like I was saying, in a bent fh, the arm muscle has to work, but to merely maintain the structure.
not quite and not everybody. depending on your swing mechanics you can swing w/o using arm muscle contraction to maintain the structure. Also a lot of players let the elbow extend during the swing (not to the point of a straight arm). And also depending on swing type you can also maintain the structure using the shoulder muscles only.
Nobody thinks about 'using muscles to maintain the structure' anyway. If they do they are arming the ball and have low rhs.
