No, not at all. It triggers the lower body to brace, much the same way Hogan moved. Easy to show in person.

Somewhat similar if you were to imagine throwing a sack of feed into the back of a pickup. Force moves through the body, with the legs being very involved.

Edz,
I would like to put your theory to the test and measure to see if this would occur.
Would be very interesting to see the outcome.
Has anyone measured your theory to verify this works?
Ground reaction forces create hip rotational torque. Normal forces alone won't create hip rotational torque which your speaking about.

Is this your theory Edz and belief or has it been measured and proven it works?
