How can i stop opening up my air position while still in the air???
Just hold it in there tight! If you keep letting yourself pop out of the position, it’ll become a habit. You have to force yourself to stay there! If you’re popping because of fear, well- first of all, my coach tells me that staying in that tight position is so much safer than popping! You might still fall, but the fall won’t hurt much if you just hold it in tight until you’re fully rotated. Also, you could try going on a harness if that helps you with the fear. You should also look at your jump technique and see if you are taking off too early. My coach says that sometimes taking off too early & pre-rotating can cause you to pop out near the end of your jump, because technically your body knows you have completed all the rotations, but since you started rotating early, it’s not actually time to land yet. Good luck! Additionally, just work on your in-air position overall. Check out my last answer for some tips on that.
