Which of the following best describes balanced stretching?
a. stretching many groups of muscles throughout the body
b. targeting a specific muscle group for stretching
c. balancing on one hand or foot during stretching exercises
d. stretching without bouncing

The answer is letter B. 

A type of a balanced stretch involves targeting a specific muscle group. When stretching, a person should be aware of the agonist and antagonist muscles being stretched in able to create a balance between the joints where the muscles are attached. Stretching is an important phase in the exercise cycle and should not be missed as this prevents injuries in the joints and increases the blood flow into the muscles that were used during the activity. Stretching also contributes to lessening the lactic acid build up that happens during physical activity.
