Right forearm question

[ChrisNZ]

What is the role of the right arm in the standard left arm swing? Does it have a ‘passive pushing’ role at impact or perhaps a role in increasing effective mass? If not, what is the point of having a right arm for swinging at all (not talking Tomasello here by the way!)

It seems to me the right arm could be passive up to impact and then resist impact deceleration. When the ball is hit the club decelerates. If the right arm has kept up with the pulling left arm, then can’t it contribute to lessening impact deceleration? In effect the right forearm serving as a strut through which the weight of the body gets ‘behind’ the club to resist impact deceleration.

I’m not making myself very clear, but have really been feeling what an aligned right forearm feels like at impact recently (very fantastic!), however I wonder if the feeling I’m having – the support of the right forearm behind the shot which makes me feel like my pivot is pushing from my right side through my forearm through impact - is compatible with swinging – or whether I’m hitting/switting.
