Final answer:
To maintain stability in backbends, one should lower the center of gravity and engage the core muscles.
Step-by-step explanation:
One way to help maintain stability in some backbends is to lower the center of gravity. By lowering the center of gravity, the base of support is widened, which increases stability. This can be achieved by bending the knees or spreading the feet apart. Another way to increase stability in backbends is to engage the core muscles. The deep muscles of the core help maintain posture and stability. By strengthening these muscles, one can improve their ability to maintain stability in backbends.
