you .
