We always make several turns while approaching the jump before generating a spin.
These turns are made for several reasons, but I’ll talk about it in another tutorial.
This turn is called a Setup Turn.
For example, even if you takeoff on the toe edge when doing a back side spin, the heel turn will turn into a toe turn and you will generate spin.
The stronger you make an edge angle during the setup turn, the more your body’s axis will lean when taking off.
The more your body axis leans, the more your spin axis will lean which will mess up your spin midair.
And by your body falling diagonally, you will jump diagonally towards the landing instead of straight towards it.
These are two problems that can be affected by a setup turn.
Often in tutorials it says that if you take off in the middle of a setup turn that you will jump straight towards the landing, but that alone doesn’t solve the problem.
I had many students that weren’t able to solve the problem like that when I was coaching them.
Even though their lines for their setup turn are straight during takeoff, they would end up jumping off diagonally.
Conversely, I also had students who would jump straight towards the landing even if their boards were rotating and pointing diagonally.
I myself used to always believe in those common tutorials, but I still had students whose problems were not resolved as well as students who would still jump straight without following what the tutorials said, and I began to doubt the tutorials.
I analyzed the videos many, many times and found the origin of the issues that are commonly featured.
I’ve written out the actual findings based on my analysis.
Why does the spin axis end up leaning?
Why do the riders end up going diagonally towards the side of the landing?
These two problems share the same origin,
When talking about back side spins, the riders ride on the toe edge on the last setup turn.
Since it is a turn, it makes the body collapse inside turn arc.
Since the rider takes off and spins with that collapse still there it becomes hard to control it in mid-air and the spin also turns into a cork spin.
The solution is “Straighten up your slanted body”
In other words, put the center of gravity right above the board.
Someone who jumps towards the side of the landing will go to the side regardless of if their board seems to be pointing straight towards the landing or not.
Because of this, you can’t explain the direction of a jump with just the setup turn line.
And, I also discovered that the degree of the direction of the jump is decided by the degree in which the center of gravity leans.
The closer the center of gravity is on the edge, the more strongly the angle leans horizontally.
The more the center of gravity leans, the stronger the angle of the direction of the jump will go horizontally.
Although the edge is angled, there are also people who jump straight.
Our body’s axis will lean inside turn arc if we raise our edge, but something that I’ve also witnessed are people whose upper-half of the body is on top of the board even though their edge is raised.
In other words, their center of gravity is on top of the board rather than inside turn arc, even though their edge is raised.
As a test, try sliding down the Beginner’s Slope and stay balanced while standing on the tips of your toes like Michael Jackson.
Even though your edge is raised you’ll draw a straight line.
Also as a test, see if you can jump and get straight air while standing on your edge.
This time, if the center of gravity stays near the edge of the board, leave the center of gravity on the board, raise the edge and stand up straight on the edge and compare the situations.
This time, compare these 2 for checking your balance while taking off and while in midair.
It’s easy to be able to understand that you will stand up towards the direction your weight is in.
Because your body’s axis leans more or less into the direction that takes weight, and you can only force it along by this axis, you can only stand up towards the direction where your body’s axis is collapsing during takeoff.
Let’s check this one more time.
During the last setup turn, put the center of gravity that’s leaning inside the turn arc back on top of the board.
This is how to finish your set-up turn before takeoff!
Here is a concrete solution!
You can’t focus on all of that at same time.
Let’s find the one that will solve your issue!
