when ever i see people doing corks, they always look down and kinda look like they are tucking and roll. i cant cork myself on snow yet but this is how i can get them into pools and trampoline.
sparknotes: bend down as far as you can and go into a tuck and roll.
Corking on a tramp is easy. if you spin left, like me, you take your right arm and try to grab your left heel. When you jump up and do this it will set you for a cork. how hard you spin will determine your rotation.
spin at decent speed with knees in. your axis and rotation with you knees will do everything for you. you dont need to have a hugggggeeeee cork you can work your way up to a higher tilt in axis. most people just go for it and land in a shitty death spin.
