Final answer:
Good posture helps minimize the energy required to maintain the body position by aligning the center of gravity above the hips' pivot point, reducing muscle strain and energy expenditure.
Step-by-step explanation:
Good posture plays a significant role in minimizing the energy required to maintain our body position in space. When we have good posture, our center of gravity is aligned directly above the pivot point in our hips, which eliminates the need for muscle action to balance the body. This reduces the strain on our muscles and decreases the amount of energy needed to maintain proper posture.
