Good posture is important because it places the least amount of ______ on muscles and joints.

Good posture is important because it minimizes the stress placed on muscles and joints. When the body is aligned properly, the skeletal system supports the body’s weight equally, which reduces strain on muscles. This alignment allows for more efficient movement and function, preventing fatigue and injuries.

Stress in this context refers to the physical tension that can accumulate when the body is not held in an optimal position. Poor posture can lead to increased stress in certain areas, causing discomfort or pain over time. Thus, maintaining good posture is essential for overall physical health, as it protects the musculoskeletal system and promotes a greater range of motion and efficiency in physical activities.
