What do Ligaments do?

Some ligaments limit mobility or prevent certain movements altogether. They are elastic and they lengthen when under tension. When this lengthening is not under control, the joint can be dislocated and should be reset as soon as possible.
Athletes, gymnasts, dancers, and martial artists perform Stretching exercises to lengthen their ligaments which are a necessity for all sports and activities so as to make their joints more supple.
