Wind up and move your upper body and hips - the rest will follow👊🏻

At fisrt, learn how to fakie bs 180 and nollie revert. When you got it, put it together and try to slowly overrotating that 180, put more weight on front foot and pivot it to 360. Then you can try do it higher without reverting, but i think that revert is basic. So I strongly recomend to learn it before trying full 360 .. And its all about your arms, upper body and timing... When you pull stronger, the spin will be faster and you can go higher, but it ll be harder to land.
