Lol, you barely even started.
Ok, then could you perform this technique.
(Konoha Shōfū) – Leaf Rising Wind
Rank: C
Type: Attack
Range: Short
Chakra cost: N/A
Damage points: 20
Description: This technique uses the entire body as a spring, by amassing power through taking a posture where the back of the body falls down. With this powerful taijutsu, the user kicks just above the head. Because the power of the kick from the ground is instantly converted into a blow, the enemy hit with this attack will be launched high into the sky.
As you can see, this technique (as every other taijutsu technique) requires momentum which you gain by using your whole body as a spring. You throw yourself on the back while simultaneously raising your foot. This allows you to execute a powerful kick which can even launch the opponent into the air. It's obviously best to aim it at your opponents chin but I guess the crotch would work too.
