Can boys practice jujitsu?

Ronald Sandar, from South America, is 20 years old, but he is the Guinness World Record holder for the men's back-supporting bridge. He is called "Boneless Man". The angle and difficulty of his supporting the bridge even exceeded that of many female contortionists.

However, 1 1 years old is too late. If you need to reach a certain level, you need to work harder.

Good luck!
