Pressure map data
"If we strip away the shoes from our basketball elites, Kevin Durant, Lebron James, Russell Westbrook, you'll be shocked to see exactly how their feet work. The shoe is the greatest magician of all time, deceiving our perception"
- Chong Xie
Chong Xie's Principle 1:
There is only one way to engage your glutes properly which is the same mechanism that also lock up your ankle to prevent ankle sprains. This is the intelligent design that most people have overlooked.
Here I show you what it looks like when I am standing in neutral state and when I engage the glutes. This will help people see that when you are NOT using your glutes, the pressure is on the areas that are not made for absorbing force, how can you not get injured?
You can surely try to force your feet to land on the forefoot, but because your ankle is not locked(see demonstration video 1) you will get injured sooner or later.
This is my pressure map when I am standing neutral, feet relaxed state.
(This is why most people including professional NBA players miss free throws, when you stand on the freethrow line, your glutes is NOT engaged!)
This is from using my technique described in the book, with glutes engaged.
This is when I run, sprint and land with glutes engaged mode
Why is the pressure map so important? have you ever wondered why all the running animals of the land have hooves? the horse for example has a gigantic butt but the hooves are so small, this is done by intelligent design, the less the surface area, the more pressure there is and the more force there is.
Picture a thumb tack, if you apply the same amount force backwards from tip of the pin to plastic head, it won't generate nearly as much as pressure as before.
This principle is the same for humans, if we want to perform at high force, high speed level, our feet must morph. Transform into a lesser contact point to the ground. In order to do that we must lift our heels from the ground and use the ball and toes of the feet, the windlass mechanism has to be utilized and gluteus maximus has to be engaged.

This picture shows the hind leg of a bear, dog and deer. The foot of the bear is similar to your foot. The toes and heel touch the ground.
This pattern is modified in a dog. Notice the heel raised up away from the ground.
The deer has only toes that touch the ground.
