That old F shape is a tricky one. I had to sneak up on it, barred the two high strings only (at first) and focused on getting them to ring out, then added the G and contorted around until those three all rang and then added the D. This allowed me to dial in the pressure I needed to make it ring. I found I was trying to use too much brute force and became aware of the importance of precise placement of the fretting fingers. As you go through the contortion motions don’t forget to consider your elbow and shoulder as points of rotation not just wrist and fingers.
