3. Which is a reasonable attitude toward commenting to students on the policy of locking their knees in standing forward bends?

b) they might hurt themselves by extending their necks that much
c) it places too much tension on the sternocleidomastoid muscles

7. Regarding "bending from the hips" rather than "bending from the waist" in forward bends, which one of the following is wrong?
a) in the absence of good hip flexibility, bending forward at the waist as a priority may place excess stress on the joints and ligaments of the lower back
b) the hip joints are synovial ball-and-socket joints ideally adapted to forward bending
c) bending at the waist as a first priority produces excess nutation at the sacroiliac joints
d) bending from the hips rotates the head of the femur in the acetabulum of the hip bone
e) bending at the waist compresses the fronts of the intervertebral disks between the chest and the sacrum.

8. Regarding twisting postures, which one of the following is incorrect?
a) twists generally produce compression of structures located axially to the twist
b) gravity is often the main issue to be considered in performance of twisting postures
c) spinal twists feature moderate shearing effects of intervertebral disks between adjacent vertebral bodies in the lumbar region
d) standing twists always include synovial rotations at the hip joints
e) sites at which twisting can occur in addition to bending (neck, hip joints, and knees) are frequent problem areas for aches and pains.
