You wrote-: "I can concentrate on my right forearm all day long and swing back and forth with the muscles of the right forearm."

You have an amazing capacity to make unsubstantiated claims, any you seem unwilling to prove any explanations. Which forearm muscles are in use during your back-and-forth swing and what are they doing from a functional perspective?

How can you expect anybody to consider your opinions seriously if you are unwilling to provide explanatory details?

Jeff.
