The correct option is B) Each muscle must be stretched individually to improve flexibility
Explanation:
Specificity can be described as a kind of athlete training in which each muscle is focused so that there is an increase in the flexibility of every muscle. It's an excellent technique for athletes who use many muscles for their actions. Your muscles tend to develop a memory of the actions so that they perform their function even when you are not conscious. Specificity brings about the best master skills that are required in an athlete.
