Which of the following can increase pressure in vertebral discs?
a. doing leg extensions
b. doing squats and lunges
c. torque while lifting
d. bending the knees while lifting

The correct answer is C. Torque while lifting can increase pressure in vertebral discs.

Explanation:

When lifting in the gym (especially when that weight exerts a downward pressure on the body), athletes should try to keep their body position firm and straight, so that the back remains aligned in a natural position, and not arched or tilted. Keeping that firm posture, the exercise will affect only the muscular part that is performing the movement, and not the back.

If the exercise is performed with the arched back, pressure is exerted on the spine, putting pressure on the vertebral discs, which are already in an unnatural position. This can cause moderate to severe injuries in the athlete, such as herniated discs or low back pain. Therefore, a correct position must be taken before exercising in the gym.
