1. Muscles that comprise the 'core' include ALL except?

2. Prone hip extension performed on a Swiss ball is commonly used for development of which of the following muscles?

3. The Swiss ball was inflated according to the subject's weight in this study, so that when a subject was sitting erect and centered on the ball, with feet together and flat on the ground, the subject's hips and knees were flexed approximately 90 degrees and the thighs were parallel with the floor.

4. Which exercise resulted in the greatest normalized mean (SD) electromyographic signal for the upper rectus abdominis?

5. The crunch and decline push-up elicited the greatest external and internal oblique normalized mean (SD) electromyographic signals.

6. All of the following exercises resulted in very high relative muscle recruitment of the external oblique, EXCEPT?

7. The bent-knee sit-up may be a safer exercise to perform than the crunch for individuals who need to minimize lumbar spinal flexion or compressive forces because of lumbar pathology

8. During the prone Swiss ball exercises, isometric actions from which muscles counteract the forces of gravity to extend the trunk and rotate the pelvis thereby stabilizing and maintaining a neutral position of the pelvis and spine throughout the movement?

9. Individuals with weak rectus abdominis and external and internal oblique musculature or lumbar instability may want to avoid which of the following exercises?
