* Static Flexibility :- It is usually required by a sports person when he remains in static position e.g. Diving, sitting, lying, etc.
* Dynamic Floexibility :- It is needed for walking and running its increase by static stretching.
2. Passive Flexibility :- the ability to do joint movement with a greater range with an external help of partner. This flexibility is largely determined by joint structure, stretch ability of the muscle and ligament. Passive flexibility helps in the development of active flexibility.
