During ground escapes, what actions are involved to gain space from an attacker?

Gaining space from an attacker during ground escapes is crucial for regaining a more favorable position or escaping a dangerous situation. The action involving knee strikes coupled with pushing away at the attacker's hips is effective as it creates distance, making it harder for the attacker to maintain control. By striking with the knees, you can disrupt the attacker's balance and focus, while pushing away from their hips helps create space needed for an escape. This combination allows you to protect yourself while effectively countering the aggressor's positioning.

Other methods listed, while potentially useful in different contexts, may not specifically target both the immediate need for space and the disruption of the attacker's control as effectively as the selected answer.
