Crossfit Trainer Practice Test Level 1

Which of the following muscles is NOT considered part of the core?

1. Hip flexors

2. Chest muscles

3. Abs

4. Erectors

The correct answer is: Chest muscles

The chest muscles are considered part of the upper body but are not classified as core muscles. The core is primarily defined as the group of muscles that stabilize the spine and pelvis, enabling efficient movement and proper posture. This group typically includes the rectus abdominis (abs), obliques, transverse abdominis, erector spinae, and hips flexors, which play integral roles in stabilizing the body's core region during various physical activities. Therefore, while the chest muscles are important for upper body strength and function, they do not contribute to core stability in the same way the other muscles listed do.
