Flexibility And Mobility – What Is The Difference

Do you know the difference between flexibility and mobility? In this short article I will explain what is the difference between the two and in subsequent article on the topic we will look at what are the limiting factors of flexibility, how to improve flexibility and mobility and examples of exercising.


MOBILITY – ability to move or be moved freely and easily. MOBILITY is an indication on how well and efficiently we move.

FLEXIBILITY – quality of bending easily without breaking. FLEXIBILITY is a component of MOBILITY.


MOBILITY – how loose you feel, or how stiff you feel.

FLEXIBILITY – muscles length


MOBILITY – the whole picture, how easily the body can move.

FLEXIBILITY – specific to a particular movement or joint and it can vary around the body.


A person with MOBILITY can perform daily activities or certain exercises with more ease.

A person with FLEXIBILITY may not be able to move as easily. They have the flexibility but not necessary the freedom of movement. Mobility can limit the potential we gain through flexibility.


Physical Therapist, Author and Coach Gray Cook explains that MOBILITY is actually more anatomically and physiologically correct because it encompasses any structure that could restrict motion.

FLEXIBILITY would only imply structures having tension on them. Calling all limited motion problems “flexibility problems” assumes that all can be helped with stretching. Sometimes it cannot.


Bottom line flexibility without mobility will limit our bodies to function and move as they should. In future articles on the topic I will also talk about exercises and how to improve flexibility and mobility
