The Pivot
The Pivot is a powerful technique if you know how to use it. The basic idea is to move the center of an object to another location, allowing you to use the Spin Emphasis with a new center.
consider what happens here
notice the movement of the center of the upper leg
that’s the motion path of his upper leg
to illustrate another example, the center of the blue object moves towards the tip of the red object by using a motion path

This is possible by duplicating the shape, positioning them right beside each other, and grouping them to reset the center. This center becomes the most important part of the shape. Then, make the other shape invisible.

The Pivot
Notice that each section of the stickman’s body consists of pivots. Each center plays the role of a joint in his body. One of the centers also acts as the central pivot point where the stickman’s body is touching the ground—in this case, his hind foot.

let’s see it again in slo-mo
Work Efficiency
Use the Curve Tool for your Motion Paths so that you can alter the paths should you need to by using Edit Points. Always start with the central pivot point, and then move towards the pivot points directly connected to the same shape. In this case, if the hind foot is the central pivot point, the next adjoining point is the hind knee.

That’s about it. Hope you learned a thing or two. Keep practicing, and remember:

Stickman Pivot: Working Efficiently
Work Efficiency
So now you know how to pivot. That’s still not going to be enough. You need to know how to make several pivots work together. To do this, you need to use the Motion Path Emphasis in combination with your Spin Emphasis.
The Pivot
The entire animation is divided into four sequences. Each sequence may have a different central pivot point, depending on what point is most responsible for maintaining his balance.
