It may be termed as the ability of an individual to move his body parts to its maximum range around the related joint. It is measured in degrees, radians or centimetres. This is a motor ability which is of great importance for sports performance as well as for leading a normal healthy life. It can be passive or active in nature.
Passive (Left), Active (Right)

1. Passive flexibility: When the movement around the joint is done with external help, then this type of flexibility is termed as passive flexibility. Help may be taken from another person.
2. Active flexibility: When the movement around the joints is done without the external help, then this type of flexibility is termed as active flexibility. Further, active flexibility is sub divided into two parts — static and dynamic flexibility.
Static flexibility

a) Static: When the individual is executing movement around his joints in sitting or standing position, then it is called static flexibility.
b) Dynamic: When the individual is executing movement around his joints while moving, then it is called dynamic flexibility.
