Tutorial of Standing Back Flip

The illustration below is a flow of a Standing Back flip.
In reality, you don’t move that much(An illustration of each form is shifted to right).

Don’t squat too much.
Your knees, hips, and arms should extend up simultaneously; but if you squat too deeply, it becomes difficult.
At the moment you squat most deeply, your arms should be at the bottom.
Like a vertical jump, you should squat and jump and swing your arms.
If you extend your torso too early, your knees will go forward and you won’t be able to extend your knees out.
As a result, the height of your jump and rotation will diminish.
(cf. How to stretch out your knee-joints when taking off)

Swing your arms upward swiftly (Don’t swing by leaning back, but by extending your shoulders).
(cf. Tip2 : Swing your arms upward)

Also, you have to pay attention to not lean back too early.
Start leaning back just before taking off.

At the moment of taking off, lean back slightly, not too much.
(cf. Tip1 : Slightly lean back and jump)

And your arms are above your shoulders.
Your knees must be completely extended out to get as much height as possible.
You should stick your chest out but do not arch your back (But it’s difficult for a beginner).
(cf. Tip 1(common) : Your lower body should be vertical to the ground)

Make sure you are looking forward even after taking off .
(cf. Appropriate direction of your face)

After taking off you should continue to look forward.
You cannot generate more rotation in the air.
The only thing you can do in the air is to increase your rotation speed by making your body smaller (tucking or piking)and putting strength to your whole body.
(cf. Tip3 : Put strength in your whole body while rotating)

You do not initiate momentum or get rotation by bringing your knees up.
(cf. Not Tip1 : When tucking , bring your knees to your chest, not chest to knees)

Rotation has already started from the moment of taking off.
You should get small as soon as possible without thinking after taking off so you don’t lose rotation due to loose muscles.
(cf. Not Tip4 : To generate rotation, tuck faster)

Sometimes the notion that you should tuck as soon as possible prevents you from proper take off.
Therefore, you may want to wait a split second before tucking (or your chest may be hollow as you jump).

After you get enough rotation, you should prepare to land.
Don’t try to force a landing for safety if you are a beginner and cannot rotate enough.
There are two ways to prepare for landing.
Do the opposite of what you did while increasing rotation.
One is to make your body big.
And the other one is to loosen your muscles.
In these two ways, you can slow down your rotation speed.
After that, your can face forward and look at the ground.

Look at the ground and calculate your landing.
Bend your knees slightly in order to prevent injury in case you miss the landing.
After your feet touch the ground, you should bend your knees and absorb an impact of landing.
To stick your landing, you should utilize your arms properly.
