So I learned this move and here are the tips I used (Assuming you can handspring already):
First, lowering to the ground slowly from my handspring. If possible, pause for a few seconds before dropping my feet to the floor
Second, descending to and Iron-X and lifting back to my handspring
Third, standing next to the pole on my tip toes and reaching my top arm up as high as it can, then place the bottom arm accordingly (It should be bent) Try pressing out without jumping so your feet are off the floor, hold, and bring it back down. Once you can do this, try pressing out, and lifting and lowing your hips just a few inches a few times.
MAKE SURE YOUR TOP SHOULDER IS ENGAGED AND PULLING DOWN THE ENTIRE TIME. If it hurts doing any of these, it is not engaged enough. let me know if you want videos!
If you can do all these, you can deadlift :)
