Explanation:
Ballistic stretching is similar to dynamic stretching in that it's movement-based. Instead of moving a body part to the end of its range of motion, however, you attempt to go beyond this range. These stretches often require uncontrolled movements that may result in injury.
ture facts bout it:
Ballistic stretching uses the momentum of a moving body or a limb in an attempt to force it beyond its normal range of motion. This is stretching, or "warming up", by bouncing into (or out of) a stretched position, using the stretched muscles as a spring which pulls you out of the stretched position.
What is the benefits of ballistic stretching?
Ballistic stretching helps to improve flexibility by pushing muscles through a wide range of motions. A pre-workout ballistic stretching session trains the muscles for high impact activity. Hence for physically intensive activities, a quick warm up of ballistic stretches is highly beneficial
