This training has two different types. Firstly active stretching,
which is performed independently where the performer applies internal force to
stretch and lengthen the muscle. The second is passive stretching, also known
as assisted stretching, which requires the help of another person or an object
such as a wall. The other person/object applies external force causing the
muscle to stretch.

this is where the performer makes fast, jerky movements through the
complete range of motion, usually in the form of bobbing or bouncing. Ballistic
stretching is specific to the movement pattern of the sport/activity to be
performed. It needs to be undertaken with care as the technique can cause
muscle soreness and strains.

This is used to
develop mobility, strength and flexibility. The technique may be performed
with the help of a partner or alternatively by using an immovable object (as
resistance to inhibit movement).
