Fitness can make taciturn people howl their strength from the heart.

Body-building can make the shrew man with blue fingers become burly, and let the majority of girls favor the arm with security.

Fitness can make you full of absolute strength, and use your fists and strength to accomplish things that words can't do, such as playing hooligans.

When those sickly and miserable people are sitting in Internet cafes, playing games, coughing from time to time and massaging sore wrists, you are exercising. Fitness can make a person sunny, and you will meet a group of like-minded friends.
