learn to use your legs more! its always the legs!
dont push with your arms when getting out of a transition leave them at the side or yust retract them
think faster and keep breathing when you stop your muscletention changes,this will bring un controlled movement in the sky (hitting some one).
take a coach let him video debrief practise 5 jumps take the coach again and to start make in this way 50jumps (vacation) and you wil get a stable HD position.
Smile and have fun! most importand one dont get stuck in the yums that didnt go so well look forward and set goals!
