Trivia

 * As Nagatoro explained, stretching are divided into two types: dynamic stretching, when you move your body dynamically in order to make your joint more mobile and loosen up muscles, and static stretching, when you slowly stretch your muscles for several seconds to lessen muscle fatigue the next day. The first type is done before exercise, while the second is done afterwards.
