First of all, we must ensure the standardization of the action. If the action is not standardized, there will generally be problems in the order of force, which will also lead to "borrowing power."

The sequence of troops generally follows three principles:

1, the core muscle group comes first, stabilize the trunk.

2. Big muscles (big muscle groups) exert their strength before small muscles;

3. The muscles close to the trunk exert force before the muscles far from the trunk.
