Yes
Depends how high you jump.
You run up in a J shape and jump off of one foot. twist in the air to land on your back making sure to flick your legs when your body is over the pole.
land on your feet I mean if you jump from a high distance up and it hurts when you land on your feet how do you avoid it.
when doing a back flip there is not a certain height for it you just literally jump up and tuck back and hope you land it you might have to try a couple of times. but if you can try to practice on a trampoline or on sand dunes if you are near a beach then give it a go.
kangaroos jump high, but frogs jump low. frogs also land on there front legs while kangaroos land on their heels.
by there back legs
No.
There back legs are very strong an when they push down an put pressure on them they jump very high, there leg bones are ment for them to jump cause they dont walk :)
People have sky dived without working parachutes and lived. It depends on how you land and what you land on.
you have to jump high enough to do a 360 in the air
you should have a race bike to jump high. to jump correctly you have to be in the attack position before you jump. the attack position is where you stand up on the bike, knees slightly bent, standing with your butt twards the back of the bike, elbows bent and looking always in front of you. never at the ground. when you are coming twards the jump give it a handful of gas ( still in the attack position until you land) when your in the air grip the bike with your knees to avoid wiping out. when you land make sure your standing and land with a bit of gas to even the bike out.
as long as you can get all 4 wheels off the ground and land on it. it is a ollieit can be as high as you can jump and maybe higher if you are riding
