Hi Jeff,
No, I mean horizontal force. People don’t keep their own balance or their
own weight, especially if they have been told to “give weight”! They lean back or
sideways or press back against the Leftie’s supporting right hand. That is what is tiring.
That pressure is often much greater than the centrifugal force.
Happy dancing,
John

Hi John,
I think people may be using two different things by "support" here? Julian and
I, along with a few others in this conversation, are using "support" to mean a
horizontal force, providing a counterbalancing force to resist the centrifugal force that
would otherwise send the two people off in opposite directions. I think you're
interpreting "support" to mean a vertical force, which I agree you shouldn't
need to provide.
If you're swinging quickly there really is quite a lot of centrifugal force. Sometime
I'd like to try getting some sort of scale involved to figure out how much!

Hi all,
You should NOT need to support the other person in a Swing. If they are
pulling away, leaning back or leaning sideways then take away your connection until they
take responsibility for their own weight and balance.
The shoulder-blade connection is purely to counteract centrifugal force.
That is not normally a lot of force, so it shouldn’t make you tired. I Swing fast all
night and never get tired arms because, having damaged shoulders, I never let the other
person make me support them.
I completely agree that the Rightie shouldn’t try to reach the Leftie’s
shoulder-blade. See six reasons why at

For good Swing technique please see

Not everyone agrees with everything I say (but I think physics does!). :-)
Happy dancing,
John
