"Because of our success at learning muscle anatomy, the tendency is to think of the function of any muscle as a constant: always the same.  However, since it is ECONCENTRIC and SYNERGISTIC, muscles can (and must) adjust to the movements required during a specific task, as well as the contributions of all the other muscles to that task."

In Part 3 of our Functional Muscle Function series, Dr. Dave Tiberio explains how true muscle function varies according to the task we are performing.
