Now put it together. Jump up with your whole body straight like you would for a high backtuck or layout. Do not leave the floor too soon. Push all the way through full extension.
Now here’s a small difference to the set of the backtuck. You will want to raise one arm at a time, instead of simultaneously. The first arm will be the one that directs your twisting direction. So if you twist to your left, raise your left arm first and then the other. This way you’ll get a little bit of twisting momentum.
As soon as you leave the floor - think frontflip all the way. Tuck in tightly just like you would for the frontflip, because it’s just that. A frontflip entered from the back.
