AFAA Personal Trainer Certification Practice Exam

Core exercises engage which type of muscle groups?

1. Only major muscle groups

2. Single joint isolated muscles

3. Multi-joint large and small muscle groups

4. Stabilization muscles of the lower limbs

The correct answer is: Multi-joint large and small muscle groups

Core exercises are designed to engage a variety of muscle groups, including both large and small muscle groups that work together to stabilize and control movements. This is why the correct answer emphasizes the inclusion of multi-joint and various muscle groups. The core musculature consists not only of the rectus abdominis and obliques, which are larger muscle groups, but also includes smaller stabilizing muscles such as the transverse abdominis and pelvic floor muscles. Additionally, many core exercises engage ancillary muscles in the hips, back, and thighs, which contribute to overall stability and strength during movement. By focusing on both large muscle groups, which can generate significant force, and smaller stabilizing muscles, core exercises enhance functional strength, improve balance, and prevent injury. This comprehensive engagement is critical for promoting overall athletic performance and daily functional activities.
