Which of the following is NOT a component of the core muscles?

The quadriceps are not considered a component of the core muscles. The core is primarily composed of muscles located in the abdominal area and those that contribute to spinal stability and posture. This includes the rectus abdominis, which is the prominent muscle group that forms the "six-pack"; the obliques, which are located on the sides of the abdomen and help with rotational movements and lateral flexion; and the latissimus dorsi, which plays a role in controlling the movements of the upper body and the back but is more often associated with the back than the core itself.

In contrast, the quadriceps are a group of muscles located at the front of the thigh, involved in knee extension and hip flexion activities. While strong legs are crucial for overall stability and functional movement, they do not fit within the definition of core muscles that are specifically involved in maintaining torso stability and supporting the spine during movement.
