Final answer:
One way to help maintain stability in some backbends is to lower the center of gravity and expand the base of support by placing the feet farther apart.
Step-by-step explanation:
One way to help maintain stability in some backbends is to lower the center of gravity and expand the base of support by placing the feet farther apart. This increases stability by creating a wider support surface and distributing the weight more evenly. An example of this can be seen in Figure 9.26, where good posture places the upper body's center of gravity over the pivots in the hips, eliminating the need for muscle action to balance the body.
