So long as it (RFT), in the way that I always see it used ("Now lift the club up the plane with your r. forearm...") is not the only way. (and not always ONLY with the r. forearm, by itself)
R. forearm lifts in all strokes.
Cool.
That right forearm is very cool indeed .
I've been trying to show here is the role of the right forearm and its participation at startup controls all three dimensions of the onplane golf stroke simultaneously and its influences on the left arm as the power package is transported.
