And the interesting thing is on the multiplicity of what it causing the strong man's strength to fail
Is it really
failing? In the purest sense...no! His strength is actually being applied
. That's why he is tired. It's just being applied to a place where it has much less effect
on CXW. There is more than one thing going on to make that work, and actually there is so much more he could do if he wanted to. This is just a power display without too much by way of active jins/aiki.
In more realistic encounters neither
would be so dedicated to a static display with no real goal in mind other than a show. They would look more normal and be more fluid. The real work is having a strong guy who knows how to fluidly apply multiple and rapid changing force vectors in throws (jujutsu/judo) as well as set ups and punches and kicks....and then playing with those. Push hands is a playground for learning that and it leads to the ability to handle fighting stress-but only if you are willing to go down that road and deal with men with fighting skills. Everything else is cool as well. It's just choices and degrees on a theme.
