2 muscle groups:
Experiment-
Sit in a desk chair - piush away from the desk with palms against edge of desk fingers on top, thumbs inward. pushing tends to roll the elbows out- ccw right cw left.
--push away from the desk but with fingers under edge of desk, thumbs up/out. pushing tends to roll elbows in- cw right , ccw left.

two different muscle sections of tricept used?? have you noticed this and if so - which way do you do Extensor action and why??

HB

Yes, that's almost exactly what I'm talking about. The #1 Accumulator is straightening the Elbow while the Hand moves Straight Away from the Right Shoulder as though it were tracing a straight line from the Right Shoulder.

Extensor Action is the Right Hand moving Away while keeping the Elbow checked.

This, I think is already agreed by many.
