3. Creating Weight Shifting Animation

Step 1

With the head dummy
selected, go to tenth frame and move the dummy a bit to the left side
to give the weight of the body on the left side when the right leg is up in the
air. You can also rotate the dummy a bit as shown in the following image.

Shift the weight to left leg

Step 2

Go to twentieth frame and keep the placement and rotation of the head dummy back to its initial
position as shown in the following image.

Back to initial form
Back to initial form

Step 3

Once again with the head
dummy selected, go to thirtieth frame and move the dummy a bit to the right
side to give the weight of the body on the right side when the left leg is up
in the air. You can also rotate the dummy a bit as shown in the following
image.

Weight shift to right leg
Weight shift to right leg

Step 4

Go to fortieth frame and keep the placement and
rotation of the head dummy back to its initial position as shown in the
following image.

Back to initial form
