I'm struggling now for a few weeks with the A shape barre chord on the 5th string. Somehow my ringfinger doesn't want to bend backwards in the required way for a 'double bar'. I really try to pressure in downward around the knucle, but it seams unbending.The alternative, using three fingers instead, doesnt really appeal to me. I found that one difficult to change with and further up the neck too cramped within one spot.
Any tips/ exercises for getting this ringfinger to bend more easily? So far I tried pressuring it to bend backwards with my other hand, but that mostly only hurts.. I can't even seem to hold down two strings with the ringfinger at this point, let alone three...
Thanks in advance
