Please correct me if I’m wrong (and I often am) but I think I heard you say one time that you have your volleyball players and throwers throw with their non-dominant hand. Why is this? Perhaps I heard this somewhere else, Not Sure.

Throwing with non-dominant arm has nothing to do with symmetry, I do that for the cross transfer effect, essentially improve coordination.

Is there a difference between physical (aesthetic) symmetry and movement symetry? Instead of movement symmetry a better way of stating it may be biomotor symmetry?

Cyclic movements like sprinting appear symmetrical but with biomechanical analysis we have learned that there are subtle differences right to left. Aesthetic symmetry, what the naked eye can see is good for me.
