How do you get more muscle m in my arms in the shortest amount of time?

Hi, i am a freshmen in (BLANK) high school. im 6'5 and 180 pounds, i am also 15 years old. The thing is i am very skinny. I hope to train to become a pro wrestler and be on my path to greatness. But my arms are so boney and the same thing for my hands. I need to be the biggest i can possible be in the shortest time possible.
