Flexibility is defined by Gummerson as "the absolute range of movement in a joint or series of joints that
is attainable in a momentary effort with the help of a partner or a
piece of equipment." This definition tells us that flexibility is not
something general but is specific to a particular joint or set of
joints. In other words, it is a myth that some people are innately
flexible throughout their entire body. Being flexible in one particular
area or joint does not necessarily imply being flexible in another.
Being "loose" in the upper body does not mean you will have a "loose"
lower body. Furthermore, according to SynerStretch, flexibility
in a joint is also "specific to the action performed at the joint (the
ability to do front splits doesn"t imply the ability to do side splits
even though both actions occur at the hip)."
