repetition. your body will start getting more and more use to it and eventually it will stay balanced

I personally found out it's about practice. Your body has to get used to spinning that much. Also, I tried keeping my bounce and my back as straight as possible. If your bounce isn't straight you will go off-axis. Focus on jumping straight up and keeping that stance during the spin. Also, spin hard because if you tend to lack momentum it'll throw you off axis. Finally, I tried adding a grab (mute is the easiest) so it keeps your stance compact and less likely to go off-axis.

Cross your arms and legs and go for it.

Try making sure that your jump is strait up in the air. Alternatively, try just landing the cork and getting legitness points from friends and neighbors

Close your eyes and practice bouncing in the same spot

Just keep trying that's what I did I didn't use any kind of trick to doing it

Get more air

This may be because you are either spinning towards your non dominate side or you might be throwing your arms off axis instead of right or left. #followandlike

Turn your head the way your spinning the whole time

Bring your arms in across your chest like your doing a sit-up. Chin down

Bring your arms to your chest like your doing a sit up

You might be scared. Try practicing with a mat
