Rope Jumping

i have the experience of watching a lot of hajime no ippo

first you'll need a fishing boat

This is like a basketball player with leg asking what type of strength training he needs to do to get better at basketball..

Sign up for classes and get hit in the face. If you can handle getting your face smashed in then learn how to box.

Idk that's just me. Honestly have no clue what you're getting at from this.
