Power moves - back spin

Back spin is the basic power move. If you want to learn any power moves especially windmill, you should learn backspin first. Don`t go straight ahead to your windmill. It will take you twice as much time to learn windmill if you don`t learn back spin first, trust me, i`ve been there, done that.
Back spin is simply spinning on your back, but it takes s lot of practice to make a good back spin. If you want me to make a video guide for backspin. Please tell me. Even though i am just 13 i promise that i will make a better tutorial than many youtube videos that i have seen. Please let me know if you want a good backspin tutorial.
